Simon,
you don't say which kind of boats or ships you want to sail. There are books on just about every kind you can imagine, except classic speedboats as far as I know and that's the one I'll write one day<G>
Seriously, decide what you like to see and get a suitable book. Please, if you like scale craft, don't waste your time with a silly Springer tug or footy yacht. They'll teach you little and are hideously ugly.
If you like warships, there'll be books. If you like merchant vessels there's a book. Sailing barges, scale sail generally, R/C yachts, there's books. Buy some magazines…Model Boats or Maritime Modelling International will cover articles on umpteen types to whet your whistle and you can look for build articles on here or suitable books.
To be perfectly honest I can't watch You-tube How-Tos as the voices drive me nuts, but some can tolerate that nasal condescending tone.
If you wait for a club to help you'll be controlling the model from your wheelchair (or coffin)!! It's always best to work it out yourself with the help of books and the odd well worded enquiry on forums.
Use the best tools and materials you can possibly afford.
I recommend a simple kit to get your eye in. Vintage Model Boat Company (also known as IP Engineering) do the old and much loved Aerokits range, but laser cut and slightly updated to make them easier to knock up. Their prices are very good indeed. A quick way to a working model whilst teaching you the basics of framing up a model.
Cheers,
Martin
