THE AMYA

AMYA Boat Classes

The Ten Rater is a medium-sized yacht with a reputation for speed. This development class is restricted by a simple formula of waterline length multiplied by sail area, multiplied by eight, to equal ten or less. As there are few restrictions, the class allows the greatest freedom for development and experimentation. 60-65" long.

The 36/600 has an appearance similar to the Marblehead yachts. This development class is restricted in overall length and sail area. While these yachts are commercially available, their simplicity also makes them a good choice for beginning builders. 36" long, 600 sq. inches sail area.

Also called "M" or "50/800". The Marblehead is a medium-sized yacht providing exciting performance and the ability to handle most sailing conditions if rigged properly. This development class is restricted in overall length and sail area. The Marblehead was considered the leader in the use of advanced construction materials and techniques. 50" long, 800 sq. inches sail area.

The Canterbury J originated in Christchurch, New Zealand, based on the J Class Ranger. A 48 inch Fiberglass hull and lead Keel both made from Class molds. Everything else can be made by the builder. Total weight of ready to sail boat is 14lbs 5oz.

The Columbia 42 is a semi-scale 12 meter model of the Sparkman and Steven's designed winner of the America's Cup. This boat was generally accepted as the best sailing of the 12's and also the best looking boat on the water.

The CR 914 is based on the original design of the International America's Cup Class.This one design class allows no variations in hulls, spars, sails or replacement parts. 36" (914mm) long, 658 sq. in. sail area, 6.25 lb displacement.

The DragonFlite 95 is a Restricted One Design boat that is meant to compete within a strict set of rules to ensure a true test of a skipper.s ability to tune their boat and race it well.

The DragonForce 65 is the fastest growing class of RC sailboats in the U.S. The boat has earned this distinction by being a great one-design sailing boat while being the least expensive ready-to-sail boat on the market. At around $300 for a boat with radio and receiver and about 2 hours of assembly and you're on the water.

Based on a 1962-63 vintage design for a full-size International 12 Meter. This medium-sized yacht's hull must be initially purchased from a licensed builder. Decks and sails are strictly controlled, purchased or made from scratch. Almost all other equipment is up to the owner. Approx 58" long.

One Design Class sanctioned in 2002. The Fairwind is built by One Manufacturer. The Kyosho Fairwind are 36" (900mm) long replicas of International Offshore Racing (IOR) yachts with cabins.

Sanctioned in 2006. Low cost, fun, easy to build class that puts to rest the theory that boats under 30" long don't sail well. 12" long (thus "Footy") is the smallest of the development class yachts.

The Infinity 54 is an original design expressly for model yacht racing. This one design class allows no variations in either original assembly or replacement parts. 54" long.

Sanctioned in 1998. The International One Metre is the fastest growing class in the world. The rules in this class are identical to those used throughout the globe. The class has a one-design rig and weight minimums, but the hull design is very much developmental. One meter long, with a sail area as large as a Marblehead. 39.37" long (One meter)

The J class yachts are 1/16 scale versions of the original 1930's J-boats only, making it the largest of all the RC yachts. These classic yachts recreate the style of yachting's Golden Era, on a grand but affordable scale. Approx. 85-95" long. The largest class in the AMYA, the "J" boat

Canterbury J

The Canterbury J Class model originates from the Christchurch Model Yacht Club in New Zealand in response to the problems the club members were experiencing sailing models with finned keels in weedy conditions, a problem that all model yacht skippers will be very familiar with and the Canterbury design is a practical solution that remains very relevant to current social and racing skippers today. The objective of this original design is for a model with good sailing manners, that can be easily transported, can be made at comparative low cost and that can be raced in a variety of conditions including weed.

The Nottingham version is the same model when built and is recognised as such in the UK but as the hull is not taken from an approved Canterbury mould cannot be raced against other Canterbury's outside the UK. If you intend to race outside the UK then you will need to buy a Canterbury.

rc j class yacht

The principal difference between the Canterbury and the Nottingham is that the ballast for the Canterbury is external, being bolted up to the bottom of the hull to complete the keel whereas the Nottingham version has the same ballast placed inside the hull, which is now a full moulding. The rudder is also slightly different as the lower rudder pintle is different on the Nottingham version and the Nottingham rudder has a small cut out to accommodate the shape of the pintle.

rc j class yacht

I n other respects the model is the same. The same internal woodwork and deck can be used, also the rigs are the same. Those clubs in the UK that race J will generally adopt the Canterbury Association Rules and a link to these rules is provided on this site.

