Howdy Satch,
What are your dimensions? How good do you surf? What waves you wanna ride?
I can only speak for myself:
- 2 inch tail is pretty low for a hp surfboard, i made a 6ft12014.8 tail with 5 inch nose + 2 inch tail rocker with single to double
The board flies! over 1-2 feet waves, but once the waves get a little higher, say shoulder and above [i am 6ft1 1m89] it has a harder time turning
btw i set the fins 3.5+11 off tail, aimed 1.5 inch perpedicular to the nose [to the side] and set fins at 7degrees relative to bottom concave
My advice if you are my size:
add 2.25 to tail, make nose rocker 5 inches
do single concave and 19.5-20 wide, but make tail a tad wider too: 15inch or so, if you want a little more release from the tail because it is so wide, add a swallow or moon tail.
BTW if you want flex, decrease thickness throughout the last 18 inches in tail and nose more than you did.
Is the thickness of 2.25 you ultimate thickness? If not, then take out more thickness down to 1.8 1.9 inch, then add the 6 mm corecell. If you do this, have a more flat deck too, dont roll the deck too much, you want to keep as much volume as possible in this shape that is so thin because you want the flex.
What is your proposed laminate schedule? Corecell will break down in high wear areas eventually with such a ligth core, you know, the corecell will flexalot, then break down. Maybe a wood skin on the deck is better, say bamboo, but then add thickness again
aaah, building boards is great
show us pictures, too little build threads…
