Hi Mark,
No hull yet I am just doing a bit of practice before I start a model. I'm thinking of a PT type with a very curvy pointy bit so used some bits of balsa to mock up a bow. My efforts to date include 3 Tritons and a Sea Princess. I'm going to fit RC to the Princess over the summer to get the feel for that and then start a bigger boat over the winter.
I wasn't too bothered by having to bodge about with the bow, I just wondered if there was a more efficient way of doing the work than I had been able to think of. Taking more off then re-filling seems to be the way. Hey Ho!
