I don't know of any rental outfits on Cape Cod. However, google search found this dealer on the Cape http://www.sturgisboatworks.com/ You should call and ask if they know of any rental shops on the Cape. Likely they would know as they probably sell them their boats and parts. Sturgis does a lot of race boat chartering (pristine, competitive Lasers are a specialty of theirs) so if they offer to rent you a boat themselves at a high price, you might want to press them for a cheaper alternative.
