MarineKart – a go-kart for the water


On the shores of lake Worthersee in Austria  (the same place the annual Wothersee festival for VW/Audi fans takes place) is a small company called Marinekart. They build compact little boats which are versatile, adaptable, supposedly unsinkable, and lots of fun.

The MarineKart is basically a go-kart for the water. It can carry up to four people, weighs just 127 lbs (58 kgs) without a motor, and is powered by an electric outboard motor, of which there are two to choose from, a 2.7 hp unit and a 5.4 hp model. It can also be powered by conventional four-stroke outboard motors.

While the power output of the electric motors might not sound like much – mainly because it isn’t very much – the featherweight construction and the compact size of the boat means it’s quicker than you might think. The base model – powered by a Torqeedo 2R 24V motor has a top speed of 9 knots, while the more powerful Torqeedo 4R 48V model has a top speed of 15 knots. Apparently the boat can handle up to a 10 horsepower motor, allowing for a top speed of around 30 mph.

Strand Craft V8 Wet Rod luxury PWC

Strand Craft V8 Wet Rod luxury PWC

Thinking about it now, it seems odd it’s taken this long for someone to come up with the idea of a luxury, high-class jetski or personal water craft. Generally speaking, if you’re in the market for a PWC, you have the choice between the more difficult to ride but sportier single-person standy-uppy style, or the more common design with anywhere between one to three seats. Generally speaking they’re covered with garish graphics and look like sportsbikes of the water. Nobody, until now, has offered a classy-looking jetski.

The Strand Craft V8 Wet Rod is a 16-feet (4.8 metre) long vessel capable of carrying up to three people. As the name suggests it’s powered by a 5.7 litre V8 engine producing 300 horsepower which is connected to a water jet drive. Top speed of the vehicle is a claimed 65 mph.

Wider 42 – Morphing yacht lives up to its name

WIDER 42 yacht

Wider are an Italian company who are in the business of building luxury yachts. They offer several models, up to and including 165-foot superyachts. However their 42-foot model is one of their more intriguing models.

The Wider 42′ was developed from a concept by Tilli Antonelli, and the styling was honed by Fulvio De Simoni. It incorporates a transformable mid-section which can significantly widen the vessel at the touch of a button. In just 12 seconds the width of the main deck nearly doubles, while at the same time outrigger pontoons extend into the water to provide additional stability.

At the rear of the Wider 42, a multi-configuration sun deck can provide space for a small tender or a jetski. Alternatively it can be used to stow diving equipment or as a place to mount a fishing chair for catching big game fish.

SWATH Electra Glide luxury yacht tender by SCOD

SWATH Electra Glide Limousine yacht Tender by SCOD

Making its debut at the Electric and Hybrid Marine World Expo 2014 in Amsterdam later this month will be the SWATH Electra Glide Limousine, a luxury yacht tender with a SWATH wave-piercing anti-roll twin hull. The vessel also features, as you have probably already guessed, an electric drive system which offers up to 40 nautical miles of range.

The vessel has been designed by SCOD (Sauter Carbon Offset Design) and is being built by the NEDSHIP group at their Turkish shipyard. The hull is formed from carbon epoxy, and the interior offers plenty of space for up to 14 passengers. Despite being primarily designed as a tender for large megayachts, the vessel can also act as a recreational day boat, offering a galley kitchen, bar, flat screen TVs, air conditioning and a rear dive platform.

Hot Tub Boat – sitting in a boat full of water is now good

Hot Tub Boat

Hot Tub Boats, based in Seattle, Washington are in the business of building boats that are purposely designed to keep their occupants soaking wet. For any other boat company this would be a disastrous proposition, but when you’re offering a boat / hot tub combo it somehow works.

The vessel is not just a simple dingy filled with some warm water though. It’s a custom-built design with luxury appointments and plenty of hidden gadgets. The 15-foot (2.4 metre) Hot Tub Boat features a built-in diesel boiler with thermostat control which can get the water up to a very toasty 104F (40C). Propelling the craft is a quiet 24-volt motor offering a top speed of 4 knots. The boat is controlled via a small joystick located on the deck on the right hand side. The batteries provide up to 10 hours of cruising time before requiring a recharge.

