HammerCat 45

Fast, Luxurious, Light, and Fuel Efficient.


The Design Details

2021: the year of the introduction of the HammerCat 45

The HammerCat 45 is multi-functional power catamaran: sport fishing, diving, lounging or all of the above in one superior yacht. The sleek hull design is a good indicator of her performance. The elegant lines are an example of HammerCat heritage. The concept of the HammerCat 45 is to offer a complete package of on-water entertainment while not compromising on performance or looks.

The (optional) opening bow allows your guests to disembark on the beach or in very shallow water without getting wet. The extra-large dive door on the starboard side allows for easy access in and out of the water. The HammerCat 45 is the only power-catamaran that offers an entry / exit on all 4 corners. The large hardtop provides ample shade for all guests and the deck lay out can be suited to each individual owner’s needs 

The HammerCat 45 can be built to suit your boating/ fishing / diving / super yacht tender needs.

The hull measures 45’ x 14’ and we have come up with a variety of lay-outs. 
Where Hammer Yachts is different from other manufacturers is that we build in epoxy composite: light weight and strong. The HammerCat 45 weight 40% less than comparable vessels which means we need half the horsepower, and are much more fuel efficient and no need to purchase and maintain 4 outboards! 

The HammerCat 45 can run 50mph with twin 400 Mercuries or twin 425 Yamahas. If speed is important, there is enough room for quad engines. Diesel outboards are also a possibility, this way you need to fuel up only once a season!
