As we’ve seen in previous posts, conventional hulls resist bow down trimming forces by immersing more volume forward. This shifts the centre of buoyancy forward. If the centre of gravity remains stationary or moves aft, the resulting separation gives a bow up righting moment.Tornado style ‘conventional’ raked bow profiles indicate flared hull sections. Meaning the...Read More
We are receiving many questions about the pros and cons of so-called wave piercing bows. There seems to be much debate among sailors, partly fuelled by unsubstantiated claims from manufacturers.As our regular followers and clients know, at Carbonicboats we do not make dogmatic proclamations about what our products will do. Instead we explain the reasoning...Read More
More progress on the A Cat hull plugs in Far North QLD… The stable and durable yet relatively economical material chosen requires sealing of the final release surface. Skilled hands are needed to do so without altering the machined shape. A final pass in the machine ensures the shape has remained true before painting with...Read More
Bonded or Mechanically Fastened? Most current A Cat beams are bonded to the hulls rather than mechanically fastened. With some increasingly rare exceptions, builders and sailors prefer a unitary platform. The downside of this choice is arguably reduced practicality for transport since the platform cannot be dismantled into its component parts. Accepting this compromise...Read More
A Class catamaran candidate hull shapes in one of the final evaluation runs. The chosen shape is now finalised. Detail design is next as virtual models are being prepared for machining…Read More
Progress continues on RM tooling preparation in the workshop. In the office the A Cat design is approaching completion. R10R and IOM developments are in the pipeline and consultancy work continues on aerospace projects.Read More
