Fast, powerful and agile. PRICED TO SELL!
The IC is a unique class of boat and is one of the fastest and most efficient single-handed monohulls in existence. It has a low displacement length ratio, which gives it a high hull speed and a smooth transition to planning. It also has a sliding seat that allows the sailor to hike further outboard than with a trapeze or racks, balancing the power of the sail and reducing the drag of the hull. The result is a boat that can go upwind fast and downwind like a rocket.
This particular boat is USA 195, named “SIREN”. It’s a Nethercott one design built by IC legends, Del Olsen and Fran De Faymoreau in the 1990s. Glass and foam hull. Carbon mast and boom. Classic west coast carbon sliding seat and carriage.
It also has an AMAZING community of passionate sailors who share a love for sailing, adventure and innovation. The North American International Canoe Class is active on both the West and East coasts; led by president Will Clark, this community will eagerly welcome you, as they did me, and help you every step along the way. The sailors on the West Coast plan a meetup a couple of times a year in Point Richmond for a great weekend of skill building and sailing on the SF Bay.
Sails and dolly included. Ready to race. 2nd photo is a stock photograph so you can get a sense for how it sails.
Equipment: Carbon Mast, Carbon Boom, Sails, dolly, trailer negotiable.
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)
Single handed development class. Measurements are max values.
Most early boats had 2 masts.
Sliding seat:
The sliding seat was first used sometime during the 1880s.
It was subsequently banned and later allowed.
Todays limitiation for sliding seat:
Horizontal extension from centreline of hull: 2040 mm max.
Max. width: 500 mm
Max. mass: 12 kg
Min. mass: 9 kg
The 10 sq meter limitation first established during 1930s?
The drawing depicts a version from the mid 1960’s.
