Iguana Commuter.Iguana Yachts

• Iguana Yachts builds high-end "amphibious boats" that can travel on water and on land.
• The vessels aren't anything like the Amphicar of the 1960s — instead of wheels, they use stowable, tank-like tracks to rumble up onto beaches and down paved roads.
• Iguana Yachts sells several amphibious models built for different purposes, including the luxurious, $670,000 Commuter and the sporty X100.

What's a boater to do when all the spots at the local marina are taken? If you own a vessel from Iguana Yachts, the answer is clear.

The French company specializes in constructing boats that don't need to be docked at all. Instead, they're equipped with retractable, tank-like tracks that enable them to roll right up onto land. When it's time to go back out onto the water, you simply drive right into the waves and press a button to fold the tracks away.

The ingenious boats — one can imagine — would be great for those with waterfront properties. They also address the age-old, first-world problem of how to get from one's yacht to a hidden-beach picnic without getting wet.

Iguana Yachts sells a whole lineup of "amphibious boats," ranging from the adventure-oriented X100 to the luxuriously appointed Day Limo. Take a closer look at the unique vessels below.
