Welcome Berny. If you are looking for some helpful info, than you have come to the right place. Any technical information you may want on restoration, search nearly any post from HG02. There is also a member here restoring a Redwitch that will in time have plenty of good information.
As for sailing info... There are a lot of people on this site whom have learnt to sail (not assuming your a newbie to sailing) by asking many of the right questions here.
It is not a bad place to be when you have the spare time.......... Or don't have the time but cant be @rsed doing whatever it is your meant to be doing
