Thanks for your quick reply Pete!

I am glad that this sort of thing has been done before!

How much was chopped from the stern of your boat?

How was the stern sealed? With fibreglass sheet?

I'm not too bothered about straight line efficiency, so long as it
floats, that's the main thing and making it short enough for easier
storage.

Our local river is overgrown in places so having a shorter boat will
help when avoiding fallen branches etc.

Thanks very much,

Nick
