Seller's Description

The First 310 rides on the award winning Figaro 3 racing hull designed by Groupe Finot for Beneteau. In order to increase headroom the freeboard was increased by 6”. The cabin packs a lot into the space with standing headroom throughout and berths for six. Forward is a private V berth, then a saloon that seats six, then a galley to port and a nav station to starboard with the ice box convenient to the companionway. Aft to port is a generous stateroom and to starboard is the head with a shower. Stowage is generous and near at hand in all cabins and especially so in the galley.

Beneteau commissioned Phillipe Starke for the interior design which is executed in cherry and featuring a circular motif in all the details including two portholes set low in the cabin, just above the waterline offering a constant reminder of the vessel’s progress while underway. The interior is light and airy thanks to the forward hatch and numerous lewmar ports.

“Ondine” is a shoal draft 31’ vessel drawing only 4’3”. In keeping with the revolutionary designs of the 1990’s the stern sections run broad and make for a large aft stateroom to port and a large lazarette under the starboard bench in the cockpit. This vessel is fast around the cans, with a displacement of only 7500 lbs. and a combined sail area of 460 sq. ft., the SA/D ratio is over 20, “Ondine” ghosts along in light air and really comes into its own once the breeze picks up to 10 knots. The sweet spot is in the teens, where the boat shines and easily gets into a groove with a light and well balanced helm. At 18 knots it’s time for the first reef. The main has two reefs and the roller furling genoa allows for fine tuning of the sailplan. The jib sheets are set close, providing excellent pointing.

The cockpit is highly ergonomic and comfortable while heeled. All lines are led aft making it unnecessary to go forward unless setting the asymmetrical spinnaker. There is a custom stowable table at the binacle and stern seats have been added for passenger seating away from all the action at the winches and wheel.

Equipment: Part of their racing lineup, the First 310 rides on the award winning Figaro 3 racing hull designed by Groupe Finot for Beneteau. In order to create more headroom, the freeboard was increased by 6”. The cabin packs a lot into the space with standing headroom throughout and berths for six. Forward is a private V berth, then a saloon that seats six, then a galley to port and a nav station to starboard with the ice box convenient to the companionway. Aft to port is a generous stateroom and to starboard is the head with a shower. Stowage is ample and near at hand in all cabins and especially so in the galley. It is rare to have so much creature comfort in a 31’ racer, and the high freeboard provides a dry ride for the crew back in the well sheltered, spacious, and conveniently laid out cockpit.

“Ondine” has a shoal draft beaver tailed cast iron keel weighing in at 2400 lbs. making for a 31’ vessel that draws a mere 4’3”. In keeping with the revolutionary designs of the 1990’s the stern sections run broad and make for a large aft stateroom to port and a large lazarette under the starboard bench in the cockpit. This vessel is fast around the cans, with a displacement of only 7500 lbs. and a combined sail area of 460 sq. ft., the SA/D ratio is over 20, Construction is solid glass for the hull with a cored deck to reduce weight topsides.

“Ondine” ghosts along in light air and really comes into its own once the breeze picks up to 10 knots. The sweet spot is in the teens, where the boat shines and easily gets into a groove with a light and well balanced helm. At 18 knots it’s time for the first reef. The main has two reefs and the roller furling genoa allows for fine tuning of the sailplan. The jib sheets are set at tight angles, close to the well inboard mounted shrouds, providing for excellent pointing. The fractional rig makes for rig tuning options to match any and all conditions. This vessel tracks well, is highly maneuverable, slices into chop without losing any momentum, and has enough righting moment to resist any gusts, translating them seamlessly into added forward progress,

The cockpit has ample combings to keep the crew dry while still providing excellent visibility forward. The cockpit is also highly ergonomic and comfortable while heeled. All lines are led aft making it unnecessary to go forward unless setting the asymmetrical spinnaker. There is a lighted compass and a custom stowable table at the binacle. Stern seats have been added for passenger seating away from all the action at the winches and wheel. The stern combing opens up to allow access to the swim ladder. Topsides feature Beneteau’s molded aggressive anti-skid surfaces and the cabin contours are gently pitched with stainless grab bars molded into the cabin top alongside the wide side decks.

Both the main and the 150% genoa are in good condition and the spinnaker, complete with dousing sock, is in very good condition. The Tides Marine mast track makes hoisting the main a breeze. The mainsheet and traveler have excellent purchase. Lewmar clutches and self-tailing winches round out

Calculations

Hull Speed
9.2 kn
Classic: 7.06 kn

Hull Speed

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.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

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

9.2 knots
Classic formula: 7.06 knots
Sail Area/Displacement
17.4
16-20: good performance

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.

Formula

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.
17.4
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
30.6
<40: less stiff, less powerful

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.

Formula

Ballast / Displacement * 100

30.63
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
147.8
100-200: light

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.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
147.81
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
16.4
<20: lightweight racing boat

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.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
16.43
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
2.2
>2.0: better suited for coastal cruising

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.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
2.19
<2: better suited for ocean passages
>2: better suited for coastal cruising

J: 10.80’/3.29m
P: 41.30’/12.59m
