David Mack Posted March 18, 2017 Report Share Posted March 18, 2017 What insulation have you got on the inside of the hull sides and cabin? Link to comment Share on other sites More sharing options...

Personally I wouldn't use anything that would require me to wreck the boards if I ever needed access behind them. Lots of ways to fix t&g - clips that hold the boards invisibly, secret nailing through the tongue, a batten along the floor and a screw in a cup at the top...

Neil2 Posted March 19, 2017 Report Share Posted March 19, 2017 T&G wouldn't be many people's choice these days, especially up to the gunnels, I suspect most would choose plywood which apart from anything else would be easier to fit. Is there some particular reason why you want to fit T&G? I'd agree use glue sparingly, far too many boats are fitted out with no thought given to how dismantle the interior should the need arise. As regards the paint, for a start I would make that your absolute priority. How many times do you see a guy working away feverishly on the inside of a boat whilst the grey primed cabin is rusting away nicely. It's going to be a lot harder to deal with eventually if you put it off now. I'm not an expert but I can't see why anything would react adversely with grey primer. I'd give it an undercoat and a top coat for now and that should buy you time to get on with the inside. Follow Rylards instructions on surface preparation.

Murflynn Posted March 19, 2017 Report Share Posted March 19, 2017 T&G will always tend to warp, especially in a boat where it may get damp, and hot & cold, and it is not helped if it is well sealed with paint or varnish on the face and less so on the back. It will need secure fixing to prevent this. Link to comment Share on other sites More sharing options...
Keeping Up Posted March 19, 2017 Report Share Posted March 19, 2017 After just 25 years our T&G hasn't yet begun to warp. We have polystyrene sheets for insulation. Our boat builder told us the secret is to avoid pushing the tongues too far into the grooves so that there is room for each board to expand and contract freely.

This is fine if it has a fairly neutral finish, and the gaps that exist when it is at its most contracted don't look noticeably different to the rest of the boards. However I have seen boats where the T&G has been painted on the main surfaces, but as the tongues become exposed they are not. Frankly that tends to look bloody awful!

WotEver Posted March 19, 2017 Report Share Posted March 19, 2017 Quite a few years ago my local pub had a tart-up done by the brewery. They had a pile of t&g to go around the top of the bar and some cans of dark brown stain. I said to the landlord "I hope they stain that before they put it up". He told me that he was sure they knew what they were doing as they do it for a living. Three months later he had lovely narrow pale stripes down all his dark stained t&g. I used to love the stuff in the 70's and 80's but always stained and varnished it before fitting it. Link to comment Share on other sites More sharing options...
Neil Smith Posted March 19, 2017 Report Share Posted March 19, 2017 I used panel wipe on the primer before painting, its cheap from car paint suppliers or ebay. Neil Link to comment Share on other sites More sharing options...
chubby Posted March 20, 2017 Report Share Posted March 20, 2017 Two years ago i fitted the entire cabin of my boat with T&G below the gunnells / gunwhales / gunwales ( the spelling police are everywhere) . I love it , old fashioned or not . Its " boaty " to me . I want to live in a boat not a 6 ft wide tube shaped apartment . A ballache to fit tho & it took 3 months part time to do . Stained , 2 coats of satin varnish front & back and then fitted on top of the existing ply . All put up with brass screws and cups ... even more old fashioned. If i need to take it down its a doddle. If i say so myself & self praise is no praise in my book it does look good as i got obsessive about about it being done right . Very please with it and tho it has expanded a bit theres no dreaded pale bits of tongue exposed as it was all stained etc before going up .
