A resource for sailing, yes.
A resource for fund raising? No.
Fund raising is quite an art, everyone is asking for dollars. And you're not going to see many of them unless you start a 501-c-3 formal not-for-profit corporation, or find one to sponsor your trip and accept the donations.
Then there's the question of whether your expensive trip is going to be a more effective fundraiser than something simple, like canoeing from Maine to Oregon.
If you want to sail around the world, that's one thing. If you want to raise money for a good cause--do that research first, then ask yourself if the sailing project is the right or wrong way to do that. There are plenty of regattas and races and other special events for charity. Starting a single foundation, or donating the boat you buy to one, and then using it to take kids out for sailing lessons and daysails, might raise more money.
Its still going to be a LOT of paperwork and overhead.
