7.5m Amphibious Aluminium Fishing Boat NZ | Flyfin 750HTA
Built for anglers who’ve outgrown the 700HTA and want the range to fish further from home, the Flyfin 750HTA is a 7.5m amphibious boat designed and built by Flyfin Boats in Papamoa Beach, New Zealand. The Tectrax T3000 Gen2 wheel system drives the boat down a suitable beach and straight into the water, so you can launch where a boat ramp doesn’t exist. Rated for 225 to 350 hp, with a 250L fuel tank and upholstered panels in the hardtop roof, it’s an amphibious fishing boat with the headroom for longer days and bigger crews.

Frequently Asked Questions
The Flyfin 750HTA is a 7.5m amphibious boat designed and built by Flyfin Boats in Papamoa Beach, New Zealand. It's the step up from the 700HTA, with a 250L fuel tank, a rating of 225 to 350 hp and the Tectrax T3000 Gen2 wheel system built in, so you can drive down the beach and launch without a ramp.
The Tectrax T3000 Gen2 system deploys electrically driven wheels that let the boat drive itself down a suitable beach or shoreline and into the water, with no trailer or boat ramp needed. Once you're afloat, the wheels retract.
Range depends on terrain and battery configuration. The standard lithium iron phosphate (LiFePO4) battery supports typical launch and retrieval, and range-extending battery packs are available as an option.
No. The Tectrax system is designed for launching and retrieving at the water's edge, not for road use. The boat travels on its Flyfin Aluminium Trailer, and the wheels take over at the beach.
The Tectrax T3000 Gen2 is rated for inclines of up to 15°, which covers most natural shorelines and boat ramps.
The standard 750HTA package includes a Mercury 225 hp outboard, and the hull is rated for 225 to 350 hp.
The 750HTA is 540mm longer than the 700HTA, with a wider 2.55m beam, a 250L fuel tank instead of 200L, a higher 225 to 350 hp rating, a 600kg payload and upholstered panels in the hardtop roof. The 700HTA remains the most compact amphibious model and the easiest to tow and handle.
The Tectrax system is designed for minimal maintenance. Rinse it with fresh water after saltwater use and follow the Tectrax service schedule. The system is covered by a 3-year warranty, and the battery by a 10-year warranty.
