Transom thickness

[Sonar]

How thick is your transom.
I was thinking for a 5.5 mtr rib
12mm grp with 2" marine plywood sandwiched onto the transom thus making
approx 14mm grp 2" ply and another 6 layers of csm and woven roven .

And carry the additional grp one meter down the hull

Any comments ar welcome.
I would rather go over the top than not enough.

Have you got that in your living room .. or do you run a massage parlour ? (for rib owners)

don't make it so think that you can't get the lugs on the outboard over it, and well done for avin a go!

From memory, mine is overall about 48mm thick - rated to 110Kg / 60Hp. Again from memory when I took the old trunks out it was Gel - glass (approx 2mm) ply (remainder) - Glass (approx 2mm) - gel (not counting the multiple layers of antifoul!)

Friend's 5.3 Ribcraft I can't quite get my Aux clamp over his, rated for something like 90 & goodness knows how many KG. Needless to say I've never bored a hole in it!

I guess a good start is to find an engine & measure the clamps.

the one I have just done for my 5.4SR is 52mm of ply and it is not looking too thick or looking like it is going to move.

Many thanks for the advise.

I have as you can see had the lipping for the top of the Transom facing inwards.
but can cut it to fit the finished thickness when done.

I have managed to pop the hull from the mould today but will have to wait for a few hands to lift it out.
I released it with Hot soapy water tipping it between the tube lip and the mould.

It near on floated away..

I'd leave the hull in the mould till you have the ribs and stringers fitted and maybe the deck, no chance of any flex then.
