2021 Hammer Yachts 35 "HAMMERCAT 35-108"

Horsepower vs Weight ratio: Hammer Yachts builds power-catamarans which are 40% lighter compared to other vessels, which means that a HammerCat needs half the horsepower to get the same performance. Speed is mostly about horsepower vs weight ratio, the same with sports cars, bikes, planes, you name it. There is no reason for a quad engine set up on a HammerCat. We still get the same performance, yet we run very fuel-efficient with an amazing range.

All HammerCats are 100% epoxy composite construction with a standard carbon fiber hardtop. We use top of the line materials and the latest technology to ensure a strong and stiff hull.

It's all about the ride: The HammerCat 35 offers an exceptionally comfortable and dry ride even in the most challenging conditions. Our design brief for the HammerCat 35 was to design a power catamaran that would challenge the status quo in the center console power cat market and build “the next generation of power-cats”.

The meticulously designed underwater body of the HammerCat 35 was drawn up by a true power-cat designer who spent countless hours running CFD simulations and fine-tuning the many factors that make up the hull of a center console power-cat. The HammerCat 35 features a wave piercing bow / very sharp entry, double stepped hull that draws air in from the sides so that the HammerCat rides on a cushion of aerated water while at cruising speed and boasts a Carolina bow with beautiful and very functional flare.

We have all seen boating videos of center consoles going through rough water / inlets, where boaters hold on for their dear lives. You won’t see these videos featuring a HammerCat.

The HammerCat 35 hull is optimized for the working window around 35-40 mph for efficiency and comfort in all sea states. There is no other hull producing a softer exit through a wave.

The lighter weight ensures that the HammerCat gets on a plane earlier and runs more efficiently. If you look at the bridge deck (the height from the water surface to the underside of the tunnel in between the hulls) you see that there is a significant difference between the ‘previous generation’ power catamarans and the next generation power-cats: the HammerCats.

What does more clearance do? More bridge deck clearance facilitates the passage of the water which travels underneath the boat from the bow to the stern. Less ‘wet area’ means less friction, which reduces fuel consumption and eases the bumping and slamming you might notice on power catamarans with less (or none) bridge deck clearance.

Look at bridge-deck heights of other power-cats next time you’re at a boat-ramp or boat-show. Then compare the stern height / bridge deck clearance and bow height of a HammerCat with any other power-cat in this size range. You will notice the stark differences in bridge deck clearances which really show off their functionality on the water.

We aim to keep the crew and guests dry. A low center of gravity and 12’ beam with multiple deflecting streaks and chines redirect wave energy and wake energy outward and downward to dampen the movement in a seaway. The wave piercing hulls slice through waves instead of slamming or pounding, let alone having each small wave create slamming under your feet. This results in a softer, dryer ride and eliminates the fatigue experienced when driving other power catamarans.

Twin engines vs Quad engines: We often get asked why we don’t use a “quad engine” set up. The short answer is that we have the same horsepower to weight ratio as most other center console power catamarans because we build a lighter vessel. Building with epoxy and carbon fiber results in a 40% weight reduction, so there is no need for quad engines while maintaining the same HP-weight ratio.

Quad engines would adversely affect the boat dynamics: more engines, more weight (at the very end of the boat), needing more fuel. More engines actually result in a negative vicious circle.

The advantage of our twin engine set-up on a lighter boat is easy: less fuel consumption, more range, less maintenance, less insurance (check the difference in annual insurance cost between a twin vs quad engine boat) and a better entry price level! And if you still wonder about quad vs twin engines: offshore racing catamarans only feature twin engines as they chase the mix of best performance vs solid construction vs light weight. We simply replaced “performance” with “comfort in ride” at cruising speed for our HammerCats.
