Don't e-mail them. They probably just assume you are wasting their time. CALL them and tell them you are going to order a new cataraft today, and are deciding between their company, and brand X, and you would like to know how much it would cost and when it would be ready so you can make your decision. Bet you'll get great service and your boat would be on its way!
Also, if there is a local dealer in your area, just stop by and support the local guys! Guaranteed to get their attention if you are in the shop.
