Experienced paddlers don't put "fast" and "15 feet" in the same sentence. A 15 footer will only be "fast" if the paddler has been pumping iron like Arnold. And even Arnold may get passed by a non-iron pumping kid in a 17 or 18 foot boat. It takes a longish waterline to get into the fast category. And some of the boats mentioned are, for the same reason, narrow. I wouldn't characterize a boat under 20 inches wide as "roomy" if by roomy you mean room to move your kester around. You have to decide which of contradictory characteristics you've got to have and which you can dispence with. A hull 15' x 24" should be a pleasant paddle and fast enough but not real fast.

: The SeaTour is also nice and I saw there is a 15' version.

: Actually I am seeking a roomy, fast and good tracking boat but not
: much longer than 15' .