The build process is slightly different in so far as fitting the ballast externally will require that filler is used to smooth the joint between the ballast and the hull and the hull will then require painting to finish.

rc j class yacht

This picture shows the ballast, the same for both the Canterbury and the Nottingham 48. The model builder will drill two holes in the bottom of the Canterbury moulding and bolt the ballast up to the hull. The trim weight fits inside the hull and the aluminium strip can be used to support a lifting handle on the deck.

I suggest that a layer of filler is applied to the bottom of the hull and which will be squeezed out as the bolts are tightened, this should avoid any air pockets.

J class boats

In 2020 we saw an interesting development with one semi scale 48inch Nottingham J class appear and sail regularly. Since then there have been some interesting discussions around the J class RC boats. In late 2020 an enterprising group of 5 club members decided to build 5 Lionheart J class 60 inch models and while it is a long term project for all of the builders at least 3 boats are within a few months of being on the water. As well we have just learnt that there are 5 new 48 inch Nottingham J class boats in build or on order. To date we know of 6 Nottingham 48s, 5 Lionheart 60 inch, plus a couple of historic boats including K class.

A Brief History of the Canterbury J Class Model Yacht

Sailing at the Christchurch Model Yacht Club [CMYC] in 1996-1997 there was a small classic J Class model yacht named RANGER with a length of 1.2 metres and this was owned by Dave Heanly. This yacht was J1 which was eventually purchased from Dave and is now on display in the CMYC club rooms at Hagley Park.

Ranger J1

A group of CMYC members decided the J Class yacht would be ideal for easy fully rigged transport and sailing in weedy conditions at Lake Victoria.

The hull of number J1 was purchased from Model Boats and the sail plan designed by Hugh Hobden. An approach was made to purchase more hulls. Euan Sargison negotiated and another 9 hulls were purchased and sold very quickly.

The J Class Squadron was formed 2 Sep 1997. Two more hulls appeared making the total at this time twelve.

More hulls were in demand and the place that originally sold the hulls advised that the mould had been lost. After investigating it was found that the original hulls supplied had been taken from a Timaru J Class yacht.

It was decided to make a Canterbury mould with adjustments. The hull was deepened by 16mm and the lead reduced by 16mm and the trim weight put inside the hull. The J Class squadron purchased the new mould with a loan from Peter Vincent and the loan was repaid from hull sales. Number J13 was the first hull

To promote the sailing class three trophies were donated by Peter Vincent.

The basic philosophy was to have an easily sailed and economically built  RC yacht’ based on a one design principles to provide good resale value, and with racing dependent more on the skipper rather than designer/builder skill.These objects have been attained and the Class has attracted many first time sailors, mostly from the retired ranks who share the common creed, “it sure beats gardening!”

The boat can be transported easily in the average car or station wagon fully rigged. Many boats have features of the original Canterbury J Class.

The “Wednesday Windlers” can muster fleets of 30 plus for their around-the-lake sailing on Lake Victoria. Why not visit the lake on a Wednesday? Members turn out, except in the most atrocious weather, and are pleased to “turn over the controls” to any interested spectator.

J-fleet_historic4.resized

377 hulls [December 2022] have been purchased and they are to be found in all areas of New Zealand and as far afield as the USA, Australia, Canada, Germany and the UK. It is a one-design yacht and all hull shells, keels and trim weights are made from moulds officially approved by the Canterbury J Association with an identification number moulded into the hull.

There are rules that, prohibit exotic materials, define a fixed minimum weight, strictly control dimensions in the three sizes of sail rigs.

The yacht can be bought as a kit or in separate pieces and assembled as the budget allows. This also allows members handy at making small components to make many of the parts and keep the price down. All parts are available: hulls white polyester, keels, brass fittings, and computer-generated sails, winches and radio gear. If you cannot find the part you want we will find it or we can make it at reasonable costs.

