Hi My name is John , 66 years young and from the UK .I was in the Forces  therefore a lover of aircraft , tried modelling them which was OK but flying them was a not so good , so went back to boats .I started this Director class paddle boat (Forcefull) 15 years ago so I thought is about time to finish it .     John                                                                                                                               

Welcome John,
If I recall, there are a couple of threads on here which address you question.
Will have a search for you when I get home.
How about some photos of your boat
cheers
