Seller's Description

‘Sea Bunny’ is the original (Rassy/Enderlein), sloop rigged, version of the popular GRP long-distance cruising HR42 marque and has successfully completed two circumnavigations. The second of these, with us, was mostly two-handed and covered over 60,000 nautical miles.

She is for sale with much regret as we now feel that we have reached a stage in our lives when long-distance cruising is behind us. ‘Sea Bunny’ is well equipped for ocean cruising but is equally at home in local waters.

She is well equipped for cruising with solar cells, 2 wind generators, sprayhood, bimini and cockpit closure, watermaker, Raymarine chartplotter, radar and fishfinder, HF/MF marine band radio, heating, large domestic battery bank, 2kVA inverter, even air conditioning for those maintenance or R&R stops in tropical marinas!

GRP moulded hull and deck with encapsulated iron ballast in long fin keel, rudder supported by 3/4 depth skeg. Sacrificial shoe fitted to lower part of keel and wire from keel to skeg. Teak covering on deck replaced 2009 (Thailand). Topsides repainted 2016/17 in Trinidad (except blue stripe - 2012 in Thailand). Coppercoat antifoul system applied 2012 (Thailand), touched up 2017 (Trinidad).

Extensive refits undertaken in 1997 (by previous owner), 2001 (UK), 2009 and 2012 (Thailand) and Trinidad 2016/7.

Rig: Forestay replaced 2014, remainder of standing rig replaced 2016

‘Sea Bunny’ is currently berthed in Plymouth, UK.

Calculations

Hull Speed
8.8 kn
Classic: 8.26 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

8.76 knots
Classic formula: 8.26 knots
Sail Area/Displacement
16.0
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.
16.01
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
40.0
>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.

Formula

Ballast / Displacement * 100

40.0
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
287.1
275-350: heavy

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
287.07
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
39.1
30-40: moderate bluewater cruising 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
39.11
<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
1.7
<2.0: better suited for ocean passages

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
1.73
<2: better suited for ocean passages
>2: better suited for coastal cruising
