Go small, go simple, go now. The pardey's.There was some cruiser motto, I forgot most of it but the important bit is just "go now"
It is the only way to go sailing cheap, IMO. It's way cheaper than scavanging abandonned boat. Done it to. But I now live on my 27 footer and with a bit of DIY and not much money, am able to maintain her ship shape.
Go now, learn and earn as you go. You can go very, very far just coastal cruising to get to now the things of life at sea, wich sound very attractive but many a young traveler has given up with this lifestyle when tried out in real life (being boat owner is very, very different of just hitching a ride here and there. Thousand time more instructive, thousand time more a pain in the ass).
