Look for a sailboat 30+ feet or a trawler with a spacious cabin. Prioritize a sound hull, working engine, and good bones over cosmetics. Get a marine survey before purchasing.

Upgrade the galley with a propane stove with oven, a 12V refrigerator, deeper sinks, and better counter space. Add fiddle rails and secure storage for rough conditions.
