Hi Harry,
Sorry your thread has been a little hi-jacked and drifted off-subject from your excellent Sea Raven build, but I think it started with Leaky seeing a resemblance to the Beachcomber and me thinking that the Beachcomber was a bit like a sleek Vivacity etc... and as is often the case one thing led to another - it was very interesting - but to get back to your build:-
What have you got planned for the square hatch opening in the cabin roof?
A cabin roof light, ventilator, or a space for a plug-in mast perhaps?
Looking forward to seeing it on the water!
Bob.
