I have recently acquired a Barry Bennett 9'4' x 21.5" old log [mid 60s] that would have had a D fin in it I assume [but I'm not sure]. I'm looking at putting a new fin in it. What would putting a big swoopy fin or a hachett style fin do to it's ridability compared to a D fin? It's in pretty beaten up condition so I'm not over concerned with originality, more concerned with rideability.
cheers

if your concerned about rideability only and as you said its fairly beaten up i would deffinetly recommend going a greenough type dolphin fin. if its a big fat heavy type barry bennet board then get something nice and whippy as you will need it. Unless you're familiar with old logs and into that type of board i wouldnt go putting a D fin back in it

Those old D's are tough to turn unless your a 140kg rider..A dolphin fin would look original..BUT.

Go with SPAZZ..those fins will work better.

Thanks for the replies...again I know it's not original, but I'm thinking I could put a fin box in it and experiment.....I could put the 12" Greenough from my modern log in and see how it goes..and decide from there??..that might be fun and educational

I would never question what BS has to say on these sort of topics. He has seen and ridden and owned more old style long boards than I have ridden longboards. Its a no brainer.

The problem with the old D fins is that they are too thin and are basically flat sided. Foil 'em right and they are all good, much better turning capability whi;le retaing the old look. We have some coming up with top notch foil options.

Horrendous flat sides in the base and a very low Reynolds number. Not ideal at all sorry.

A well foiled pivot fin would be better.

Looks can be deceiving as the surfing population have all been trained to expect a certain look... this is a ball and chain to performance.

That's way too thin, they should be 18mm minimum at the base. It's basic hydrodynamics.
