Top Tips from Rhys
Boatyard Manager Rhys Dempster shares his practical advice for keeping your boat in top condition over the quieter months:
“While ‘wintering your boat’ is more commonly associated with colder climates, the cooler season here in New Zealand still sees many vessels sitting inactive for long stretches. A bit of preventative care now goes a long way.”
✅ Keep Your Fuel Tanks Full
Top off your fuel tanks and add a fuel additive to prevent condensation forming — moisture in your tank can lead to diesel bug contamination, which is costly and time-consuming to fix.
✅ Check Your Seacocks
Ensure all seacocks are closed. While you're at it, open and close them a few times to test for stiffness or resistance. If anything feels off, note it for your next haul-out.
✅ Look After Your Electrics
Isolate any electrical systems not connected to your battery banks. All batteries should remain fully charged and ideally connected to shore power to cycle properly.
✅ Keep Airflow Moving
Mould thrives in sealed-up boats. Ventilation is key — open a weatherproof hatch if possible, or use dehumidifiers set to medium or a timer to protect interior timber.
✅ Schedule Maintenance Now
Winter is the best time to complete planned maintenance or upgrades. Avoid the spring rush and ensure you're ready for a worry-free summer on the water.
✅ Check EWOF & Lead Tag
Take advantage of downtime to ensure your Electrical Warrant of Fitness (EWOF) and Lead Tag are up-to-date and compliant.
✅ Clean the Bait Freezer
Not planning to use it? Empty and unplug your bait freezer. A power failure while it's full can lead to a far bigger mess (and bill) than just lost bait.
