I completed the prospector 17,5 last year. I came at 65 lbs with the third seat, knee pads and flotation bags. I was aiming for a similar weight than the Nova Craft prospector. This winter I finished a BI prospector 14 (same shape as the Swift prospector 14) at 40lbs (including removable yoke, flotation bag and knee pads and kevlar prospector 14 at 29,5 lbs. I didn't take the take to fully complete the current thread, I will probably do if I had some spare time.
