Marine Ply for Bulkhead Glasgow

[sundanceoflorn]

I am replacing a bulkhead which currently has 15mm ply tabbed to the hull and 6mm veneered ply either side. Am intending to use same thicknesses and veneer myself having seen other posts on how to do this.

Its an internal bulkhead forward of the galley. Only on port side and extends up to the deck. I plan to epoxy the edges.

Have been searching for somewhere local to Glasgow to get good quality marine ply in these sizes. Builders merchants tend to have 18mm and not sure quality.

Anyone know a local supplier?

I have also been looking at other suppliers that do have these sizes for delivery such as the below but don't know quality even if states BS 1088.

I have looked at Robbins but is quite a bit more expensive.

Gilmour & Aitken, near Dumbarton might be able to help, call them and ask.

For quality assurance you may have to buy a Lloyds, DNV or ABS approved marine ply which has a degree of manufacturing assurance before being approved by the certifying authority, but then the price goes up.

Alternatively any so called marine ply to BS1088 will do for internal work, suitable treated and then bonded in place.

Another option is to contact A&R Way, Lochgilphead who is a reputable and skilled wooden boat builder, has done a lot of repairs for me and bought in ply for structural bulkhead work. They will know where to buy plywood that suits your needs.

Have you considered veneered foam.

Hey thanks will try these guys. Otherwise one of the BS1088 ones. I will coat with epoxy and am tabbing to hull.

Have you considered veneered foam.

Jonathan

No but sounds interesting - I was planning to use the paper backed Sapele or Teak veneer from Wood Veneer Hub.

Veneer

is that closed cell foam (hard) or the foam that is used to back headlining vinyl?

The bulkhead is likely to be structural, and needs to be able to take compressive loads in the plane of the bulkhead. Would a foam core provide strength to take such loads? My instinct is that it wouldn't.

I don't know as I don't know what the current bulkhead is manufactured from.

But glassed foam with a wood veneer is an optional product.

If I were replacing a bulkhead I would not be looking at suppliers for marine ply - I'd initially look at options - then I'd look at suppliers. Most suppliers of glassed foam will be happy to offer advice on their product - its a common place application.

I have just used this stuff:

Teak Veneer Sheet (Florida) Flexible Veneer Sheets- Back Fleeced- 2500mm x 640mm | eBay UK

and am pleased with it, good delivery etc.
I am sure your 1088 timber will be fine, in fact other cheaper ply alternatives can be very good. I found an original bulkhead made from veneered blockboard which must be one of the most unsuitable things you can imagine for the job.

To ensure agood bond I have seen holes cut in the ply and the tabbing go though thus avoiding delamination although with epoxy there is more of a griponthe ply

Had a look - is Coosa the type of board you mean?

No chance of rot and reduction in weight are definitely appealing but I suspect would be more expensive (no prices there). Also recommends to enclose in fibreglass which adds weight and cost.

Very interesting though - have you used it or similar product?

The current bulkhead is tabbed along a vertical stringer on the hull. Boat is 35 years old

The veneered 6mm ply either side of the 15mm I think will be to cover the tabbing rather than have the full 27mm as one piece of ply

'Home' boat building, largely or exclusively large blue water multihulls, is big business here in Australia and a whole industry have developed to service it. Schionning and Grainger (google them) are market leaders and Schionning will sell you a whole kit, plans, CNC precut coated board, resins etc etc.

Duflex is one of the brands, https://atlcomposites.com.au/icart/products/92/images/main/Duflex Brochure.pdf and they are used structurally, bulkheads, (and for internal fit out).

The glassed versions come with a peel coat, negating the need to de-wax and sand. There are custom boat builder in the UK, I only recall John Corby - but there must be others - and there will be an industry supporting their needs, which might include Duflex or alternatives. I know Duflex is available in Germany - maybe also the UK (or alternative products)

I've not used the boards, but have sailed on an 11m and 15m Schionning built from them (and watched professionals here using them). If you look at the Schionning website they detail usage which will give you an idea - and the confidence that its 'common place' the panels are structural (Schionning blue water cats are not reported to break up).

I have worked with simple foam panels and Bainbridge was my source, their office and warehouse are 3km away. There are other, slightly less convenient - but they are local businesses - a bit far for you.

I did consider building a cat but I discovered, through observation and comment from those that did build their own, that building is the easy part, fairing is the killer. But I researched hence my suggestion

It’s also possible to lay up your own glass/foam/glass, maybe incorporating other materials as needed. Your choice of resin too. I’ve done this, on a previous boat. It was still in use 24 years later when I last looked

Thanks all for suggestions. Gilmour & Aitken were able to supply the ply at good cost and deliver so am going for that.

Thanks will check that out as sounds like fleece backed is better than paper backed.

I have ordered some samples to see if Sapele or Teak veneer is better match for rest of boat. I've always thought it was teak but not so sure now. Its a Tyler 34 fitted out by Sadler yachts around 1990.
