Structural Question Sceptre / Tsunami

[abl1111]

I was wondering how the(3) parts of a Sceptre / Tsunami are actually connected.

The liner is attached to the hull how and where exactly ? I 'assume' that it's held to the stringers by Potter Putty ( 'ASS'UME the operative word ). What other areas hold the liner in place ?

I'd like to see some pix of what this looks like. And, to see where the stringers are exactly.

Then, how is the top cap connected ? Are the liner, top cap and hull all screwed together at the gunnel / ( I thru-bolted mine ).

What gives these three parts strength and rigidity ?

Thx

The inner liner is 'glued' to the tops of the stringers and around the top edge to the hull with Potter putty - that top edge is where you through bolted your cap on. The Sceptre cap also includes the helm areas which meeet the liner about 6" off of the deck.There are several threads here that have pics of the stringer tops and there is also a pic of the components that show stringers and liner for a SF in one of the brochures on the literature page. Basically the strength and rigidity come from the various box structures formed by hull, stringers, deck, and cap.

I would like to know if anyone has done work to make the hull, liner, and top more solid ? I find how the topside and liner meet, especially near the 6" helm 'joint' to need improvement.

Also, where would you think the forward stringers correlate with the liner in the cabin - the storage compartments ?

AARRRRR, Tommy, me boy you'er right. He should either be flogged with the cat 'o nine tails, keel hauled or worst yet made to listen to another Hillary speech. (Does she sound like a goose honking or is that just my tinnitus? Probably just take some getting used to)

Gentlemen, gentlemen, calm yourselves. Its gospel that Carl designed and built incredible hulls and Potter pretty much continued that legacy, but, and I hate to say it, Potter was not "without sin". He made a major screwup in building the 25 Seafari. It ain't got enough bulkheads. That one bit me hard, lucky I did not sink. Course, it took the best part of 40 years of banging around to show up, so maybe it wasn't all that bad, but I'm still bit.

abl1111,

Check out the thread "Fishtank aka The Beast" thread in the repairs section; there are several pictures of his 23 Tsunami with the deck removed that may answer your questions. I've got he same boat and am finding a ton of useful information in those pictures.

[abl1111]

Water Rat - that was a very helpful link - there was a pix that showed me what I was looking for. I am surprised the only thing holding the liner to the hull is potter putty
9 and as you mentioned, the hull: liner and the rubrail.

After years of use, that putty has to start to fail. For example, the putty at that 6" liner:topside seam on my boat is not holding anything - it acts more like a spacer than anything.

Is there anyone who thinks it's a bad idea to glass that seam up ? To make the topside and liner - 'one' at that 6" high spot.

[abl1111]

Gents - would like some advice on my plans for my 23' Tsunami. I want to glass the seam that connects the topside to the hull near the helm and the passenger area - it;s about 6" off the floor and is covered by teak trim.
