After recently moving home, lucky enough to be mortgage free

and almost 50 years young I thought I could do with a hobby, but what have I done ???? An impulse ebay purchase but yet to be delivered is a 46" long Birchwood and Cabin (which doesn't mean much to me but I liked the
Cruise look of it) I'm hoping it is a suitable Hull to be electric powered. HELP !!!! Where do I start ??
As far as I'm aware it's an empty hull & deck. Any advice of where to start and what to fit will be greatly appreciated. It is a long term project, so no real reasonable money limit, I'd rather fit reliable equipment once.
I realise it's a large boat for an absolute beginner (you should have seen my Wifes face

) but I thought it wouldn't be so fiddly.
Anyway, I've taken the plunge and all comments & advice will be taken on board (all puns intended

)
Many Years of Thanks In Advance.