There is also an active and increasing North Island fleet sailing out of the T auranga Radio Sailing Club  Gilmour Lake  Waihi , [links to external sites] , Palmerston North and Auckland

J Class Yacht Rigging Question

I am launched into a new project building a J Class yacht for a friend (Amati Shamrock V) and I have a question about the rigging that maybe someone knows the answer to.

The kit provides only natural coloured line (ecru, tan, off-white or whatever you want to call it) and the picture of the model on the box shows all of the rigging (both running and standing) done in this colour. Somehow this doesn't seem right to me. Since this is a 1930's era yacht, would it be correct to believe that the standing rigging would actually have been wire cable. Somehow that seems likely to me. Does anyone out there know?

On my Bluenose model the plans stated that all the standing rigging on that vessel was wire cable and had serving. (I didn't have a serving machine at that time, so just ignored this and simply used black line.) If the rigging on Shamrock V is wire cable, is it likely to have been served as well? Somehow that seems less likely to me. Again, if anyone knows, I'd be grateful.

If the standing rigging is wire cable and is not served, what do people think would be the best colour line to use for it. Simply black, or stick with the ecru line provided or would you do something unusual, such as gray. (I'm not going to try my hand at using actual wire.)

Anyway, any thoughts you have would be much appreciated.

America’s Cup competition has always featured boats built with high tech features to gain a competitive edge.  This was as true in the 1930’s as it is today.  Furthermore, the very tall Marconi rigs were highly stressed and rigging was tuned (highly tensioned) to provide optimum performance.  Stretch had to be minimized.  As a minimum the J boats would have been rigged with wire rope.  In later years America’s Cup yachts featured solid rod rigging. More research needs to be done to determined which was used.

  • mtaylor , allanyed and Bob Cleek

According to Llewellyn Howland III in his biography of W. Starling Burgess, the first large yacht to utilize solid bar rigging was the 1934 America’s Cup defender Rainbow.  The bars couldn’t be produced in long enough lengths requiring turnbuckles half way up. Shamrock V would, therefore, have been rigged with wire rope.

 Apparently, the J Boats also used wire rope for some running rigging.  Burgess, became marooned atop Enterprise’s mast when he used the main halyard to hoist him up. The wire rope halyard was heavier than he was!

I know it is a 7 hour drive from Cobourg to midtown Manhattan, but if you can do it, contact the  office of the chairman of the Model Committee at the New York Yacht Club to arrange a visit.   I think the current chairman is Peter Sweetser.   In years past they left me alone for a few hours with the collection to make sketches (but no photos at the time.)   Perhaps now they will also allow photos.    It is a fascinating collection of over 1200 of some of the best schooner and racing models in the world.

PLEASE take 30 SECONDS and sign up for the epic Nelson/Trafalgar project if you would like to see it made into a TV series.   Click on  http://trafalgar.tv     There is no cost other than the 30 seconds of your time.  THANK YOU

Thanks for the input, guys (and the stories too.) That's pretty much what I guessed to be the case. I don't think I'll try using wire for the standing rigging however; I'd never get it lay straight and even and I imagine just a slight touch might put a slight bend in it. I'll probably just end up using black line, but maybe I'll experiment a bit with a metal-like colour.

Allan, thanks for the information about the NYYC model collection. I had a look at their website and I think That would certainly be a great place to visit, however, I don't see a New York adventure in my near future (let's be honest, I rarely leave the basement!)

Thanks again,

Every year during the SNAME conference there is a dinner for Naval Architecture  alumni of the University of Michigan. While not a SNAME member, I always get invited.  One year the dinner was held at the New York Yacht Club.  Unlike most yacht clubs it’s in the middle of Manhattan, not on the water.  I was able to schedule other business to be in NYC to attend the dinner.  As Allan writes, a visit to the club’s model is an opportunity not to be missed.  The model collection is spectacular and I don’t think that they are about to put them in storage to make room for a more “relevant” display.

I would suspect that Shamrock’s wire rigging would not have been served.  Designers of these yachts were concerned with the aerodynamics of the rig.  They would have tried to minimize the cross sectional area of the standing rigging to cut wind resistance.  

