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 […]
No new interesting images this week since parts are on the road and other projects tick along in that phase where a lot of work takes place but the visible differences are small…For now, here is a video of the Aptec CNC machine at work on the A Cat rudder plugs. Thanks to all our regular […]
Machining of plugs is complete. Next week they will leave the Aptec facility. After a few days in transit lamination of the female moulds can begin. Our decision to invest time and resources on highly detailed plugs should hopefully make the next steps more efficient.A few words on what you can see in the images: […]
Recent consultancy work on the Carbonix side of CarbonicBoats. Once again, we are not allowed to show much given the nature of the project (UAV with defence applications – think a six metre wingspan bird). There are definitely interesting parallels with foiling sailboats, especially with respect to dynamic stability.
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 […]
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 […]
Katana Marblehead specimens just out of the moulds. More to follow shortly…
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 […]
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 […]
