Accounting for slight roof angle with chimney collar

[Ray T]

Had a local boat yard make a collar for me out of hardwood. I gave them the dimensions and spec. required.

 

 

Another example found on the web.

Procast near retford made me an angled collar some years ago for my convex roof.

Some chandlers sell them. I know Uxbridge boat centre do.

Almost certainly yes. Either you, a friend, or pay some one. It will be custom for your boat. Too small a market and too many variables for anything off the shelf.

 

I've seen them on the shelf at UBC.

Looking at this, I'm more pleased than I thought with my neat flat collar and slightly jaunty chimey angle!