Here again, more research is necessary but I believe that the racing rigs were considering to be “temporary.”  When these challengers crossed the Atlantic to race, if sailed they did so under reduced rig. Later the Cup Rules allowed boats to be towed or shipped on a steamer.  The racing rig was erected upon arrival in the US for competition.  Some of the American J’s were furnished with several masts that could be swapped out during the trials.  In any case,  these boats did not have long lives.

2 hours ago, David Lester said: but maybe I'll experiment a bit with a metal-like colour.

I look forward to following your build log David.   I totally agree that using wire is a nightmare.  I had more pin holes in my fingers in one session than all the tiny cuts from scalpels over 40+ years.   I have a couple spools of the stuff in the shop that will take care of hanging pictures for the rest of my life.  Do try getting some metal like thread instead of the wire.   Would the wire color be more towards black than grey?  It easy to make crimps regardless of the color to avoid serving but  I am not so sure seizings and serving was not used on racing yachts 100 years ago,  Roger you probably have it right, but was this the norm when Shamrock V was in her racing heyday?   I suspect some research should turn up some contemporary photos that will give the answer. 

Shamrock V displaces 146 tons. There is a rule of thumb that for a racing yacht the breaking strength of the shrouds should be equal to the displacement. A quick check of a wire rope table says 2” wire rope is 320,000 lbs, close enough. At your scale that would be 0.025”. I don’t know if they were using rod rigging yet, but that would obviously be a little smaller. I doubt they had gone to oval cross section yet to reduce windage.

The pictures of Shamrock in the present day are all clearly rod rigging.

Per my post above, The first J Boat rigged with rod rigging was the 1934 American Cup defender Rainbow.

There is an interesting connection between prewar yacht design and the aircraft industry.  Starling Burgess, Rainbow’s designer designed airplanes in the 1920’s, and Sopwith, builder of the famous  Sopwith Camel owned one or more of the British challengers.  Designers of these high performance yachts, therefore, would have followed developments in building high performance aircraft.  Burgess was also involved in the application of aluminum for boats and cars.  Burgess used proprietary fittings for attaching rigging to Rainbow’s spars and the hull.

High quality small diameter diameter wire rope can be bought from fishing tackle suppliers.  It is used for towing “downriggers,” heavy lead weights used to control depth of fishing lines.  I also have a stash of very small diameter stranded wire cable that I used many years ago in an unsuccessful attempt at control line model airplane flying.

Dr PR

You can find small multi-strand wire in jewelry supplies in hobby stores.

I have some Beadalon brand 7 strand at 0.012", (0.30 mm) 0.015"  (0.38 mm) and 0.018" (0.46 mm) diameter. I also have some nylon coated Cable Strand Corp. Acculon brand 3 strand at 0.012" (0.30 mm) diameter.

I have no love for working with any kind of wire, but that has been my experience so maybe time for another try using the wire you mention.   Are you using crimps or some other securing method and do you find it difficult to keep things tight?   Pictures???? Thank you very much.

The J Class has its roots in the oldest international yacht race in the world, the America’s Cup.

rc j class yacht

Our Heritage

Considered some of the most beautiful yachts ever built, the story of the J Class is defined by fierce transatlantic competition for the America’s Cup, followed by an era of steep decline, and the modern-day revival.

rc j class yacht

The J Class includes a mixture of refitted surviving yachts along with a number of new yachts faithfully built to original hull lines from 1930’s designs, with more yachts currently in build.

(original concept 2005-2007)

Under the piazza levels the 2-storey retail mall connects the Evolution Tower with metro station and pedestrian bridge over Moscow river, thus integrating the new development into the large Moscow-City district, the Europe's newest and most ambitious high-rise cluster (7 of 10 highest European skyscrapers ae located here), housing over 4 million square meters of office and retail areas with associated transport and engineering infrastructure.   

The Evolution Gallery mall houses food court and 6,000m2 family entertainment and educational center for various children activities (the first center of that kind in Moscow). 

The 82,000m2 office tower has 52 levels rotated 3 degrees each floor with overall twist reaching 156 degrees clockwise. With world’s largest innovative cold-bent glazing the tower façade provides seamless floating reflection that rotates the panoramas of Moscow skyline vertically, where the reflected clouds moving up enhance the dynamic visual impact of the twisted tower, an unprecedented optical effect in the world architecture.  The Crown with supporting steel structure made of two twisted arches provides the helipad at the very top as well as the open observation roof decks at Levels 51-52 featuring the best panoramas of Moscow riverside with views towards the historical center. 

