Seller's Description

In water in East Hampton. Needs nothing as we are sailing her currently, but getting ready to change boats. Allison Rose is a solid and comfortable boat with lots of room in the cockpit and below. She is in a slip in Three Mile Harbor, and the owners have a mooring in Three Mile as well, and this can be made available for a few weeks to any purchaser who wants to take advantage of some of the summer in East Hampton.

Equipment: Universal M25XP Diesel 417 hours always yard-maintained. New in 2023 shaft, coupling, stuffing box, cutlass bearing, prop, motor mounts. New in 2021 Exhaust Riser and hoses, new heat exchanger. Engine is solid and reliable. Rig: Standard height rig, full batten main, 110 genoa, 150 tri-radial genoa (stained, but a big powerful sail) Symmetrical spinnaker and ATN Spinnaker Tacker and sock (spinnaker rides in collar round furled headsail and behaves more like an asymmetrical). Rigid vang and full traveler, all lines to cockpit. Lewmar winches. Updated Hood/Pompanette 808 roller furler installed 2017

Hull: This is the full keel 34 with a keel-stepped mast, and so stable and solid feeling, and a great sailing boat. In 2020 the bottom was taken down and new barrier coat and blister repair done and ablative bottom paint used. The paint will last through the 2024 season. The boat has a deep elliptical rudder, which was an upgrade when she was ordered new by the original owner.

Electronics: New Xantrex Freedom HFS Interter Charger installed 2019 Blue Sea battery switch and starting battery isolator Two deep cycle house batteries and two starting batteries New 2020 Standard Horizon GX1600 Explorer radio New 2020 Sony Stereo with new speakers in cabin and in cockpit New in 2018 Raymarine electronics. E125 12.5 touchscreen chartplotter, masthead wind direction and speed with dedicated display and integration with chartplotter, depth with separate display and integrated, speed and water temp integrated with chartplotter, rudder position. Raymarine autopilot. This is older generation and thus standalone and not integrated with the chartplotter. Controls in cockpit

Galley: Hot and cold pressurized water, two-burner gas stove / oven, sink evacuation pump, ice chest, older 110 fridge in aft cabin.

Saloon: Cushions clean and in great shape. Custom teak saloon table, slightly smaller than original to provide more room when seated. Original table will be provided as well. Table on telescoping mount and drops to make saloon seating to large sleeping berth.

Head: Composting toilet installed 2020. Two urine bottles for switching out. Sink and faucet with hose sprayer for wet shower use.

Topsides: New California (tall) style dodger and canvas, connector to bimini for continuous canvas over cockpit to transom. Very large cockpit for the size boat. Vinyl cockpit cushions. Custom stern rail. The original rails on these boats are one piece with a crossbar. This is a custom designed two-piece rail for easier walkthrough to the transom. On top of the swim ladder there is a small custom teak step (the worlds smallest swim platform, small but very handy.) Dyneema lifelines with CS Johnson fittings. All stanchions were removed and rebedded with butyl rubber which provides for a very dry boat.

Hull Speed
8.7 kn
Classic: 7.32 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.


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

8.67 knots
Classic formula: 7.32 knots
Sail Area/Displacement
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.


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.
<16: under powered
16-20: good performance
>20: high performance
>40: stiffer, more 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.


Ballast / Displacement * 100

<40: less stiff, less powerful
>40: stiffer, more powerful
200-275: moderate

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
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
20-30: coastal cruiser

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 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
<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
>2.0: 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.


CSV = Beam ÷ ³√(D / 64)

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