…well Yorky,
Sometimes I prefer to put headlines (guidelines) and the rest let the guy figure it out…
I see some confusion with the side runners, here some insights
-thought due to a lot are clear glass and the “leftover” edge let by the glasser blends perfectly well with the fin
so most of the times seem that the fins are longer
-some dims are provided for the boxes and not for the glass ons
-not the proper fin area
-not the right template
-boards done by people who really don t know about it
-most bonzer don t have overlap
“a few” have 1/4 as too much
the side runners are not exactly fins
I mean, basically they are but not for what a fin is intended for
so they re side runners to redirect the water
a bonzer is like a single fin with muscles (and more lift)
so think as a single fin with all the looseness of that
and not as a thruster/quad type
the main fin has a 1/4 overlap into the rear of the back runners (not counting the glass rope)
this let 5 1/2 for the small boards with 6" fin , 5 3/4 for a bit taller board or 6 1/2 fin
for bigger boards up to 7 is 5 3/4 - 6
for 7" fins is around 6; 1/4 more for bigger fins
I keep the distance for semi s, guns (narrowed boards) and lboards
but you can think about them
is somewhat similar than the thrusters
—talking about Hamilton
well, the guys is a big name in the industry and good surfer
also seems a cool guy (but I don t met him personally)
but I dunno about the shop
why?
because
some guys from here worked with him and I know these fellas
and they dont have good products and Hamilton talked good about they work…
so I have my doubts.
One is a longtime boardbuilder (Damiani is the last name)
that worked like a year or may be more with Hamilton
plus a kid that have the brother living in Hawaii, and went couple of times there and Hamilton
gave him a job (in first time I thought was coolness) but let the kid put the fins…the kid barely can do a ding repair…
so, all the previous pictures of Hamilton s board don t look right for my taste
and for international standards of quality and most important, for quality design
–regarding different tilt
I did a few
but in that case you need to think the fins as real fins (in design)
so you need to go with more than 1/8 thickness and foil
I did with 1/4 and 5/16 thickness
In my opinion, work better in small boards (small volume too) and radical surfer
not so good in semi s or like that
but I prefer equal tilt for the side runners
few years ago I asked here about opinions to double foil the back side runners and let the front ones dingle foiled and with less thickness
Imagine one large fin like the 3 ones, but with thickness increased backwards (so tapered out to front tip)
but splitted like the 5 finned
I don t had a response here
then I forget about it
and all the rest of the bonzers that I did/do were/are with the same thickness for all the siderunners
sometimes with single foil sometimes with not too much foil
depending the final use.
