HammerCat 45

Fast, Luxurious, Light, and Fuel Efficient.


HammerCat 45


The HammerCat 45 is the second model of a new generation of power-catamarans. Built by Hammer Yachts in Cape town, south Africa, the HammerCat 45 features a sweeping “Carolina bow” and lines that make her look going fast while sitting in a marina or at anchor. The HammerCat 45 combines her good looks and sleek lines above the waterline with a very efficient and modern underwater body, featuring a double stepped hull, a wave piercing bow and a high tunnel for optimal performance and comfort.


Designed by Robert Quinn (designer of the HammerCat 35) & Hammer Yachts, the HammerCat 45 is designed to be a multi-purpose vessel: the HammerCat 45 can be built as a day-boat /cruiser, sport-fish, dive-boat or multi-functional super yacht tender where all of these attributes are combined in one superior vessel without compromising functionality. The HammerCat 45 follows the same hull design / lines as her smaller sister, the HammerCat 35 with a Carolina bow, curves everywhere you look and timeless lines.


The HammerCat 45 is semi-custom build: the hull, center console and hardtop are standard, with an airconditioned cabin / shower / head area forward of the helm. We can customize and build a HammerCat 45 to your needs. For a fishing model we can include a fighting chair in the aft cockpit area, a side door, a marlin door aft, outriggers, live bait wells and tuna tubes. For a dive boat we can build in a compressor, a large dive ladder (or two) , more seating and more shaded areas. For a super yacht tender or family day boat we can build a dining area, more lounge areas, or more seating. Or we can build a HammerCat 45 that includes some items of all of the above. You decide, we design, and we build.


The collective experience of well over a century in boatbuilding and systems engineering resulted in the HammerCat 45 setting new standards for optimal performance. Built using an optimized combination of epoxy composites, carbon fiber and high density-structural foam, the HammerCat is much lighter and stronger than other ~45’ monohulls or power-catamarans. Twin 5000 Mercury engines will push the HammerCat 45 effortlessly to 40 knots, with the option of selecting twin 600HP Mercury, these engines will bring the speed into 50’s and up, while maintaining a superior fuel efficiency and smooth ride. We also designed the HammerCat 45 in such a way that we can accommodate Yanmar 440 HP inboard diesels combined with Konrad stern drives, making the HC45 a great support vessel / tender to a super yacht as she won’t carry combustible fuels, and the range will be exceptional.


The standard equipment on the HammerCat 45 is impressive and offers a very complete mini-yachts, ready to enjoy. The extensive option list offers any experienced or non-experienced boater / dive aficionado / fisherman / family an almost endless variety of options in terms of electronics packages, engine packages and comfort features. As a boutique boat builder, Hammer Yachts offers an unmatched flexibility when it comes to option choices.

The HammerCat 45 offers you the choice to use the vessel to take your fishing buddies on a trip one weekend, do a family outing for 20 people the next weekend, and take your wife for an anniversary weekend all in one boat! Seating for 10? Fishing? Diving? Barbeque? Cabin & head? You don’t have to choose, all the above are a reality on the new HammerCat 45.
