Yeah those greenough fins suck, I've got a few and I hate how you can do hard fast carving turns on them when you're trying to go straight really slowly.

The standard greenough fin is ok, I rode them exclusively for the first 21 years so I know what they are like. Once going to more upright planshape fins with longer chord in '94 there was no going back however.. the low reynolds number of the greenough type vs the higher reynolds number and lower induced drag/higher lift of the 'spitfire' type? No competition really the spitfire type wins hands down.

The BLEF foils are another huge improvement.

Regarding fin flex in a Greenough type fin it only reduces efficiency as the flex is predominantly in the wrong plane. A long horizontal tip with high area is needed for correct fin flex.

What sorta coin we talkin' for 3d printing infrastructure Roy?

Roughly nz gdp?

In this case about $50k.

The ultimate is going to be 3D printing of complete surfboards in one piece using graphene... harder than diamond. 200 times stronger than steel, light, and flexible. Currently graphene is $200,000 per kg. I can't wait until it becomes possible, it will be soon.

Grammar old sport, it should be "who ARE we?"
I've signed a 9 page non disclosure agreement with one of the companies I'm working with so can't say too much. 'We' also refers to my business partner and I.

Good to see you persevering with the overly opinionated unfounded pie in the sky theorist persona ... it goes so well with your pink jumpsuit and tinfoil hat. Get a mirror.

No, pricing will be in the normal range for foam boards.

Congrats on new little one.

Oh I just found that the 70's singles had to be nursed through bottom turns, they'd get to the stall point pretty easily when pushed.I used to re fin some of mine as the foiling wasn't so hot, replacing them with fins from Wayne Parkes, they were pretty good.

Once going for slightly thicker fins with higher reynolds number and ellipticaI plan shape I didn't want to go back.. just opinion based on the past 40 years, you don't have to agree, but hydrodynamic theorydoes so I don't mind if you don't.

Trying to get my head around graphene Roy....

If graphene is considered a 2 dimensional substance, how can you 3D print it?

And can anything really be considered 2D?

Hazzard as may half guesses as you like. Hey I bet the late Dennis Fergurson fiddled more kiddies than the rest of us ... but it doesn't make his views correct ... does it.

There is absolutely nothing wrong with walking the path less travelled. The world needs people like Roy ... he's the yin for ya yang so to speak. I wish him well in his endeavours. And yes when I say endeavours ... I do mean large hulking wooden vessels.

God speed to you Roy baby ... keep it moist brother ... and shoot that curl ... yeowwwwwwwwww.

Why does Roy use the term "hydrodynamic THEORY" instead of "hydrodynamic FACT"?

The term theory is used entirely correctly.
