According to them, you would be able to control the Nereus by just turning the handlebars, like using any bike. The handlebars are attached with strings to the kite, employing the same principles used in kite-surfing. To dive, you only have to push down, and the Nereus will dive for a few seconds before emerging again because of the kite dragging it out of the water. Sounds crazy, and we want one. [Behance]

The boat is made from 100 percent carbon fiber and has an LCD touch-screen control system, leather trimmings and, most importantly, photovoltaic cells on almost all its horizontal services. Czeers is hoping to produce between 4 and 8 boats per year. Pricing is not yet available, but considering that the last version of the MK1 was last shown at the Millionaire Fair, you can probably bet it's super expensive. [Gizmag]

Simply remove the two pins and pull the central lever. Users can also adapt the board according to their needs, all thanks to the set of hot-swappable fins. It is a shame then that this is just a concept, but due to the likelihood of losing of itty-bitty board parts, perhaps that's for the best. Hit the link for two swanky close-up shots. [Yanko Design]

It doesn't look half bad, either, with its fiberglass shell over a foam core, and it's available in a variety of colors. At $3170 it's about half the price of its competitor, the PowerSki which works in a similar way but has a much more powerful 55hp two-stroke engine. So is this Powersurf FX fast enough?

This Powersurf FX's makers don't say how fast it will go—only that it will "give you the power and performance you need," but they do point out that you can still use it like an ordinary surfboard, taking it where other personal watercraft (PWC) or power boats can't go.

Judging from the photos in the gallery, it looks like it's going just fast enough to be dangerous. It just might be good for a thrill or two. Looks like this sucker arrives just in time for those of us who grow weary of trying to surf in Lake Michigan every summer. – Charlie White

Casio has brought out a waterproof casing for its Exilims EX-Z65 and EX-Z75. However, it will only go down to 10 feet, so it's more suited for the snorkelers among you rather than scuba divers. The cute flame-colored housing does, however, protect against sand, which could be useful if you're always dropping things (I am) and planning on spending summer down at the beach (I'm not). – Ad Dugdale

Casio's snazzy gear for underwater cameras [New Launches]

This floating cabana is made of heavy-duty PVC and seats up to six people. With a nylon canopy to protect you from the sun and a tethered 16-quart cooler to keep your tinnies and snacks at the right temperature, it goes perfectly with the remote-controlled poolside drink tray you saw earlier this week. Measurements are 82"x102"x76" (HxWxL) and you and your crew can climb on board as long as you don't tip the scales at over 1,020 pounds.

The $300 inflatable has a hole in the middle (may I reiterate that it is NOT THAT KIND OF BLOW-UP THINGY) for easy access to the water, but the porthole looks so tiny that only the Nicole Richies of the world can fit through. May we suggest one design modification: Make the cabaña remote-controlled, so that your butler can bring you home should you drift too far away from the yacht. – Ad Dugdale

If you yourself are water-resistant, the headphones' durable neckband holds them tightly in place for some rip-roaring skiing action, too. Available this week for $39.