Rolls-Royce Merlin V12 powered Aeroboat

Claydon Reeves Aeroboat

The British yacht design studio, Claydon Reeves, has just put the finishing touches to their latest design. Called the Aeroboat, the styling of the luxurious powerboat was inspired by the Royal Air Force’s most famous aircraft of all time, the Supermarine Spitfire.

Powering the Claydon Reeves Aeroboat is a Rolls-Royce Merlin V12 engine, one of the most iconic, and storied engines of all time. It was developed in the 1930s, and saw action in the Second World War as the powerplant of some of the best-known war birds of the era – including the Supermarine Spitfire and the Hawker Hurricane. It’s a huge hunk of engine, 27 litres in capacity and in supercharged form capable of producing over 2,000 horsepower.

Nauti-Craft 2Play catamaran offers full suspension system

Nauti-Craft 2Play catamaran suspension system

The Nauti-Craft 2Play catamaran is one of the few boats to feature a full suspension system. And that’s kinda strange when you think about it. Because the open sea is usually far rougher than any road surface – with the possible exception of roads in Michigan. It’s not uncommon for powerboats to have seats with built-in air suspension, and certainly offshore racing boats have them. But to have the entire deck riding atop a suspension system is unusual. One of the only other watercraft to employ a similar system is the unusual and highly advanced SeaPhantom built by Maritime Flight Dynamics Inc.

However unlike the SeaPhantom, the Nauti-craft 2Play catamaran is a much more versatile vessel with a more practical and familiar deck layout. If it wasn’t for the advanced suspension system it would be fairly unremarkable.

The 26 ft (8 m) Nauti-Craft 2Play catamaran is just the latest in a series of prototypes the Australian company  have developed to test the system in real-world conditions. Prior to building prototype boats, the company used computer simulations to evaluate the design.

Amphicruiser AWD Amphibious Off-Roader

Amphicruiser AWD amphibious car

The Amphicruiser is an all-wheel-drive amphibious vehicle built by Dutch Amfibious Transport (DAT). The Amphicruiser is based on a custom-built chassis and powered by a 4.2 litre engine from a Toyota Land Cruiser. Many of the Amphicruiser’s components have also been lifted from the Land Cruiser to ease the construction process and reduce costs.

The Amphicruiser has a very rugged, practical look about it. DAT say that they haven’t sacrificed any of the vehicle’s off-road ability by making it amphibious. It’s equally at home on the road, off the road, or in the water.

The Amphicruiser is powered by the Toyota engine on both land and in the water. When out of the wet stuff, the engine drives all four wheels. When in the water, at the push of a button, the power is diverted from the wheels and to a jet drive system. In the water the Amphicruiser has a respectable top speed of 8 mph. Not quick. But pretty good for something which can drive itself into and out of the water.

USS Zumwalt, Guided-Missile Destroyer of the Future

USS Zumwalt guided-missile destroyer

On April 12, 2014, the US Navy christened the first in a new class of guided-missile destroyers. The USS Zumwalt is the first in the Zumwalt class of vessels. They are next generational in almost every single way, from its weaponry to its drive system, the USS Zumwalt is almost straight out of a science fiction book.

Named after the late Admiral Elmo R. “Bud” Zumwalt Jr., who served as the 19th Chief of Naval Operations (CNO) from 1970-1974. Zumwalt was a veteran of World War II, as well as the Korean and Vietnam Wars. He is credited with implementing a series of policies intended to improve opportunities within the Navy for minorities and women during his tenure as CNO. Zumwalt died Jan. 2, 2000. During his eulogy, President Bill Clinton described Zumwalt as the “conscience” of the Navy.

The Zumwalt-class of destroyers, like the man, is designed to be forward-thinking and versatile. The USS Zumwalt is the first of three destroyers the U.S. Navy has ordered.

Saunalutta – DIY Sauna Raft from Finland

Saunalautta sauna raft

The Scandinavians love their saunas. It’s part of their culture. But unless you happen to have oodles of money and a large luxury yacht, its hard to combine saunas and boating. Unless you go the budget route like these enterprising Fins did and knock up your own floating sauna raft, or Saunalutta as it’s known in Finnish.

Created by a group of friends in Joensuu, Finland, the Saunalutta sauna raft basically consists of a shed sandwiched between two decks. The shed contains a small changing area/storage room and a decent sized sauna. The lower deck of the sauna raft features a rear swim platform and also provides a mounting point for the small outboard motor used for propulsion.
