Yard & Construction:
The HammerCat 35 is built at the Carbo Tech yard in Cape town, South Africa, a boutique boat yard that is specialized in light weight-high-end yacht-building.
Uwe Jaspersen is a well-known figure in the south African boat building scene, he is the original founder of the Southern Wind boat yard, and is responsible for dozens of new build yachts and catamarans, amongst which the 62’ series Gunboats which are now considered the pinnacles of Gunboats.
When building a power-catamaran, weight vs strength vs cost is of utmost importance to the builder and end-user alike. Very few boatbuilders achieve what Hammer Yachts and Carbo Tech have accomplished with the HammerCat 35: a fully decked out sport fish power catamaran, complete with fuel / water / 2 x engines at 3.5 tons / 8,000 Lbs
How do we do this?
We build our HammerCats using the most modern construction technologies, not commonly used for pleasure vessels but mostly seen for building racing yachts. The e-glass and carbon composite structures are vacuum fused, incorporating solid PVC core (Mycell foam) and Gurit top of the line epoxy laminating systems.
The core panels are machined from templates to ensure acute and repeatable sandwich structures. The entire structure is compacted and bonded under vacuum. Bulkheads are vacuum-laminated foam core structures, bonded into the hull structure with high strength epoxy compounds before being tabbed in using a glass/epoxy laminate to ensure best possible secondary bonding reliability
The hull cavities that are not utilised for storage or hull access are fitted with XPS foam (waterproof closed cell foam, a total of with 4m3 / 43 sqft), ensuring that the HammerCat 35 is unsinkable. These foam filled inner-compartments are sealed from all sides.
The fuel tanks are manufactured from ¼” Marine grade aluminium, foamed into the hull and then sealed in with an epoxy laminate to avoid unseen seawater penetration, which, in the long term, could lead to corrosion.
The hardtop and its supports are entirely manufactured from clear carbon fibre – making it by far the lightest and stiffest T tops in the market, and then we are not even talking about the looks of the 100 sqft of clearcoat carbon fibre hardtop, larger in area than the carbon roof on a Porsche 911!
Where metal fasteners are utilized, only Stainless 316 is used. The HammerCat is built to NMMA requirements.
The HammerCat is unequalled in design, performance, construction and safety and destined to be the benchmark for the next generation of power catamarans.
