Sea Glass is a beautiful example of Phil Rhodes sloop. Long graceful overhangs and moderate beam make her very fast on the race course but easy to single hand and a wonderful cruiser. Hull is kobalt blue, new in 2020 New teak toe rail in 2020 New sails , 2018/2019 New interior cushions 2019 Full galley with running water Three burner stove with oven A really unique vertical ice box with drain to outside. New Garmin chart plotter and Garmin AIS She is well known in Casco bay and beautiful to sail and to look at. In 2021 Sea Glass received a new off shore Edson steering pedestal along with new steering chain cable assembly . New manual pump marine head with all new hoses in 2021 New Lewmar 64 self tailing two speed racing winches And two Lewmar 44 self tailing winches for single handing. New polypropylene fuel tank 2020 and the cleanest bilge in the fleet. New teak lazarette hatches 2021 Teal cocktail table matching dinette table. New stainless steel lifelines 2021 Very well maintained, clean and well loved yacht.
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)
Rhodes design #c753.
Another variant of this design, also by Cheoy Lee, was the OFFSHORE 40 or EMPIRE 40.
