Stobbo I get you on this I am a C-Tug fan and of course they are Kiwi made
I have one for my Revo 15/16 worx great.
But my AI is too heavy for the small wheels at 64Kg plus gear and it plows, even with the extensions, on soft sand.
Everyone's requirement is a bit different, from my Cara Park cabin to the beach is 150 yards of first sealed tarmac, then grass then soft sand.
The Hobie TI beach dolly is good but over-spec for my AI since its really made for the TI and it wont stow in the hatch meaning another walk back to the cabin, plus its $500+.
I finally settled on this very good $295 Cart that is recommended by all the AI guys on the Kayak fishing forum.

Don't worry about the soft-looking tyres getting punctured by stones, these are much tougher than they look and can be repaired seamlessly.
