A review from California

Santa Barbra

6 metre fibreglass half-cab. 2019

WHAT A SUCCESS!!! The boat is a whole new boat, for the better. This [photo] shows boat fully loaded with full fuel and full water, plus a bunch of likely unneeded ballast in the hull (what I used before, to keep center of gravity low, which I can probably remove now). Thanks so much!

A review from Hawaii

Aiea, O'ahu Island

Salvador. 16ft fibreglass (cuddy cab). 2016.

I finally got a chance to take the boat out with the newly installed boat collars and all I can say is WOW!!!!!!!!!!! The excessive leaning issue I was having with the boat is completely gone. It feels like a totally different boat.

It handled very well and felt very stable in about 2-4 foot sea swells. The collars truly enhanced my boats handling and performance.

I now have great confidence and peace of mind when I travel further out to sea. My wife and I would like to thank you for an awesome product and wish the company well.

Vince. 16ft Duroboat (alloy, side console). 2017.

I put the boat collar on and think it has save me a few times because we go out in some pretty rough seas some times.

It has really helped to stabilize the boat when we walk around getting stuff ready for diving, surfing or kiting.

Review from New Zealand

Te Hapara, Gisborne (Nth Island)

Andrew. 16ft Fryan (alloy, fwd steer). 2016.

I got the Collar on the boat and have had it in the water a few times since. Really happy with the performance - plans a little earlier and soooo much more stable.

I had the whole family on the boat (6 of us) at the lake, and no problems at all.

Everyone comfortable, and no tippi-ness; awesome!

I've put in a couple of photos of us at the lake. This was prior to me trimming off the excess at the end before fitting the Transom Foam - which has worked well.




Review from United States

Redding, California

Richard. 19ft Jet Craft (plate alloy, centre console) - commercial dive boat. 2016.

Due to Richard's boat being an inboard jet-craft, we advised him to encase the Collar in aluminium and weld it to his boat.

Transom Foam on Jet Boat

I moved the boat to Sea of Cortez, in Mexico. While diving, the fuel line became blocked and we were adrift for 2.5 hours in 3-4 foot swells with wind 10 knots. The boat did well. Felt stable the entire time. Some got sea-sick but none felt unsafe.

The Collar additions and the mods bode well.
