My interest is only in the ability to sail in 6" of water.

Is that one of those things you lay in and clamp a big gun on the foredeck full of nails and scrap metal?

Thanks for all the reply's. A lot of good, useful information.

So to fill in some of the blanks.

The boat in question is a new build, but something that will probably spend most of its life hanging in the roof of the garage.

Its a variation on a West Mersia Duckpunt, made famous by the exploits of Dylon Winter.

Mines made of a thinner ply but I've added buoyancy tanks front and rear to add a little stiffness but more importantly some safety for when I am bobbing up and down on the Medway.

Based on everyone's comments I'm going to seal it all with the pond sealer (see separate thread) and then use the Sikaflex to fillet with. The fillets don't need to be big but I want to seal all the odd gaps to make it look better and to reduce the number of places water can seep into and rot.

I'll let you know how it works out

A trade polyurethane sealant will be a fraction of the cost of marine sikaflex.
How big does the fillet need to be though?
Epoxy goes a long way.
With sikaflex, you will need to prime with poly varnish or something?

I would have thought that Sikaflex DC, whewre the DC stands for Deck Caulking was pretty obviously designed for caulking?  And like tick says, it depends what you want.  No point putting lipstick on a pig. 
the same, but different...

I suppose that the purpose of the restoration is the important thing. I 'restored' an old Merlin that was beyond restoration just to get it sailing again. It took me about 2 months and cost about £40.00 rather than years and £1000's. We had good fun. Oddly enough the original owners son bought it off me for sentimental reasons for £500. I did however recommend that he did not take it out in anything above an F3! A better outcome than it rotting in a garden in Barrow in Furness.

I'd suggest that pretty much anything other than an epoxy/microballons mix is going to create a water trap timebomb and potentially cause far more problems costing more money than is saved by not using epoxy in the first place.

Stoppers such as P38 are too brittle and will crack letting in water. Bathroom sealant will shrink and fall off, Sikkaflex or other PU adhesive will fare better but is simply not designed for this job and I wouldn't use it.

I'd go for P38 car body filler cheap and very paintable

I would use sika flex, without a doubt, though you could just use plastic padding marine filler, it won't last forever, but it will do what you want.