From the very beginning the developer and architects have set an ambitious task to create a recognizable and symbolic tower, the new icon of contemporary Moscow.  The sculptural DNA-shaped twisting tower symbolizes the evolution spiral with the white façade ribbon wrapping over the roof in a form of 90-degree twisted infinity symbol, which speaks of philosophical concept of evolution and celebrates the development of human civilization. From spiraling onion domes of St. Basil to the iconic Tatlin Tower concept the Russian architecture was obsessed with idea of spiral. The simple and innovative design was based on principles of twisting square-shaped floor plates with vertical structural RC frame supported by a central core and 8 columns with continuous beams and 4 spiraling columns at the corners. 

The proposed structural scheme with cantilevered continuous RC beams and cantilevered floor slabs  picking up the overhangs from the twisted floor plates appeared to be simple, efficient and economical. The complex sculptural tower façade envelope was built using the innovative cold-bent glazing with flat double glazed units cold-formed in 3D within the aluminum frame under its own weight to avoid stepping in geometry. This approach appeared to be both more energy-efficient and more cost-efficient solution in comparison to the stepped curtain wall units previously applied in some twisted unitized facades. 

The multifunctional architectural glass by Guardian significantly reduces the solar gain whilst providing the double glazed unit thermal performance equal to standard triple glazed unit normally used in Moscow to withstand harsh winter conditions. The use of innovative TWIN elevators by ThyssenKrupp saved 2 shafts within the core (10 TWINs instead of 12 double-deckers in the original concept) and contributed to the overall project sustainability with lesser power consumption per passenger. Other sustainable design features include green roofs over the retail mall and integrated coil floor heating under landscaped civic piazza levels using the return water in winter to melt the snow and ice for the safety of pedestrians. The reinforced concrete formwork by PERI, including self-climbing ACS formwork specially designed for the twisting corner columns, allowed to achieve the impressive speed of RC frame construction of 6 days per floor due to perfect site logistics by Renaissance Construction as main contractor. 

All innovative design solutions and optimizations secured the delivery of this fairly unique skyscraper within the project plan and almost within the budget of the standard ‘benchmark’ high-rise building. This turned out to be a major achievement of the design and construction teams. 

The organic twisting silhouette dominates on its background of extruded glass towers greatly contributing into the overall composition of the high-rise Moscow-City cluster. The development delivered a significant open public space on the landscaped roof of the retail mall, thus providing the perfect mix of business uses with public and social activities of the civic plaza and the mall with its food court and core family entertainment function. The synergy of that mix with large underground car-park complemented by the direct link to the metro station and pedestrian bridge as means of main public transportation secured the successful project completion with the recent entire tower acquisition. Bold shape and timeless aesthetics as added values brought by its unique architecture materialized in a commercial success of this project with the tower being fully acquired for corporate headquarters even in the context of oversupply in the Moscow office market. The outstanding quality of architecture and its fine detailing, state of the art building services and communications of Class A office Tower together with the highest level of transport accessibility  (direct access to metro station from the lobby, large car-parking, proximity to boat pier and helipads) make this property very attractive for tenants and visitors. The beautiful riverside panoramas from offices are complemented by green roof and water features of the large 2ha terraced civic piazza as the main recreational outdoor space with direct link from the office tower lobby. 

The highest quality of façade cladding, glazing, vertical transportation and MEP equipment from leading European and international suppliers provided the truly Class-A office environment with the luxury of minimalist spirit in the architecture of the new landmark on the Moscow skyline. Even before its completion the sculptural spiral of Evolution Tower, more often appearing in commercials, posters and magazines, became a new icon for modern Moscow as the symbol of its business ambitions and fast development. The Evolution Tower also became the monument to the courage of its developer (Snegiri Group) and investors, who built the great deal of trust with architects, engineers and contractors by investing their efforts and funds in a challenging adventure of designing and building the unique and innovative skyscraper for the capital of Russia.
