We love our fleet of International 210s but after 16 years of owning them, we are consolidating to a single fleet of more “vanilla” but utilitarian Sonars.
The 210s are 30′ long and narrow double enders – Ray Hunt designs and are very classic looking, sail very fast and are easily maintained. They are light weight (2300#) and draw less than 4′.
Our fleet has slight modifications to the sail plan to enable best performance with a blade jib rather than the Class genoa. It makes for a much nicer racing boat at little loss of speed.
We have 6 equally matched fiberglass 210s that we will sell as an instant fleet for $24,000. This includes 3 top of the line 210s with lever vangs and the (unused) fast and slow genoa sheeting system. The other 3 boats are equal in speed to these but of older build. Good Fleet mains, blade jibs and spinnakers plus some good Class mains and genoas. Spare masts booms, keels, rudder, fittings. Each boat has a trailer. For comparison purposes, these boats generally sell for around $10 – $12,000. each (what we paid)
The 210 Class is still an active class and we would love to sell these excellent and beautiful boats as a Fleet. It would be a wonderful class for a Club interested in a Fleet purchase of a one design keelboat for racing and daysailing. The 210 has a long comfortable cockpit with seats. From many angles, the 210 is one of the loveliest looking classic keelboats and their performance is steady and quite fast, especially for a design from 1946.
Of course, we will sell them individually but this price is unmatched for a 6 boat group of equalized keelboats for fleet, team or match racing. There is a 7th privately owned boat also available for $3,000.
We are sad at parting with our 210 fleet as they are beautiful to see on their moorings or out sailing but the reality is that the Sonars we have are more multi purpose and we can only sustain one fleet. Such is life.
The boats are all shrink wrapped for storage as we did not launch them this year. They are immediately sailable and have proven to be excellent Club owned vessels. Photos of individual boats are available.
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)
Sometime in the late 1970’s, a company called Southcoast Boats (Oldsmar FL,USA) began making a similar model called the EXPLORER (21)??, almost certainly from the same tooling. It is thought that at least 30 of this later version were built.
