yep silverback ,your reasoning is sound there…
widest point back , makes a longer board surf shorter ,widest point forward makes a board surf longer…
the length of the tail determines the arc of the turn ,
ive seen a guy ride solid 10’ surf pitching monster truck barrels on a 5’-10" ,it had the widest point forward , like a mid seventies board …coz the tail was longer it drew long arcs and drove solid bottom turns around sections …
i have a good friend i often travel with , he always trying to get me to go extreme wide point back …4 " is as much as i will do …
his last one was 7’-6" with the widest point 4" behind centre ,
the length gives him the extra paddle , but because his widest point is back , his board really has the tail of a 6’-10" , in 3’ waves ive seen him go 12 o clock on the reos , because hes working off a tighter arc in the tail outline…
i had an 8’ performance longboard set up the same way , some times in 2’ surf i would be going crazy real tight top to bottom snaps , then all of a sudden i would bury the nose coz it stuck out so far , my first thought was " o yea , forgot i was on a mal"…
like you thought silver back you actually focus the sweet spot in a smaller area of the board ,so you set your feet and forget them …
as long as your rocker and fin setts harmonise with the package ,
if your going to set up your outline to surf tighter off the tail , then your rocker and fin setts plus bottom contours have to be sett so it all works together ,
if you run to much tail rocker , it will bog when standing on the tail…so straight away you would have a conflict of interest…
i would probably blow the center out to 20 1/2 …ill just run out the back and click my all time favourite small wave board,had this one six years and cant top it waist to head and a half…stats …6’-9" x 20 1/2 x 2 1/2 , tail 14 1/2 , nose 10 3/4
the widest point is back only 2" but it carries the width into the tail…it may be 14 1/2 at the 12" mark , but its about 18 1/2 at the 18" mark …
i would question the thickness ,this one has had the deck pounded into submission for the last 6 years …its barely 2" now …
the bottom is clean not one dent or mark…the deck is a patchwork of 5 minute araldite , slackass gota get back in the water repairs,ive come unstuck on some air landings and punched right through the deck…
all i have on this board is 2 oz either side of the wood…
it floats in the air if you drop it flat…
low weight is part of the magic in this one …
