Mechanical Failure

[Fish 0]

I was worried that her shearline looked severely hogged which is a worrying sign in a boat of that type.

What does that mean waikiore?

hogged?

interesting article to glass or not carvel.

Allan also discusses the merits of light glass cloth over carvel planked hulls in the book. His advice: DON’T

[rossd 16]

Why I thought it had been glassed was reading reports at the time and one from an “expert” in the US who knew the yacht said in his opinion the reason it disappeared was because it had been thin glassed. Someone above said they looked at the hull and could see the plank outlines, that doesn’t necessarily mean it wasn’t glassed as planks would show through glass anyway especially after a few years.

I once sailed in a little wooden boat that someone had glassed over so heavily that it sank. There was no buoyancy left.

Didnt really sail it then? More kind of.......sunk.????

[Kevin McCready 83]

It was an Enterprise dinghy and sailed sluggishly until a capsize. It would have been better left to form a nice little reef but it sank in shallow water and the owner wanted to retrieve it.

Would you not need to spline the joints before glassing ? that would help to reduce the amount of movement which as observed otherwise will defeat the purpose of glassing. I have also heard of people future proofing classic carvel boats by doing a double diagonal cold moulded skin over the planking.

[waikiore 400]

Yes Frank that is the only way it will last, after first drying the hull thoroughly inside and out and splining her, glued up tight  you can skin them with one or more layers diagonal before glassing, we started this in the early eighties up north on a Falmouth Quay punt called Curlew that some of you may recall bailing her way here. Well after many years at the Falklands she is I believe in the Falmouth Maritime museum still tight as.

Curlew was epoxy coated with no fibreglass cloth after the application of 3 skins of glued kauri.

 

[Priscilla II 392]

From memory Curlew required quite a bit of restorative work once gifted to the Cornwall Maritime Museum.

Maybe due to the lack of sheathing cloth to act as a barrier.

Yes the glass is really for abrasion resistance after that process -certainly not required for strength.

Is carvel, a single layer of blanks molded to a skeleton/frame ? 

[erice 732]

 hull planks are laid edge to edge and fastened to a robust frame, thereby forming a smooth surface. Traditionally the planks are neither attached to, nor slotted into, each other, having only a caulking sealant between the planks to keep water out. Modern carvel builders may attach the planks to each other with glues and fixings
