Larger fins on Quad

[eastbound]

thx exit--you are quite right re the red and black HI's--unfortunately unable to find

but then thx for the tip on shapers--looks like it may be my fin source ongoing

Old HI-1s do show up on ebay from time to time if you are willing to hunt.

Shapers S 9 do come in twin tab with a plate and screw center. Also Von Piros V 8. HI quads are interesting - have a set which worked really well in an SIC a long time ago.
My own experiences with tippy wan ken obi led me to conclude that quads that were deep did have a noticeable stabilizing effect while paddling and wider keel type fins did not. GL quads tamed my Rawson. Pat liked AMT quads.
Back in the day, both of my Rawsons came as quad only and the deeper GL and HI helped with paddling stability and those boards ripped.
Controller and keel profiles did not  agree with those boards.
That's why I have a ridiculous collection of fins. Every board responds differently and it's all part of the fun.

Love the Harley Ingleby on my smaller boards 7’4” not for the stability but the drive.

Looks like they still have them available.
