Has anyone tried the $200 Greenough Power Blade fin?

[michael]

any info on how to size the PB fin? For example what size for a 7'6 hull?????

From my understanding... Inch per foot. Try 7.8

I recall reading that the shaft is made to be stif while the blade is flexible Kind of like a rudder on a boat. When you turn the blade turns with you.
Never tried one but I do have the Greenough stage six. Used it in my 8’6” Bruce Flowler Platapus Lots of drive out of bottom turns.

Game changer in edge board under 7’

I have the 8.5 Powerblade on my Andreini 7'6 Vaquero Edge. Super fast and gives you "grip" to make quick turns. Feels like a 2+1.

Why all the hype and high price point when you look at the plan shape and the materials. Is that fin harder to make than a cutaway fin or one of Guy T’s Manta fins? G10. Volan. Etc... It’s really about the foil more so than the material. Though good for them - what fins should cost.

Jim made a custom wood fin for a furniture builder. Spec’d to his materials request as well as length, rake and base length. It took two-ish months with his heart attack and the demand for boards to finish it. Guy filed a claim with PP that it took too long and wanted his money back.

Attached are a few fins from the late 90’s by FU and TA. $45 a fin (then...not for sale). What is that odd looking fin on the right...could barely give them away back then.

Terry, Marc A recommends power blade fins on edgboard set ups. Had one on my Leenough edgebard and it worked incredibly well! Tons of drive and speed and no loss of speed in my turns. Might be a good idea to borrow one and see how it works on your board before dropping coin on one. Ask Mark S to borrow...he has my board. Good luck!

Yes, unidirectional (base to tip) layup, apparently.

I don't know if the fin is actually harder to make, but the uni-directional cloth may add more time and it's also made in the USA. There is quite a bit more flex from side to side from what I've seen in videos, like a rudder. I don't own one, but others who do can verify.

Correct. The base / stem is stiff, head alone flexes left and right.
