Boat building, maintenance, repair, and modification
Atom Voyages: Great info by James Baldwin about off-shore sailing, repair, upgrade, and modification of the cruising sailboat. He twice circumnavigated in his Person Triton Atom. His travelogues are very well written and could easily be published as a book. There is a lot of great information on this site.
Pearson Triton 381: The best site I have seen on fiberglass sailboat restoration. Detail documentation of the total restoration of a Pearson Triton and its continued maintenance. If you are considering rebuilding all, or even a part, of your boat, you would be wise to read the info contained in this very complete and detailed website. I once read Tim Lacky's website refered to the "Holy Grail" of boat restoration sites.
Jacobson Woodworking: Details the on-going work to complete a bare hull Lyle Hess 34' Falmouth Cutter. Kaj Jackobsen's woodworking skills are impressive. I visit this site when I need motivation or just to keep the bar high for what quality joinery should look like. Very nice.
Stimpson Marine: I bought the plans for the bow-roof shed from Stimpson Marine. The best $20.00 I have spent so far.
Jamestown Distributors: I buy most of my supplies from Jamestown. They are helpful and fast and generally have everything I need. With the VIP pass you get free shipping for a year.
McMaster Carr: An amazing site with about every kind of material you can think of. I buy abarsive from McMasters. I also by bronze rod and flat bar stock from MC. They are terrific folks.
The Simple Sailor: Roger Taylor's site detailing his offshore voyages on his customized junk rigged, twin keel, Coribee 21. Mingming is a very neat looking boat. Roger sails single-handed. His focus is high latitude sailing. He competes in the "Jester Challenge" TRANSLANT ocean race for boats 20-30 feet. He is truley a keep-it-simple kind of sailor. His philosophy is well thought out. His writing is clear, tight, humorous, and edgy.
