Why dry dock
Salt water never sleeps.
Every hour your hull sits immersed, salt water is working on it — corroding metal, growing slime, dulling performance. Here's what's really happening below the waterline, and what it costs you.
The three attacks
What immersion does to a moored boat
Electrolysis
Dissimilar metals in salt water form a slow battery. Props, shafts, stern drives and fittings corrode — quietly, constantly, expensively.
Marine growth
Slime forms within days, then weed, then barnacles. Growth adds drag, chews fuel, and grinds performance down season after season.
The anti-foul treadmill
The standard defence is toxic coating, re-applied roughly every 12 months — with slipping fees, yard time and a slower hull as part of the deal.
The dry dock answer
Take the hull out of the fight
Anti-foul tries to make immersion survivable. A floating dry dock removes the immersion.
The moment you dock on an Aqua Boat Lift, your hull rises clear of the water. No immersion means no electrolysis pathway, nothing for growth to colonise, and no coating to renew. The hull stays clean and fast — and boats with a documented dry-docked life hold their value noticeably better at resale.
Unlike hardstand or trailer storage, the boat never leaves the water's edge. You keep the convenience of a berth with the protection of the yard.
Your options, honestly
Comparing ways to protect a berthed boat
| Approach | Hull protection | Time to launch | Ongoing cost & effort |
|---|---|---|---|
| Moored + anti-foul | Partial — coating slows growth, immersion continues | Immediate | Re-coat ~yearly, slipping fees, diver cleans, more fuel |
| Trailer / hardstand | Full — hull dry | Slow — tow, queue, ramp, retrieve | Storage fees or yard space, launch effort every trip |
| Floating dry dock (Aqua Boat Lift) | Full — hull dry at the berth | Minutes | Minimal — no coatings, no slipping, low upkeep |
Comparison is general in nature — your berth, boat and marina rules all factor in, and we'll talk them through when we quote.
Proof under pressure
Good enough for a rescue callout
Emergency services don't buy convenience — they buy readiness. NSW Fisheries and Port Lincoln SES keep response vessels on Aqua Boat Lifts because a dry, clean hull launches in minutes and needs almost no attention between callouts.
If it earns its keep on a rescue pontoon, it will earn its keep in your berth.
