Growing
We now have an opening for a composite fabricator/shipwright. Our workload is growing so we would like to take on another team member.Projects include UAV airframes, customer parts, RC yachts, and our A Class catamaran.A good mix of one-off prototypes for R&D, and production items. If you possess skills in carbon fiber pre-peg […]
Tamahagane
Another symbolic milestone: the last batch of Katana Marblehead hulls from the existing tooling is here. The old moulds have been ‘retired’ and work will begin soon on updated tooling. Deliveries are expected to start again in mid 2015. Get in touch for more details…
While You Are At It…
Katana M in orange Durepox (same paint as the latest A Cat)…
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 […]
Glossed
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 3
We saw in Part 1 and Part 2 that generalised statements about the handling qualities of ‘wave piercing’ bows miss the point that bow profile is a reflection of sectional volume distribution, which is a much more useful indicator of design priorities.Multihull bow sections have recently tended to carry volume lower down rather than above […]
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 […]
