Maintaining your yacht’s hull and deck is essential for safe, trouble-free boating. This yacht hull and deck inspection checklist guides you through routine preventive inspections, helping you catch minor issues before they become costly repairs. Whether you’re a beginner or have some experience, following this checklist regularly will protect your investment and improve safety.

Inspection Frequency Overview

• Pre-Departure (Each Trip): Quick visual scan for obvious damage or loose gear.
• Weekly: Light deck and hardware check.
• Monthly: Thorough topside inspection including fittings and joints.
• Pre-Season / Haul-Out: In-depth examination of hull, deck core, fittings, and structural joints.

Pre-Departure Quick Scan

Before every outing, walk around your yacht’s exterior to spot:

• Fresh hull cracks, gouges, or chips in the gelcoat.
• Loose deck hardware such as cleats, stanchions, and winches.
• Clear decks and cockpit wells of debris blocking scuppers or drains.
• Obvious leaks or stains on deck surfaces or below hardware.

A quick tug test of cleats, handrails, and lifelines confirms tightness. Blocked drains or loose fasteners on deck can cause unexpected issues underway.

Weekly Deck and Hardware Check

Spend 10–15 minutes weekly for:

• Inspecting deck surfaces for soft spots or signs of core moisture (use a lightweight tap test with a screwdriver handle).
• Cleaning hatch seals and locker gasket mating surfaces to avoid leaks.
• Checking all deck fittings for signs of corrosion, cracks, or spiderweb fractures radiating from fasteners.
• Ensuring drains and scuppers remain clear of debris.

Monthly Detailed Inspection

On a monthly basis, dedicate time to:

• Walk the hull sides and deck, using a flashlight angled low to highlight gelcoat cracks or blisters.
• Check the hull-to-deck joint carefully for gaps, movement, or staining; this joint is critical for structural integrity.
• Inspect through-hull fittings and seacocks for corrosion, smooth valve operation, and secure double hose clamps below the waterline.
• Evaluate the condition of all deck hardware backing plates to ensure proper load distribution and sealing.
• Document any stains or soft areas with photos and notes for trend tracking.

Pre-Season and Haul-Out Checks

At haul-out, or before extended heavy use, a full inspection includes:

• Close examination of the hull below the waterline for osmosis blisters or gelcoat damage.
• Assessing keel bolts and the keel-hull junction for weeping or corrosion.
• Testing rudder bearings for play or moisture intrusion.
• Detailed deck core inspection using tap tests and moisture meters.
• Verification of hatch and portlight seals, including replacement of worn gaskets.
• Reviewing all exposed hardware and fasteners, resealing and re-bedding as needed.

Professional help is often needed to address structural issues or core rot found here.

Warning Signs Indicating Professional Help Needed

• Soft or spongy deck spots detected by touch or tap test.
• Noticeable gaps or movement in the hull-to-deck joint.
• Persistent leaks around hardware, hatches, or portlights.
• Blisters larger than a thumb or spreading in hull gelcoat.
• Excessive rudder play or stiff steering mechanisms.

Ignoring these can lead to serious damage and costly repairs, so prompt professional evaluation is recommended.
