Love for the Moore 24

• By Ronnie Simpson
• Updated: March 27, 2013

Designed in the 1960s and first produced in 1972, the Moore 24 led the way for an entire generation of ultralight-displacement boats that would serve to cement the place of Santa Cruz, California, in the annals of yacht-racing history. Designed by famed surfer and sailor George Olson, the Moore 24 was first conceived as the longest, lightest way to make a racing keelboat that would use a Cal 20 rig. In the strong summer breezes and big swells of Monterey Bay and the San Francisco region, the little speedsters immediately proved their merit with solid construction and unrivaled off-the-wind performance, surfing past 50-foot IOR designs in local offshore races.

In 1975, a Moore 24 was sailed doublehanded to Hawai’i, further proving the boat’s seaworthiness. By 1980 production and popularity was at its peak, and three of the boats raced one-design in the biennial Singlehanded Transpac, a solo race from San Francisco to Kaua’i. The boat’s lightweight, easily handled sail plan and well-mannered, bow-high surfing characteristics made it a favorite of local ocean racers, earning an impressive racing record in the challenging Gulf of the Farallones and the Pacific Ocean.

Over the past 40 years, the Moore 24 has become an ageless classic in Northern California and all over the U.S. West Coast. With one-design fleets in Santa Cruz, San Francisco, and the Pacific Northwest, you’ll often find more than 30 boats at a big regatta. The 24’s cult-like following and long list of talented owners is a testament to the longevity and durability of this superb design.

In addition to one-design contests, Moores regularly win mixed-fleet races to this day. Collecting hardware in weekly beer-can races, local offshore races, and even races to Hawai’i, the oversized presence of the Moore 24 on the U.S. West Coast belies the fact that only 156 boats were built. Continuing their rich ocean-racing tradition, two Moore 24s were sailed singlehanded to Hawai’i in the 2012 Singlehanded Transpac. In a class that included several other Santa Cruz ULDBs and even a Transat 6.50, the Moore again reigned supreme, earning yet another class win in Hawai’i.

Moore 24 is a 23 ′ 9 ″ / 7.2 m monohull sailboat designed by George Olson and built by Moore Sailboats between 1972 and 1988.

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)

Solo Pacific sailing: The adventures of Webb Chiles and his Moore 24 Gannet

• June 1, 2020

Single-handed adventurer Webb Chiles outruns a south pacific storm as he sails between the US and New Zealand

Webb Chiles’s Gannet is a George Olson-designed Moore 24, a long-distance race-winning ultralight yacht built in the US

During the night the barometer dropped steeply and the wind began to veer. Now finally it was on the beam, which was good and bad. Gannet wasn’t thrashing into the waves, but she was heeled 30° to 40° and when waves broke, they rolled her dangerously.

Taking a flotation cushion, I made my way aft to the tiller, untied it and turned Gannet a bit farther off the wind, braced myself with my left sea boot on the far side of the cockpit and my right on the post through which the backstay controls run up to the mainsheet traveller bridge.

The overcast was dark, solid and low. It seemed to press down on Gannet and me. I could feel its weight. Rain was falling, colder than the water from the ocean.

Although it was 0900, the light was that of pre-dawn; and when darker lines came toward us, which I quickly learned meant a 5 to 10 knot increase in wind and torrential rain, the sky was night, but the surface of the ocean frothed ghostly white by wind and splashing rain drops.

Gannet was not hard to steer. But I lost vision in my right eye a few years ago and the waves were coming from starboard, slamming unexpectedly into and over us, literally blind-siding me – hard blows, as though being punched by a ranked heavyweight. Several knocked me from my seat, lifting my body so that I started to fall forward and down into the sea.

I couldn’t possibly leave the helm long enough to go below to get my safety harness so, steering with one knee, I looped a sail tie through the slotted toe rail and tied a bowline as a strap for my right wrist. As long as my arm remained attached to my body, I was going to be attached to Gannet .

When the heaviest rain hissed down, I couldn’t see the mast-mounted Velocitek and steered by feel, turning Gannet and surfing down waves. She ran beautifully true with no tendency to round up, her bow waves rising above the deck. When visibility returned I often saw speeds of 11 and 12 knots on the Velocitek, but by then Gannet had slowed, so I don’t know how fast she may have gone. Whatever the number, it’s the fastest I’ve ever sailed on a monohull.

I couldn’t see my watch, but after what surely had been an hour, I started looking for land. Cape Wiwiki should be off the starboard bow. Cape Brett off to the south. But I found only cloud.

I had to twist my neck a long way to see the oncoming waves. Surfing down some, I turned up into others. A split-second decision, often based on how much crest was toppling, sometimes just on instinct. Still a few caught us and rolled Gannet almost to 90°, until feet braced, tiller in left hand, sail tie strap around right wrist, I was standing straight up almost parallel to the sea. As the wave passed gravity bought Gannet back onto her keel and sat me down.

