Hybrid !

I was thinking more the cheeky little wings of a  D Class Swedish sailing canoe.

You want  minimal length winglets really... all other things being equal.  1) Capsize recovery is made so much easier if you can go over the hull in front of them or any larger wing for that matter (ie stay dry if you can !) 2) If you do end up in the water it is nice to be able to pull yourself back in over the minimal width rear quarter.  3) Off wind you don't need the hiking position produced by a winglet in anger like you do going upwind - also Hybrid is relatively long, and the mast is further back than most and more raked than most - you are never really fighting with this hull to keep the bow 'up' offwind - enough buoyancy in front of the mast in summary.  4) Lastly in racing boats - if you really don't need 'it' for any real reason it is just dead weight to drag around plus extra potential windage.

Doing development this way .. trying and then modifying, if needed, without short term commercially driven time limits is a revalation really.  Compromises / changes are not time pressure related so you can keep testing and prove and then hopefully improve.  Looks like Friday PM (tomorrow) is next wet test....
