I note the more developed prototype seems to have a nice carbon boom and GNAV. Makes sense to me. |

Having been smacked square in the face by both types of boom I can assure you a carbon boom doesnt hurt anywhere near as much as an ali boom. I barely felt the carbon boom, the ali boom gave me concussion for 3 days.

What stops the moving pole munching the kite into the tube?
When your kite is as old as mine, it sticks to things..... |

I'll defer to your great knowledge of being smacked in the face by a boom!

bloody hell you lot! Is being hit in the head really a genuine issue when choosing materials for boom?! You need helmets. Or padded booms!

Don't get too excited by the alloy boom ...
production boats would almost certainly have a carbon one as default. The
test being run was actually to compare/contrast the boat with a GNAV first and
then conventional kicker - they don't run on the same booms of course and we
just had a spare alloy tube lying around for the 'conventional' testing.
Both work fine. Both could also be an option but I suspect the overseas
market involved will simply opt for a standard GNAV - I'd prefer conventional myself,
there is plenty of room for the crew work anyway, it does not disturb the
mainsail setting as much, is less complex, lighter and of course cheaper.
BTW Jim has identified some of the features and considerations rather accurately. The spinnaker is cut with a high clew to aid visibility - hence the first block each side being further back than otherwise ... The pole also exits at an upward angle off the bow for the same reason (and if you look carefully you will see it largely sits in a recessed guiding channel under the foredeck to get a decent angle). The deck mounted jib cleats are there to keep them out of the way really (off the floor) although in a production version they will be partially recessed in the edge of the deck - not mounted on the surface as in the photos. The 'white’ sails (main/jib) are smaller than their Icon equivalents as this boat carries that 3rd sail - and the boom is higher on the mast which is itself slightly shorter. The concept is to maintain an easy to manage boat that gets its pace from a very low resistance hull and relative lightness and that can be used across the wind range. It points impressively high and the helm balance is great already so the basics are right for sure .. but we are still working on all the important details that remain. The spinnaker in particular will get a lot of attention very soon so when we do screw it up, as we will, at Burghfield in the next few months expect to see a few photos of the bright yellow thing here. We will also be asking a few outside the project to give it a go ... you don’t want to end up believing too much of your own propaganda in this game. What stops the moving pole munching the kite into the tube? The spinnaker is stored/gathered within a generous sock - the pole is underneath the sock and is anyway channeled in a recess.

My question about the jib fairlead positions was really curiosity about whether it makes it hard to get the vertical sheet angle right? Do you just deal with that by moving the tack up/down?
I quite like the idea of the cleats being in front of the crew rather than astern as per the 400. Bit curious about the big lump of shiny at the back of the chute? Surely that could be lighter and cheaper in GRP? Or do we need a bit of chrome for some markets? :-) |

Neither IMO both were unexpected gybes so the boom came across very quickly (one was running by the lee in a Laser).
