YACHT WILL RETURN TO EAST COAST USA MID-JUNE 2021
Arethusa is a Gunboat 60 like no other. It offers the ultimate multihull package and seamlessly combines luxury living with a high performance, easy-to-handle yacht.
Gunboat is known for its stylish catamarans and they are highly regarded in the industry. Since inception, the Owner and Captain have carefully developed the standard GB60 package and strived to further refine their sailing experience – and it’s paid off.
The boat is carbon fiber and its build was scrutinized to maximise weight efficiency and performance. Modifications include a custom Hall Spars rig, two Harken 990 winches on the aft deck and a redesigned forward cockpit. Carbon interior features are finished with an ultra-light veneer and high-quality appliances were installed to maintain the luxury feel.
Since its commissioning in 2015, Arethusa has appreciated upgrades to further optimise comfort, performance and safety capabilities. The highlights of these are:
2020
2019
2017
2016
Arethusa has proved itself as an outstanding live aboard for extensive periods whilst cruising throughout New England, Caribbean, Bahamas and New Zealand. It also has a minimum draught of 3.5ft making anchoring in beautiful, shallow waters hassle free.
Entertaining friends & family is effortless with its large aft deck lounge area, homely open plan dining and four spacious guest cabins. Those who have sailed her affectionately like to tell upon the stories of brunch and cocktails at 20 knots!
The boat can be quickly switched into regatta or delivery mode where 260-mile days are easily achievable. In the absence of wind, the twin 55HP Yanmar engines will motor comfortably at 9.5kts in flat water.
Kept in superb condition and meticulously maintained by professional crew; no expense has been spared to perfect the workings of this boat.
Arethusa is currently awaiting the ship to return from New Zealand where she is headed back to Newport, RI for a Summer of more enjoyment.

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
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
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
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
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)
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)
