[double foiled single fins , as twinnies …]
With Akila Aipa’s mentioned narrower tip . [In a ‘Surfing’ mag article recently , commenting on modern twins he has been making for dave rastovich]
If I don’t get to try them , hopefully Pascal [‘popeye’] ‘may’ , in his ‘Speedneedle’ fish , some time soon ?? …
[* LeeDD used to write about narrower based deep twin fins , in the 1970s … it got me interested , ever since !]
…to be continued , hopefully …
cheers !
