In this article, we’ll be taking a practical look at the maintenance of your catamaran, specifically inspections beneath the waterline when your boat is ashore.
When a boat is taken out of the water, take the opportunity to perform a series of checks on the propulsion systems and hull equipment located in the normally-submerged part of the boat.
Rudder, P-bracket and propeller:
- Rudder: check that there is no play in the rudder stock and check overall condition.
- P-bracket and stern tube: check the fixing, cleanliness and overall condition.
P-Bracket:
Stern gear: general
Stern tube: closer detail
Propeller anode: check it is tightly secured.
Anodes and ground plates:
Anodes and ground plates: if there is more than 50% wear, the anode must be changed. A Lagoon dealer will be able to supply you with the right product for your needs.

Through-hull fittings:
Check the condition of the boat’s skin fittings (through-hull fittings, ventilation fittings, etc.). These must not be blocked by algae, sand, mud or any other object that prevents air/water from getting out or in.
It is important to remove any algae or other external elements that may block the fitting.
Log impeller:
The condition of the log impeller blades should be checked: ensure there is no algae in the mechanism.
Optional: check the calibration of the sounder and the under-keel clearance offset.
Hull:
Undertake a hull condition assessment to check the state of the antifouling and thus know if it is still good or if it needs to be redone (with or without a new coat of primer).
It is essential to scrape or pressure wash any non-structural element of the boat below the waterline.
Tap the hull one square meter at a time looking for any breakage, holes, cracks or delamination.
If possible, get a hull survey done.
