For sale is Maia, a 1979 Gulfstar 37. She has been under her current ownership since 2014 and has had extensive work done to her as well as numerous upgrades. Primarily sailed on the Maine coast, she is in great shape and ready to go. Previous owners sailed her to the Bahamas and indeed she is the perfect vessel for those waters as her 4 6 draft gives her easy access to many anchorages. Serious inquiries will receive a complete list of completed work. This is a partial list: New primary Lewmar self tailing winches New Lemar vertical windlass All standing rigging replaced 2024 Chainplates pulled and rebedded All stanchions and lifelines replaced 2024 All new opening portlights 2024 Maia is very well behaved in heavy air and in spite of her sturdy build she does well in light air. A large cockpit affords plenty of room for guests and crew. She comes with a new Harken furler as well as a stack pack making sail handling a breeze. Currently stored inside on the Coast of Maine until spring she can be viewed by appointment. Please contact me via email only.

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)
