Speaking of the ladder, is there
a maximum weight rating on the ladder? I don't see
anything on my new Bayliner 175 Capi, and wondered
about that. My new bright Orange fiberglass work
ladder that I got at Home Depot has max weight
warnings all over it, and at 210 myself, I'm close to
that limit without tools/equipment etc. so I dunno.

According to the dealer the ladder/platform on my SeaPro is 350
pounds. The salesman weighs 310 and says it holds him with no problem.
As to your Home Depot ladder you can bet it will hold considerably
more than its rated capacity. They rate them conservatively due to
liability suits.
