New Break-Through Propeller Design
is
Faster, More Fuel-Efficient, Quieter
It isn’t often that we see a new product that’s so revolutionary that it breaks completely out of the box to provide a substantially improved user experience. This is the case with the Sharrow Propeller, a loop prop design that has applications in both recreational and commercial marine, aviation, and many other industrial applications. By solving the problem of blade-tip vortices which induces drag and thus slows a boat, leading to increased fuel consumption, the Sharrow prop has in one giant-step forward, improved most of the major metrics with which we measure boat performance.

Yamaha 275SD:
Twin Supercharged Jets,
2.4 Second Time-to-Plane
The Yamaha 275SD has a 27' (8.23 m) LOA and a 9' (2.74 m) beam, providing far more space than we’re used to seeing in jet-powered boats. Despite all that space and seating, her weight is modest at 5,466 lbs. (2,479 kg) without fuel. Since she’s powered with twin SVHO 1812 CC supercharged jet engines, performance is brisk, to say the least. She got on plane in 2.4 seconds in our tests, far quicker than prop-driven bow riders in class, and top speed was 50.2 mph. She also delivers on style, with sweeping side windows that add eye appeal and provide wind protection for those at the console seats. The hardtop with a sunroof is standard.

Zodiac Open 5.5:
Quick-Planing RIB w/2-Stroke Power
The Zodiac Open 5.5 is a RIB that is as capable as a multi-mission dayboat ready for water-skiing, fishing, diving or exploring, particularly when equipped with the new Evinrude E-TEC G2 115 H.O. The high-output Evinrude has prodigious torque at the low end, which RIBs need to easily get on plane. She planed in just 3.5 seconds and had a top speed of 46.5 mph. The lightweight 3-cylinder engine also proved to be extremely fuel-efficient. At 1000 rpm and 4.9 mph, it got 12.3 mpg thanks to the electronic direct fuel injection with “stratified combustion” at low speeds -- about twice what competitive 4-strokes can manage.

Fusion Apollo RA770 Stereo:
Designed & Engineered Specifically
for Marine Applications
Fusion Apollo RA770 Marine Entertainment System
The Fusion Apollo RA770 Marine Entertainment System was designed specifically for recreational boats, and as such fits the specific and unique needs of boaters. It is not a warmed-over car stereo system, but that is just the beginning of Fusion’s remarkable story. It is the first we’ve seen with a color touch screen display, making control intuitive. And, it operates with its own Wi-Fi connectivity, which means the playlist from your smartphone or tablet can go with you on the water and you’ll hear it in full fidelity, unlike with Bluetooth systems. We explain why The “Fusion-Link” app sets up and tunes the system in minutes. Sound can be tuned to each speaker -- add more bass in the cockpit and less in the cabin, for example. The app also allows your phone to act as an added remote stereo control. But this is just the beginning of many features. See Captain Steve’s tour here...

World Cat 320DC:
Multiple Advantages in a Multi-Hull Cat
The World Cat 320DC is a power catamaran with all the advantages inherent in the dual hull design. She delivers a smoother ride in choppy water than a monohull of similar dimensions. She is more stable at rest, has more usable space in the interior due to the squared off bow and nearly vertical hull sides, and she offers the security of completely redundant power systems including twin outboards, separate fuel systems and separate batteries -- which is a big plus offshore. Cats also float very shallow for their weight. This one needs just 16" (4.64 cm), which is great for slipping in to a beach for a swim or a picnic. See the full walkthrough here ...
