Omega is very sea worthy. She sails with a boom gallows which in addition to stabilizing the rig under sail is a great safety feature because when the boom is locked down it effectively creates a rigid tripod structure across the top of the cockpit. There’s a removable inner fore stay with supporting running back stays flying a storm jib which, with two reefs in the main, can sail and point the boat in 40 knots of air. The engine has been rebuilt and updated and is very reliable and powerful. Ive been sailing Omega for eighteen years mainly on Lake St. Clair day sails but for the past three years Ive been taking the boat for extended (two or three week) cruises in Northern Lake Huron, the North Channel, and Georgian Bay. Shes almost 40 years old but still looks good and needs a new master.
Equipment: A survey is available upon request. But in preparation for my Norther Lake Huron sailing I have: pulled the engine and replaced all seals. new carburetor, water pump, fuel pump, thermostat, oil pressure sensor, dripless shaft seal. All new running rigging (not the main sheet). Rebuilt deck box and updated propane tanks. New autohelm. Recent batteries. Brand new canvass winter storage cover. Boat has its own cradle. New Radio. Rebuilt depth gauge. New battery charger. New 120 volt power inverter. There’s a two burner gimballed oven.
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)
Early models were fitted with a Graymarine Gas Engine.
Keel/CB version
BU: 3.3’/1.0m BD:5.8’/1.77m
(listed dimensions for tall rig).
(Shorter rig: I=34.16’/10.41m P=29.16’/8.89m)
The later BRISTOL 30 is very similar, with an updated coachroof.
