What common problems should I check for when buying a used Bavaria 37 Cruiser?

Check the keel support structure, rudder bearings and saildrive service history first: damage or neglected maintenance can make a cheap Bavaria 37 Cruiser expensive to own. Then check deck leaks, standing rigging and onboard systems, and make the purchase subject to an independent survey, haul-out and sea trial.

Identify the boat and inspect keel

Bavaria used similar names for different generations: an early Bavaria 37, a mid-2000s Bavaria 37 Cruiser and a later Cruiser 37 are different boats. Confirm the hull identification number, build year, engine model and saildrive model before ordering parts or accepting advice specific to a model.

Ask about groundings, charter use and structural repairs. Charter history alone need not rule out a boat, but undocumented grounding repairs warrant close investigation.

• Lift the saloon floorboards and inspect the bilge around the keel bolts, transverse floors and bonded internal moulding.
• Look for cracked laminate, separation along bonding edges, distorted joinery, rusty streaks and fresh paint covering isolated patches.
• During haul-out, inspect the keel-to-hull joint, keel leading edge and hull immediately ahead of and behind the keel.

A fine crack in the joint fairing needs assessment; an opening joint, displaced structure or internal cracking calls for a surveyor experienced in grounding damage. Light rust on a cast-iron keel is usually a maintenance job. Substantial corrosion or movement needs further investigation. Do not let anyone simply tighten the keel bolts to hide symptoms: torque and repair procedures must match the installation.

Inspect the engine and saildrive

Many examples have Volvo Penta diesels, but engine and drive combinations vary by year and replacement history. Read the identification plates and ask for invoices, particularly for the saildrive hull diaphragm, cooling system and exhaust elbow.

Volvo Penta commonly specifies replacement of the rubber saildrive diaphragm every seven years; confirm the requirement for the fitted drive. A clean-looking seal proves nothing about its age. Without documentary evidence, budget for replacement, often about £1,500 to £3,000 including labour and lifting, depending on access and local rates.

1. Start the engine from cold. Watch for prolonged cranking, persistent smoke, coolant leaks and poor seawater discharge.
2. Check engine oil and coolant, then inspect mounts, hoses, the seawater pump and exhaust mixing elbow.
3. Check saildrive oil for milkiness and ask whether any previous water contamination was traced and repaired.
4. Under load, check gear engagement, vibration, operating temperature and whether the engine reaches its specified full-throttle speed.

Inspect the aluminium drive casing for corrosion, unsuitable antifouling and neglected anodes. Check that the anode material and electrical isolation are correct; adding anodes indiscriminately will not identify the cause of corrosion.
