After chatting with Dave at XT I took a gamble and ordered a Baja 278 cover for my sport 250 and the thing fit great. it is supposed to be a trailerable cover but I think it needs some modifications in order to do that. we tried it hitting rain leaving LOTO and had to strap the cockpit down. it still needs a adjustable support to make sure water stays off when storing. the cleat holes do not line up but are in spots that I want to add pop up cleats anyways so that may work out good on my side. the gas fill opening also does not line up. very happy with it!
