Mate of mine fit the large finns outriggers to his pa and we sailed yesterday in 25kt + winds
I was impressed as - he had the 3m star sail and it went like (censored) off a shovel - its not as fast as the ai we were with but hey neithers my revo - and stability - sheeyit - ol fatboy ray can stand on his outrigger - ive got the large finns on mine and i can push mine under - to flip his yak would be really difficult - pitchpoling down a wave or getting hit side on or suchlike.
The upwind performance was pretty good - i followed him upwind - and it was howling - well over 25kts and looking at the gps he was aiming at 40 and acheiving 30 degree tacks with the sideslip taken into account.
Tbh i was very sus on how it would go if he got caught coming home into a howler and i was impressed
Where we were was sheltered waters - so just a wind wave and a tiny bit of swell but still it went a lot better than you would think.
