I was wondering if someone said add more curve to the tail out line. Does that mean the last 3rd. of my surfboard or just in the tail? And how much curve is good for a squaush tail?
Tail would mean wide point back.
More curve gives you a shorter rail line along the wall, making the board looser and easier to turn, but can sometimes “lever” the fins off the water, causing spinout.
For smaller hi performance waves, it’s usually good.
For bigger, serious waves, it can be applied, but only if the width is narrow for holding power.
Of course, by curving the template at the back, you narrow the tail, which hinders wave catching, but can be made up with straighter rocker.
All part and parcel with length, width, and location of widepoint.
Thanks LeeDD! Yesterday was my first time on this site. Know I can’t stop soaking up information.
Thanks to everyone for the help.
leeDD that was a logical line of reasoning there…i basically agree with everything…
but im not sure if i got the picture about moving the wide point back can lever your fins out???
can you give an example or another description of what you reckon is happening there???

Hi Bert
That’s why I ended the post with the last sentence.
Say you have two 7’6" x 19 boards.
One with widepoint back 5". Board A
One with widepoint forwards 6". board B
Board A would normally have a wider tail, at the 12" mark, but lots wider also at the front foot area, but with about the same actual tail block width.
Ride big waves, Board A would be squirrelly, prone to spinout, hard to bank over at speed off the bottom, sensitive to chop, catch waves early.
Ride small waves, Board A would be sensitive, snappy, quick and easy to throw spray and slash, catch waves early, and feel like a super high performance contest board.
I guess I don’t have to go into the characteristics of Bored B.
In 1970, I had those two shaped back to back, both shaped by the same guy, same thickness, same width, same color, same glassing schedule. Rode both at different times, but owned them overlapping about 3 months.
no problems ,with you there all the way …maybe the comment about levering your fins out ,could have read; lever your fin out…
a thruster would allow board A to have more range…
was the board you were relating to a single fin???coz that was the first impression i got when i read that comment …that why i asked for more clarification .once again you stated all the logical obvious things about the curves of the board …so the fin is the only thing left to account for …
LeeDD from some of the stuff ive read of yours ,youve obviously had alot of water time ,coz your descriptions are very apt and theres no way you could word it like that without the experience…

Hi Bert
yeah, that was in 1970 or so, both shaped by Bob Wise…single fins
I’ve also had Steve Morgan Brewers in a match set, one with widepoint about 4" forward, one with widepoint about 4" back (boy, that one took forever to get, as Steve resisted to the very end to shape such an “abomination”. Those were tri fins around 1983…both 8’6"ers.
I’m an old fart ready for the pasture, but trying to put it off as long as possible thru the help of the internet.
