Re: What should a Noob not tackle??
The reason tinnies are easier to repair is that for a smaller tinny, they are basically an aluminum bowl, with a plywood deck attached. If you have transom/stringer rot, just remove/unscrew the deck, slap on some new stringers or slap on some plywood for the transom from the inside, reinstall a new plywood deck, and you are good to go.
To do the same thing on a fiberglass boat involves cutting out the deck, removing foam, scraping, sanding, cleaning, and a BIG headache for fixing the transom. It is usually rotted plywood surrounded by fiberglass. So, you have to either cut the fiberglass inside the boat, or cut the top of the transom and dig it out. Then reinstall a new plywood transom, and encase it in fiberglass. Then reinstalling a new deck, and linking it to the old fiberglass. It's messy. Resin and fiberglass cloth is like tar and feathers.
All that's much more work than just bolting a new deck and piece of plywood to a tin transom.
On the other hand, aside from transom and stringer work, there's a lot that's easier on a fiberglass boat. Dings, crunches, and keel dents are all simple fiberglass repairs. It's not too difficult to make these repairs look like new.
On a tinny, pounded out dents look like pounded out dents.
USUALLY, you get a better ride from a fiberglass boat. Most tinny boats aren't too curvy. The bottom and sides are flat planes bent around a form.
Fiberglass hulls can be formed into much more elegant shapes. The bow can be flared to aim bow spray away from you on the deck. The prow can cut into the waves better. Basically, designers of a fiberglass hull can focus more on what makes a better riding boat, rather than the tin designers have to focus on what boat can be made out of flat pieces of aluminum.
Fiberglass boats are always heavier, which sux for towing or horsepower of motor needed, but makes for a much more stable ride. Tinnies are lighter, so they bob around like a cork in rough seas.
If you find a fiberglass boat with a fiberglass covered DECK (instead of carpet covering plywood), that is a big plus.
