Quick answer
Start with a systematic visual inspection, then check by touch and movement, and finish by testing mechanical function (lifting/dropping the centreboard/daggerboard and trying fittings). Look for cracks, delamination, missing or loose fastenings, dents and sand or grit trapped in seals and bearings.
Useful checklist (do these on the beach or ashore)
- Hull surface
- Walk the hull visually from bow to stern in good light. Look for fresh scratches, gouges, cracks or areas where gelcoat or paint is missing. Run your hand over suspect areas to feel soft spots or raised blistering (delamination).
- Check around the waterline and keel area for impact marks and compressions.
- Centreboard / daggerboard
- Inspect the board for straightness, edge nicks, chips or cracks. For wooden boards check for signs of swelling or separation; for composite boards check for delamination at the edges.
- Operate the board through its full travel. Listen for unusual noises, feel for binding or excessive play in the trunk and pivot/guide points.
- Fittings and fastenings
- Check bolts, rivets and screws that secure cleats, shrouds, travellers, rudder fittings and the centreboard trunk. Look for corrosion, looseness or missing hardware.
- Inspect seals, bushings and bearings for sand, grit or corrosion. Clean and lubricate where appropriate.
- Beaching-specific checks
- Look for abrasion or worn patches where the hull contacted the sand or rocks; feel for thin or soft areas.
- Check the rudder and skeg for chips or bending; ensure the pintles and gudgeons are intact and not elongated.
Why this matters
Impact damage, trapped sand and loose fittings can quickly escalate into leaks, gear failure or loss of control if not addressed. Early detection lets you make temporary repairs and plan proper fixes before further sailing.
Common mistakes
- Only doing a quick visual scan and missing soft spots that you can feel by touch.
- Forgetting to operate moving parts — a centreboard may look fine but bind under load.
- Not cleaning sand and grit from seals and bearings, which causes accelerated wear and jamming.
Practical next step
If you find anything significant (cracks, delamination, bent fittings, excessive play) stop sailing and either perform an appropriate temporary repair or take the boat to a marine repairer. For uncertain cases, photograph the damage, note where and how the boat beached/impacted, and consult a qualified rigger or boatbuilder.
Terminology note: "Centreboard" and "daggerboard" are lifting foils that reduce leeway — a centreboard pivots or lifts into a trunk on an angle, a daggerboard slides vertically; "fittings" are metal or plastic hardware like cleats, bolts, pintles/gudgeons and travellers.
