Harmony 38 is a 38 ′ 3 ″ / 11.7 m monohull sailboat designed by Mortain & Mavrikios and Olivier Poncin and built by Harmony Yachts starting in 2004.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Draft for twin Keel vers.: 1.55m/5.09’

The Harmony 38 is a 38.29ft fractional sloop designed by Mortain & Mavrikios and built in fiberglass by Harmony Yachts (FRA) since 2004.

The Harmony 38 is a moderate weight sailboat which is a good performer. It is reasonably stable / stiff and has a good righting capability if capsized. It is best suited as a coastal cruiser. The fuel capacity is average. There is a good water supply range.

Review of Harmony 38

Basic specs..

The boat can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Harmony 38 is 1.97, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Harmony 38 holds one CE certification:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.7 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Harmony 38 is about 257 kg/cm, alternatively 1440 lbs/inch. Meaning: if you load 257 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1440 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is Displacement Length Ratio?

SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 18.46

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 43m 2 (462 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.

Has anyone got one and any input welcomed.

Ooops... my post may be irrelevant. The one I know is a CC and looks totally different than the straight 38.... One of the nearby boats is a Harmony 38 center cockpit. Looks like a proper sea caravan with a large aft cabin and large fore cabin. High freeboard would give nice windage too.... Seem well built. Shallow keel and short mast indicate a sedate cruiser. Only goes out when weather is totally benign; = twice a year. Austrian built and they have no access to the sea... says a lot doesn't it? GL

I dont think you guys are talking about the same harmony.... I think Csail is asking about the Group Poncin yachts built in La Rochelle..... Company was started by the guy who restarted Dufour in the late 90's.... I think they went bust last year...(??) I looked at a earlyish 34 and it left me a bit cold...I thought the interiro was not very nice, with countertops without fiddles... and a stark appearance overall... under winched... nasty looking hull/deck join..... the inboard genoa sheets looked both too short and too inboard to work effectivley..... There were some nice ideas like the toerails, bowsprit... but overall dissapointing. I think in the end they tried to spruce up the interior... but they didnt seem to sell well and as a result I think they will be difficult to shift, as they are not really modern in their style... and I dont think as functional as the big boys (JenBenBav.) Frankly, I wouldnt. But if its cheap enough and you like it....  

I did a test sail on a Harmony 38 when they first came out. The one I tried was built by Poncin and distributor was based at Hamble Point Marina. IIRC it had 2 cabins and a aft storage locker/ could be quarter berth or workshop. At that time circa 2002? It was a fast cruiser and had done very well in the RTIR. Suggest you look up results. Fairly sure it was an aft cockpit. As I had a Dufour 38 at the time that had been project managed by Poncin and was far better sailing boat that our previous Dufour 36 I was interested but the layout of the boat we test sailed was not suitable for charter market. I was impressed with the way it sailed. I think the confusion is coming in because Portway yacht distributors sold Dufour yachts and a range of CC yachts built in Austria that were called Harmony. I do not believe this range had anything to do with Poncin. I looked at various models at boat shows as I had bought 2 new Dufours from Portway. These Harmony yachts were a good value CC cruising boat. Hope this helps

Nick Vass said: Thanks CFarr Probably best to keep your negative comments to yourself Pete, unless you have actually seen one of these boats. I don't wash up whilst sailing. I don't care if you think that it might be a 'marina caravan'. You don't own it. Plus you have not seen one. We like ours, it sails well and looks good. We have plenty of space and a sensible interior, which is why my daughter was sailing on it aged 3 months and still loves it now. My son has his own cabin and all family happy to go sailing almost every weekend April to October. Spoent all of summer school hols sailing. Can many families say that? Caravan? Don't care what you think! Many cross channel trips BTW. Lots of sailing even in rough weather. You don't mention what yacht you own? I would not think of rubbishing someone elses boat Pete Click to expand...
