A Different Look

Some quick snaps of the last shell just out of the mould. We are building a series of 10 Katana Marbleheads using a special hybrid cloth. The red bits are Kevlar. No change in structural properties, just a different and unique look. We will keep the boats in stock so grab yours today!

Digital Age

The first batch of our new Swing Rig Blocks. They come in three different ‘flavours’ to accommodate different main boom angles for different clew heights between suits. As our regular followers know, we are always passionate about sharing lessons learned in development and explaining evolving methodologies. For Katana we engineered and prototyped moulds for making […]


The process and resin we are using for our Katana Marblehead are optimised to obtain the best ratio of resin to reinforcement fibres. In practice this means minimising the amount of resin that cures around the fibres which are themselves a fixed quantity determined by the weight and number of layers of carbon fabric put […]

Piercing Insights – Part 2

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 […]

The New Black

Katana Marblehead specimens just out of the moulds. More to follow shortly…

Piercing Insights – Part 1

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 […]

Production Line

Some more images of Katana Marblehead tooling coming together nicely…

Busy Times

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.

Wax On… Wax Off

Progress on Katana RM tooling: Plugs/patterns have been delivered, now preparations begin for taking female moulds.