Beneath my heavy set of foul weather gear, I was wearing a Polartec fleece and Columbia Omni-heat pants over my usual shirt and Levis. Despite rain and wave, they were staying dry and only my exposed hands were cold. My left knee began to feel the constant strain. I tried to ease it and take more weight on my right foot.

Breakfast is usually oatmeal, trail mix, dried fruit, protein powder, dried milk and water

The last position I had seen on the iNavX app on my iPhone I use as Gannet ’s primary chartplotter before coming on deck put us 24 miles north of the waypoint at the entrance to the Bay of Islands. Surely we had covered seven or eight miles since then. But still no land.

Another estimated hour passed. We shouldn’t be more than 10 or 12 miles out. Perhaps less. Something should be visible. And then off to the south, clouds thinned and Cape Brett materialised followed by the ridge of land leading west from it.

Pleasure flooded over me, as well as water, both at seeing the familiar landmark – I based my last boat, The Hawke of Tuonela, in Opua for many years and the Bay of Islands is my favourite place in the world to keep a boat – and because it was the first solid indication that we were likely going to make it in before the wind backed.

At 78 years of age, Chiles still loves ocean passagemaking

A little later Cape Wiwiki appeared much closer. I began to steer more toward it, wanting to stay to windward as much as possible. I knew that even this close, we could still be in trouble if the wind suddenly backed and we were forced outside Cape Brett.

The low overcast continued to lift and patches of blue sky appeared ahead. I expected the wind and seas to diminish as we closed the distance to the land, but they remained at strength until Cape Wiwiki was abeam. As we entered the partial shelter of the nine-mile wide mouth of the bay, I was able to tie down the tiller for a few minutes and duck below to grab a protein bar and use the piss pot.

Gannet ’s bilge has a narrow sump. Usually in rough weather a couple of inches of water a day collects there and I pump it out with a hand pump that has a hose long enough to go out the companionway and reach overboard. Now heeled only 10° to 15°, the bilge was overflowing. I got the pump and emptied it. But when I went down later it was full again and I began to wonder if I had a problem.

Forepeak is used for sleeping in harbour

I took the protein bar back on deck just in time to see two of Gannet ’s handsome namesake birds glide across our bow. We still had 14 miles to reach the Quarantine Dock at Opua. While the water was smoother, lee rail-burying squalls continued to hit as we sailed deeper into the bay. I furled and unfurled the jib like a venetian blind, and alternately hand-steered, tied down the tiller, hand-steered…

Familiar islands drew closer. A cloud of birds around Bird Rock, white with guano. Vivid green hills. Exposed brown cliffs falling into the sea. Tiny foot long penguins bobbing on wavelets. I smiled when I saw Paradise Cove on Urupukapuka Island where I’ve often anchored and the lookout platform high on Roberton Island to which I’ve often hiked.

Not until we made the final dogleg turn beyond the rocky ledge off Tapeka Point just north of Russell did the wind moderate. I brought Gannet about and hove to so I could fit the outboard bracket, Torqeedo, fenders, dock lines and ‘Q’ flag. Then I turned us again and continued south under sail. I knew the way.

Sailing in Neiafu, Tonga, before the start of the passage to New Zealand

Just north of the car ferry crossing, within sight of the Quarantine Dock, the wind died. I furled the jib, turned on the Torqeedo and lowered the main. Misty rain began to fall as we covered the last 200 yards at dusk. Opua’s Quarantine Dock is the easiest to approach of any I know in the world. I had Gannet prepared to tie up port or starboard. With no wind, the tidal current was decisive. It was running out, so I continued forward to tie to port.

We were weeks ahead of the herd of boats sailing across the Pacific . The long marina breakwater, of which the northern 200 yards are the ’Q’ Dock, was empty. I turned the Torqeedo tiller arm to neutral, glided the last few feet, stepped off and tied dock lines. Then back on board to duck into the cabin for the bottle of Laphroaig in which I had saved an inch for this moment.

My two crystal glasses did not survive the Pacific, so I poured into a plastic tumbler, straightened up and, still wearing foul weather gear, stood in the companionway indifferent to light rain, which was nothing compared to the total immersions of the morning. The little sloop’s deck came to just above my waist. I looked around at familiar hills and took a sip. Then another.

Sailing in the Bay of Islands a week after arrival in New Zealand and trying out a new North G2 asymmetric gennaker

The date was September 20, 2014. We had sailed from San Diego on May 20, 6,400 miles in four months. Actually because of crossing the International Dateline, a day less than four months.

Passage over. Ocean crossed. And, though an American not a New Zealander, I was home. The wind backed to the south-west that night and increased to 50 knots, closing the door on a 31ft cutter that left Neiafu the day after Gannet . She reached Opua a week and a day later. Water continued to trickle into the bilge from odd corners of Gannet ’s interior for several days afterwards and then stopped.
