Wing & Foiling Tech Talks - Aluminium, Carbon & Quickmount Masts 

17mm thick for the dlab? Crazy thick

Thick is stiff and with stiffness comes a lot of control and this is a design parameter which is very important for us. Secondly, thickness doesn't say much really about the drag generated by the mast. The chord length has a much bigger impact on the drag coefficient, as well as the profile you pick. Picking a thicker section allows us to make a hollow mast which is very light, our 82cm dlab mast is only 1.54kg We feel that we have hit a very good stiffness to weight ratio with that 17mm profile. We definitely aren't excluding designing thinner masts in the future, but they will for sure be heavier if we do, as we will need to pack them with more carbon fibre to achieve a similar stiffness.

@@BonieuxJerome love the comment Jerome, thanks for sharing. It’s interesting that I keep hearing foil designers saying thickness has a bigger effect on drag than cord length.
