The owner bought this boat in 2015
General condition and any additional information
We are Sirius boat fans. SiriusLea, what a great lake boat she is! 1987 28ft. Sirius Sailboat (Vandestadt and McGruer Ltd. (CAN) 1965 – 1987 Owen Sound) for sale in Hamilton. The Cadillac of Sirius sailboats, SiriusLea was a custom build for her first owner living and sailing out of Wiarton area on Lake Huron. Personal friends with Fraser MgGruer, one of the boat builders, the original owner appointed this boat to exemplify his position as Commodore of the local sailing club. SiriusLea has all the features, and was designed from the start to showboat the very best of Vandestadt and McGruer, boat builders among Canada’s all-time best. If you have ever used the phrase “SHOWBOAT”, SiriusLea has actually been a “SHOWBOAT”. Our first boat was a Sirius 21 swing keel, and we loved it, but what an upgrade 28’ SiriusLea has been.
SiriusLea has been a passion and working project for us since her purchase in 2015. She is presently at Hamilton Harbour Marina West. SiriusLea has been a terrific experience for us and her list of benefits is very long indeed. I will do my best to mention all them below.
Standard features
We take good care of our toys, and SiriusLea is one of our most prized possessions. Please contact me with questions. SiriusLea though, sirius offers only.
Extra gear included
Improvements to the hull, deck, rigging, engine, or interior
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)
