hi 'rh' !!
it will be dependant on your paddling power , the waves , your size , and other variables of course .
how wide were the nose and tail on the kane garden ?
what is the rocker like ? rails ? bottom ?
for me [i'm 5'9 and 63kgs at the moment , and mainly ride beachbreaks in the ankle to head-high range [which get bigger and hollower SOON !] ,
i've only made six of these type of boards [fairly ] recently , but i LOVE them !!
[this is only me , but...] on my more recent stubs, i now prefer a 4-6" [max] fairly square pod , nice rocker , vee, 5'10-6'2" . my next one , i'd like to go with 19"-19 1/2" max width [i found 20" a bit wide , for when it gets bigger and more hollow [ie: autumn and winter], here] . i started off with flat bottoms and hard edges all the way round , on my first two , by the way.
the next one , i'd want to make 2 1/4 " thick , as i found that 2 1/2" was just too thick for my light weight , on my recent orange stub [see the 'from mutton to nearly lamb' thread]
and i differ , in that , besides a fin box , i also like being able to have the '2+1 ' / 'widowmaker' option , hence , probox side plugs , set around 11" up from the tail .
the finbox i try to have fairly close to the pod [tailblock] , in order to be able to get thruster-like fin positionings.
....anyways , that's just my personal prefernce / experience , others may vary !
.... i hope this is helpful ??
cheers !
