Just a reminder that new lifejacket rules comes into effect today. On a boat 6m or under, your lifejacket needs to be worn whenever you’re underway.

It's a good time to check the fit of your current lifejackets (especially for the kids!) and if it’s an inflatable, check the cylinder. Come and see the GT Marine team to upgrade yours.

When things go pear-shaped on the water, it pays to have more than one person on board who can take the helm.

Coastguard Kaipara are running an awesome free workshop on exactly that - essential boat handling and safety for when you're suddenly in charge of the boat. Ideal for the crew who are always on board but rarely the skipper.

Registration details are in Coastguard Kaipara's post below. 👇

SUDDENLY IN CHARGE - Kaipara A skills and confidence-boosting workshop for crew. What would you do if you were suddenly in charge on the water?

Dialled in. Sea trialled. Ready to send it.

A few of our latest Honda fit-ups, all set for the season. Getting the right outboard is only part of the job, the install matters too. We know Honda outboards inside and out, and every fit-up is sea trialled to make sure we’ve got the right prop for your boat, balancing performance, RPM and fuel economy.

Right now you can save up to $3,500 on selected new Honda outboards.

Get in touch for a quote and let’s get your boat ready for the season.

You know that moment when the fish are on and you're still wrestling the anchor up by hand? Bad timing, sore back, wasted minutes.

We just fitted a winch to this Extreme 570 and it sorts all that out. Drop it, retrieve it, move on. No more hauling chain when the workups shift.

Chase the bite instead of chasing your breath, which means more fish in the bin.

If you're keen, flick us an email or pop in and we'll talk you through what suits your boat.
