A bluewater boat represents freedom and self-reliance at sea. But choosing the right bluewater boat requires a shift in priorities. Many sailors, often moving up from smaller coastal cruising boats, trust a “blue water” label without evidence. Don’t. A real blue water yacht is defined by one thing: its margin of safety. Ask yourself: can it handle a storm, a collision, or a major system failure?
This checklist distils lessons from years of ocean cruising sailing experience and community wisdom. It focuses on the structure and systems that make a boat genuinely bluewater voyaging and ocean-ready.
Bluewater Cruiser Structural Integrity
Your safety depends on the hull, keel, and rigging. These components keep you upright and afloat.
When were the keel bolts last inspected or replaced?
Fin keels rely on bolts that corrode over time. A failure during a grounding or knockdown can be catastrophic. If the boat is more than 15 years old and records are unclear, plan for a full inspection or replacement. Encapsulated keels, found on brands like Westsail or Island Packet, reduce this risk but need checks for hull blisters.
Is the rudder protected by a skeg or exposed like a spade?
A collision with debris can destroy an unprotected spade rudder and leave you without steering. Spade rudders improve handling, but a skeg-hung rudder offers far more protection offshore. Prioritise strength and reliability over agility.
Can the chainplates be inspected for corrosion?
Chainplates secure the mast, but often corrode out of sight. A failed chainplate can cause dismasting and hull damage. Ask for documentation on replacement, as standing rigging lasts 10–15 years on average. If the chainplates are hidden, it’s wise to budget for a professional inspection or replacement.
Is the hull solid fiberglass below the waterline?
Cored hulls save weight but can trap moisture and delaminate. For long-term durability and easier repair, choose solid fibreglass below the waterline. Avoid complex composites unless maintenance records are complete and verifiable.
Bluewater Cruiser Mechanical & Steering Systems
Does the bluewater sailboat have a reliable, non-electric backup steering system?
Autopilots fail—it’s a question of when, not if. Hand-steering for days is exhausting and unsafe. Install a wind vane self-steering gear or hydraulic bypass system. These mechanical backups require no electricity and can save your passage.
Can you reach essential maintenance points at sea?
If you can’t change a fuel filter or water pump while under way, you risk losing propulsion when you need it most. During your inspection, climb into the engine space. Check access to the dipstick, filters, belts, and stuffing box. If these points are hard to reach, the bluewater boat isn’t designed for offshore reliability.
Bluewater Cruiser Safety & Seaworthiness
Are all through-hull fittings bronze and accessible?
A failed seacock below the waterline can sink a boat fast. All fittings should be marine-grade bronze, not plastic, with double hose clamps. Keep a tapered wooden plug tied to every through-hull for emergencies.
Is the cockpit small, deep, and well-drained?
Large, open cockpits can fill with water during a knockdown. A safe blue water yacht cockpit is compact, deep, and self-draining, with high coamings and large scuppers. A hard dodger or fixed spray hood is a valuable safety feature, not a luxury.
Is there a secure berth near the centre line?
You can’t function offshore without sleep. Choose a low, centre line bunk with strong lee cloths to prevent injury in rough seas. Full-width aft cabins are comfortable in port but dangerous offshore.
Are the water and fuel capacities sufficient for extended bluewater voyage cruising?
Running out of fuel or water shouldn’t force you into port. Verify tank sizes and storage capacity for provisions, spares, and tools. A blue water sailboat must support months of self-sufficient living, not just a week at anchor.
