Bluewater Sailboat Checklist: What You Need for Ocean Passages
Crossing an ocean in a sailboat is one of life's great adventures — but it requires a yacht that's up to the task. This checklist covers everything you need to consider before casting off for bluewater.
What Makes a Yacht "Bluewater Capable"?
Hull Construction
- Solid fiberglass below the waterline (no cored hulls in impact zones)
- Strong hull-deck joint (bolted through, not just bonded)
- Robust keel attachment with substantial backing plates
Keel & Rudder
- Deep fin keel or full keel for tracking and stability
- Ballast ratio above 30% for positive righting moment
- Spade rudder with emergency tiller capability (or full keel with protected rudder)
