Found a 1994 16' Sea Nymph with a 25 Evin that I want to buy for a fishing rig. I noticed when I was looking at it - it's only rated for 4 person/600lb. We typically go with three of us and we are over 600 total with no gear and like a 1000 geared out with anchors, seats and stuff. Are these numbers conservative or is that the max? I weight about 165, my dad about 280 and my brother about 290. Should we keep looking or what? Seems a little low for a 16'?
