Laminating main hull part 416

The aft part of the port under wing area is laminated. It's just the middle part and the bag left on this side, postponed due to a bad bag experience lately....


Recess for the external safety compartment hatch, has to be incorporated in the last laminate on this side somehow.


Starboard under wing area is almost fair enough for lamination


I laminated the bow area last night building it up with several layers of carbon under the hybrid cover. It will be very beefy. I hope I will never know how big floating lumber it takes to break it.


At last today a teaser for the true sailing nerds: I've decided to make my own carbon wing mast in the moulds used years ago for the Formula 28 trimaran Mirage. It is kind of funny to see how all the boats on Derek's Trimaran cool blog have this kind of mast. I received some cut off's of Mirage's mast today from the designer and builder Per Ferskaug. Quite impressing to actually see the dimensions of this air foil, chord 57 cm (22") with 19 cm (7½"). The picture shows the middle part of the spreaderless mast, as seen in the video it tapers towards the ends. The challenge is to build this mast without a weight penalty, as the aerodynamic properties are superior, and the absence of spreaders a very tempting property. Carbon comes in all kinds of qualities, and ditto pricing. I'm currently investigating trough Silas Spence how we're going to do it using Toray's M46JB fibres which are kind of middle of the pack in High Modulus fibres, being ~90% stiffer and ~20% stronger than the regular commercial fibres that I use in the hull which in turn approximately doubles the properties of regular E-glass.


I'll be "out of office" for a week now, due to a work related out of town intermission. I'll probably be able to go sailing a schooner as well....
