Hey Gang,
I sent Steven the drawings for these awhile back, and he sent me some prototypes to verify last week.
I developed these for my IM31's prior to the 2012 Nats after having issues maintaining the proper "ride orientation" under race conditions.... (In other words... I couldn't keep the boat from FLIPPING in race water in the turns!! )....
The stock, teardrop shaped turn-fins don't hold. I built a couple of sets of these new designs and it transformed my IM31's to a completely new boat. Literally a night-and-day difference. Boat is more stable in the straights, and holds the turns in rough water, and under a good head of steam.
As soon as Steven has a link for them on his store, I'll post it here (or he will)... They are a bolt-on, and have a bit of depth adjustment as well.
A bit of a design flaw on my part... these will correct it!
Nicely done, Steven!
