Kind of depends on where you're at, skill wise. If you're a complete beginner, go to the library and go through their books on basic carpentry, find a couple that are simple and you can understand. Take them home and read them and then start with some simple projects around the house, book shelves and stuff. As your confidence and skills grow, start thinking about what you want to do with your boat and take on some simple projects there.
There's lots of sources on-line, Wooden Boat sometimes has interesting informative articles on various boat related projects, and there are other on line magazines as well. Google'em.
You'll probably be doing some glass work as well, Gougeon Brothers website has a lot of information about using epoxies; a lot of the information is relevant to polyester resins, but there are differences you need to be aware of, so
Google is your friend here too.
YouTube has loads of videos on everything under the sun, but you have to be careful, a lot the people producing them have strange ideas on the right way of doing things. Some are pretty damn good though...
CF has some good construction threads, too. Learn to use the 'search' function, you can sometimes narrow down the results by putting quotation marks around the relevant phrase.
Tools are important, good ones make the job fun, bad ones are a constant source of irritation and inefficiency. You can sometimes find good deals on used ones from craig's list (often at garage sales rather than in the 'tool' section). Probably the ones I use most are a cordless drill, an oscillating
sabre saw, a 4 1/2" grinder, a 10" drill press, a heavy duty
electric DA sander and a table saw. Brand is a bit more idiosyncratic; I like Dewalt, Milwaukie, Bosch, Rigid, Hitachi but have a host of other manufacturers tools as well.
And finally materials. First, don't throw anything you take off your boat away. If it's interior
wood, you may need it as a pattern, and it's likely to be mahogany or teak, which are very expensive. You never know what you might use it for...
Also, try and stay away from 'marine' suppliers. There are plenty of woods, exotic and otherwise, that can be used on the interior of a boat, that are available from the residential and
commercial flooring markets and such. Keep you eyes open, what is plenty for your needs may be just scrap for a
commercial contractor...
Always like to show these pictures, got this
wood from the reject pile from Home Depot for .50 per 4'x4'x1/4" sheet. Bought all ten for 5.00, used it with a 1/2"
plywood core to make all the bulkheads and much of the cabinetwork for my boat. Far as I can tell I think it's called (obviously I guess) bloodwood.
