Tired of pumping up your tires every time you go sailing, or those wobbly wheels with broken plastic bearings? Unable to find Sunfish dolly wheels at a reasonable price or that weren't on constant back order, I sourced wheels directly from the manufacturer and now have a supply of them. Now available on my site www.boatwheelz.com or on eBay, just search 'seitech wheel', currently item number 280855131318. Cost is just $70 a pair! These are not Seitech brand, but are a high quality replacement. They are a slightly larger diameter than 'A' wheels - 15.5 inch diameter, 4 inch width. When you order, you get the entire assembly - wheel, tire and nylon bearing. These wheels will fit any dolly that I am aware of that uses a 1 inch axle. I've had them on Seitech and OptiParts, will also fit Intensity Sails dollies. These would also be a great for anyone building their own dolly! I've had an ad on the Laser forum for a few weeks and have a number of happy customers that have ordered.
