measurements OK Boys, I had a chance to measure it today, so here they are. 16' long, 35 1/2" out to out of the gunwhales @ midship and 14" from the bottom of the keel to the top of the gunwhales @ midship. The keel is approx. 1/2" thick. I hope this can narrow it down but it does sound like the dims required for a prospector Dan. Andy are sure about the seats being a Chestnut trademark?? There is also a serial number stamped on the stem, but it does not seem to match any of the criteria on Dans site.
