have a 1971 16' Powercat Angler/ Bull-A-Gator. They are narrow,
trihull, open boats.
They have stick steering and only two longitudinally center mounted seats.
I might add a cooler in the middle to serve as a 3rd seat/ live well. This is just a fishing boat.
My intention is only to have a safe and solid boat as quickly and cheaply.
The floor was your typical plywood covered with fiberglass but had splatter paint instead of carpet.
The floor was half rotted so I removed it. Not surprisingly, there was standing water
in there with the waterlogged foam. I have since removed the foam, but I'm still undecided on whether
to replace the foam and if so with what. I have read quite a few threads on this topic.
The 2 part foam seems the most expensive and work intensive.
I want to leave a center channel for bilge draining purposes. This boat has three stringers.
If I do use the 2 part foam, I would have to either cut out the center portion of foam or
make a barrier to keep it from filling the channel. I thought about using the foam sheets
from the Home Depot/Lowe's, but I might have to avoid styrofoam if polyester resin dissolves it.
Leaving the foam out would only leave the issue of it providing support and rigidity.
(There is more foam under the deck. I will be guess-timating volume to see if it’s adequate.)
I don't think the hull really needs help. How much does the foam contribute to floor stiffness?
1/2" thick plywood (as mentioned in Runabout Renovation) sounds rather skimpy for
floor thickness. I guess there's nothing holding me back from going to 3/4"
(and I guess the fiberglass does add to the strength/ rigidity).
I'm planning on replacing the stringers which are "mostly" good with new wood ones.
I've been reading about how people use a flowing epoxy to seal/preserve the stringers and floor.
Since I was planning on using polyester resin for the floor fiberglass, can one "seal" the stringers
with polyester resin? Is there a pre-thinned polyester resin for this purpose or should I just thin some
with acetone or mineral spirits or just use a tiny bit less hardener?
I've done polyester fiberglass layup before, but it's already been some 6-8 years, so I'm sketchy.
I didn't pay attention to/know about the chemistry. Do I understand correctly that the parts store
variety with the "wax" mixed in that floats out is adequate for my purposes?
Also, don't you need chemical resistant gloves for working with polyester resin? I didn't see
any at some of the mail order websites.
For safety purposes, I have a 3M mask with the 6001 cartridges and prefilters.
I'm also using safety goggles, not glasses for my grinding/ sanding.
OK, last question for now. I'm not sure what width of fiberglass cloth I should buy
for the floor covering. Because this boat is narrow, the floor is made with full with (4') plywood.
I imagine that I wouldn't want to attempt to apply the full width of the floor all at once.
Right? If not, I could buy a roll of 52" wide and cover the floor and still have enough
to go up the sides for good measure.
I know this is a lot of questions and I greatly appreciate responses to any small portion.
