With my windsurfing head on, or i14 (total shitfight) head on, as long as the sheet isn't cleated or snagged, you can do an awful lot muscling/paddling the boat round so that it is at a nice heading to re-enter.

Plus, the "module" that the mainsheet / toestrap is terminated onto is well off CL so much easier to grab than the toestrap itself.

I agree with Washy71 on both technical and commerical matters - I am happy with the boat without grabrails, otherwise, chances are it would feature said items.

I am fairly sure that processes are in place to get boats to the states, undersanding that it is a far tougher (by which I mean expansive) territory to service than the UK and mainland europe.

The main value of the grab rail in the laser is a light wind toestrap. Don't think it is necessary per se for recovery.

That said the punk prototype had very nice teak grabrails, and dagger and rudder grab handles on the mk 1 foils.

There could certainly be some latitude allowed in class rules, although it would require some coordination with the builder in order to ensure that backing pads are located on the cockpit sides.

ChuckLinn have you emailed Rodney Cobb? Think he is Rodney53 on this very forum.

There is one boat in NY already as far as I know.

There are some folks who believe in an end plate effect so they like to seal the lower edge of sails against the deck.


Which only works if the sail is actually touching the deck. If there's 30 cm clearance, might just as well make it 90. 

Agree re: endplate effectiveness, but there is also the consideration of the distribution of area in a type of boat that is very RM limited - nice and low and you have plenty of drive with minimal RM penalty.

Hi Bruno,
A large dead rise angle on a pure planing hull will increase drag and improve comfort.
What we are talking about here is comparing to a traditional semi displacement round bilge form, I.e how you get from the keel to a chine that necessarily needs to be above static waterline most of the time - ie to reduce the curvature in the transverse sections (as well as reducing rocker f/a, all in the name of reducing dynamic squat) then you have to have a deadrise.
14 spends maybe 60% in semi displacement the rest in planing depending on where you sail.
Trick is to be good at semi and planing work, with some conflicting demands!
