Here you go Brooko,


this is my design for a 7'10" supa board for heavy weights it has 140 ltrs volume. I know it says 8'0" plus one eigth of an inch , but this is the planshape and the measurements are OVER THE ROCKER LINE, so it reads longer.

When I design a board I do two designs one is for the planshape and the other is for the correct length of the rocker and thickness profile which is measured over the bottom curve.

Any way this is going to be my next shooter. The tail is a bit wider than the white quad, it needs to be to get the volume I like to ride. The best way to describe these short boards is that they are quicker, not less stable.

Haha.... love how many beers she will hold. Just got back from a really good 2hr session in the surf on the 9 6", 1hr of pure oil in head high waves and 1 hr of slight onshore Did some really good tight turns and starting to be able to whack this 9 6" really good But, in the glassy conditions I was paddling no worries, never falling off and not really fighting the board, the last hour in the choppy stuff was a bit of a struggle, I find I use heaps more energy and tire quicker when Its a bit choppy on the 9 6" Now Rod if you can do a board that turns like the 9 6" but paddles and floats someone around 100kg better than It, I am really interested I can paddle the 9 6" pretty good for someone 6ft and 103 kgs Its just a constant battle, the problem is now I have retired the 11 6" I am probably unrealistic trying to get something that paddles like it but surfs like the 9 6". I am keen as to see your new designs Rod for your little sups, I am not interested in the longboard style of surfing an sup...I want one to rip like the 9 6" but paddle like the 11 6"

Wider...thinner rail profile and a wider tail may give you something like that....rocker prile on Rod's board looks pretty mean!!

Hey guys it has taken me a while to work out the rail profiles.
Basically the flat decks keep a reserve of volume at the deck level and the thickness is out towards the rails so that when you tip the extra volume is there to slow the sinking down.
I have found that roll decks keep on sinking once the rail is under so I don't use them any more for SUPA Boards.
It has also taken a few years to get the thickness profile, rail volume and rail angle right so you can carve in sucky surf.

Thinner rails are real tippy because of the low volume. If you go to wide you can't really get the board onto its rail to carve.

I also use what I think is a lot of V and concave, not to mention tail lift.
The tail lift that I use won't work in standard type mals as they are to narrow for the drag that the extra tail lift causes, but in SUPA boards because they are so wide the extra lift of their wide tails more than offsets the drag and actually lets you carve quicker, tighter turns without the loss of drive when you want to front foot them.

Just touching the surface of design.

Hey Rod what about a channel bottom sub ? a few of my mates ride al byrne 6 2" & 6 4"s and love them ,but not real good in choppy conditions ! Also how many beers is the 9 6" compared to your proposed sub?

Man your funny Rod.. ..either way I love my beers, normally coopers green but at the moment I like james squire amber ale.... So as many of these you can fit into a short board that rips and holds a line in a barrel im keen to have one
