England (Pro-Boat Marine Equipment, Ltd., a British company, list as available, all IYE parts, including the replacement wheel bearings (19mm diameter, pack of 6, part # IT - K005, $13.95 US at today's exchange rate, includes shipping), and the Nylon track end stops (part # IT - K201, $6.00). Pro-Boat also has a higher load upgrade to the original car, with 6 larger (22mm diameter) wheel bearings, that I think (verify) can be used on the original track (larger wheel bearings cannot be used with the original car). IYE "K" track, which according to their brochure is 24 mm wide and 22 mm high.

Some competitive boats rake their mast 10 degrees. Motor: Nissan 18hp electric start outboard; 15 hp Mercury, 25hp Yamaha, Waterline Strip location 38" at front compression tube 32-7/8" at shroud chain plate u-bolt 27-7/8" where the outboard edge of the canopy is 24" at the transom centerline of the rudder Stay and Diamond Tension The purpose of the diamond wires on the masts are to keep the mast in column and to prevent the center of the mast from pumping back such as in gusty conditions when you have to pop the main loose quickly. There is a mast failure in a bad pump. To adjust the diamonds you need an idea of how much mast bend your main likes for upwind sailing. Most are set to use a bend of about 4-6" when measured from a line from the mast head to the step and then forward to the back of the mast. With the forward jumper diamond loose tighten the side diamonds until you pre-bend the mast about 3-5" because it will bend a little more under a load. Then tighten the front jumper diamond until the mast straightens a little. This will help keep the mast from over bending. The forestay and sidestay tension is a lot easier. Adjust the rake of the mast to give a comfortably light weather helm. Adjust the sidestays so that the mast is vertical to the main beam. Adjust the tension so the mast rotates easily off the wind in light air. Forestay tension is now a function of mainsheet tension.
