>>1170047>The problem is the high cost for food and marinas.
Nah, food is cheapish (rice, dry beans, etc). Marinas are comfy if you're rich, but there are lots of free harbors. What really will cost you are repairs that you can't do yourself and gas.
Also I would highly advise you do some time crewing on others people's ships before jumping in with both feet. Sailing is an awesome and rewarding hobby but the ocean is serious shit. It's not like a road trip, you can't just pull over and call for a tow when things get rough.
