Sealegs IKA-11, the world’s largest amphibious boat, up for sale

NZ-based Sealegs has a garage sale, auctioning off the largest land-crawling boat it has ever built

It’s billed as the world’s amphibious boat that’s able to head out to the continental shelf, and once you’re back, drive to the corner shop for a pie. And it could be yours for less than $1 million.

New Zealand-based wheeled boat specialist Sealegs is selling off the IKA-11, its largest-ever build to date.

It’s taken the unusual step of disposing of the five-year-old prototype combat craft by auction, with bidding kicking off yesterday with a list price of a little less than $250,000. However, if you want to bypass the entire auction process, Sealegs will be happy to seal the deal with a cheque nudging $1 million.

That’s a bargain considering Sealegs has spent more than $3 million to develop the IKA-11 to military-grade specifications.

The 11-metre, 6.3-tonne boat was built in 2017 as a showcase for the US military, but is now back home in NZ and taking up space in the shed.

All three wheels are driven, and the boat can climb up to a 30-degree incline meaning it can scale small hills to gain a higher vantage point, getting there across land at a speed of up to 16km/h.

MerCruiser power

Powering the IKA-11 are twin 370hp MerCruiser diesel engines with 100 hours on them, feeding their performance via a ZF-sourced gearbox to another NZ innovation, a pair of Hamilton HJ241 water jets.

Using water jets instead of sterndrive legs means the IKA-11 comes with a shallow 0.6-metre draft.

Should you win, for your money you also get a fully enclosed wheelhouse with forward-leaning front windows, giving it a tough, aggressive look, a folding Targa arch that greatly reduces the height of the boat once the wheelhouse is removed, and a hydraulically activated boarding ladder.

While this boat was built to military spec, Sealegs also proposed that it could easily be customised to cater to the “discerning luxury end of the recreational market”.

The auction closes on November 1.
