Seakeeper Ride, fitted in Darwin
We're the only Seakeeper Ride Certified Dealer in the Northern Territory. We size it to your hull, fit it to the transom and link it to your display, so the boat runs flatter and drier in a chop.

Questions people ask
How is it different from trim tabs?
Its rotary controllers make the same kind of lift as tabs, but they act much faster and adjust on their own, wave by wave, which conventional trim tabs can't do.
Does it work when the boat is stopped?
No. Ride works under way. Seakeeper's gyro stabilisers are the product for roll at rest.
When does it start working?
Seakeeper Ride starts trimming the boat at about 10 mph, around 9 knots. Full stabilisation comes in at about 20 to 25 mph, around 17 to 22 knots.
Will it fit my boat?
Seakeeper makes it for fibreglass and aluminium monohulls up to about 55 feet, stepped or not, with a fairly flat transom. Send us photos of the transom and we'll tell you.
What does it need from my electrics?
A compatible display with an ethernet port, and a 12 volt supply that can deliver 10 amps for the 450, 525 and 600, or 14 to 16 amps for the bigger models.
What upkeep does it need?
Seakeeper says to check the zincs about every three months and replace them at about half worn, and to rinse the actuators with fresh water after each trip.
What's the warranty?
Two years from delivery when you buy through Seakeeper or an authorised dealer. It doesn't cover damage from sizing or installation, so the fit matters.
Big tides, short chop
Darwin Harbour's tide can range up to 7.8 metres, with currents up to 2 metres a second. Put that against the wind and the water stands up short and steep.
That's the water Ride is made for. It works under way and corrects on every wave, which trim tabs set once at the ramp can't do.
Salt is the price. Seakeeper says to check the zincs about every three months and rinse the actuators with fresh water after each trip, so we check them whenever the boat's in with us.
