seacast for transom
 

If you wan't to build boats and you wan't to use something else then wood for the transom. Would a product called seacast help you.

btw : what is seacast ?

its basically polyester resin with fillers


I would not use it, for many reasons.

Its a short cut, I do not recommend short cuts. :)

I don't like taking shortcuts either man, as the saying goes;
The short way is often the long way.

Her is an off topic question,
19 ft boats, why aren't they made with open transoms anymore and why have don't they use outboards with a 20'' shaft lengt anymore ?

Too many floaters.

Q about seacast. Would you like it better if it were a vinyl ester or epoxy matrix?

Thought Sailfish used it in transoms , but that is new not secondary.

First awnser: so it's because there are to many boats with an open transom?

Second awnser: I have no idea what vinyl ester or epoxy matrix is.

New Q: So why don't 19 footers have a transom lengt of 20 inches ?

I'm prefer to look at Seacast as an transom replacement option. Done properly, I think there is enough documentation to consider it viable. Are there risks? Yes. A suspect bond is very possible if the adjoining skins are contaminated. It's polyester which offers less adhesion than vinyl-ester or epoxy.

There are still plenty of 19 foot boats with a 20" transom, mostly lake oriented runabouts or speed boats. But off shore, 25" transom is much safer. I think GFS' reference to floaters was re tragic deaths, not too many boats.

Back in the day of the 20" shaft, the motors were 25% lighter. A 115 from the 80s was 300 lbs now they are 400lbs. Ask mitchman or anyone on the board with a SeaCraft 20 that has a 20" transom how they really feel about it. Once water comes over the transom, it keeps coming. As soon as I can I'll be raising mine and getting a shaft extension or a 25" motor. Many guys have already added a splashwell well or enclosed the transom and added a bracket.

The only open transom I feel safe in is a mid 80s Boston Whaler Revenge 20 WT, but I come home black and blue every time I go out in it...

Ok I understand, thanks man but about the 20 ft whaler.
I have an uncle with an old 70's 19 foot mako.
His is a 20'' lengt with open transom.
I have found it one of the fun filling boats ever and we have never had any problems with water coming over the transom.

The old Mako 19s were fine rugged boats. And very stable fishing rigs. Those were about 12 degrees at the transom. They also had a an 8ft beam. For these reasons they floated high and the transom was not as easily overcome by water from from behind. A 20" shaft did not ride as low as with a deeper v because of less dead rise and more beam. They were also filled with foam and that often led to fuel tank failure and early rot if holes were not properly sealed.

My confidence in the whaler is only in the fact that it has a ton of flotation.

Regardless, they both ride like crap when compared to the narrow beam and variable dead rise presented in the SeaCraft 20s.;)

Balance is not over rated.

Happy Haloween my seacraft Ghosts.
