hints for rocker on an eps gun

so i have ythe foam and very occasionally we get the waves.

Im 67 kg 174 tall.

6’6" 18.5" 2.7"

around 32 ltrs

its gunna have rail channels, ala Huck and stretch boards.

My eps is light my glass will be solid.

 

The big question is, i have been looking at a few rocker pics around and at the moment i have 5" nose and 3.2" tail rocker. Is that too much?

Im on the sunshine coast. East coast of Australia, typically week waves but this is for the rare big cyclone swell to light up the points and help me get waves in the croud and still do good turns.

At the moment its still and idea and a file on shape 3d, i have to transfer the points to a hotwire template and mow the foam way down the track but as you may have seen with the cornice thread, ideas fester inside me for a good period of time before they come to fruition, but thats just how they work with me, nearly finish a project or two and start thinking about another two…

I’m generally basing it off one of robin mair’s magnificent machines.

see pic.

2.7 is thick - 5" is low - 3.2 is high - just my opinion

2.7 thickness is OK,  5’’ is too high (4 1/4th),   3.2’’ way too high (2’’ max).     Like others, just my opinion.     This is a gun, right?      You do want to go fast, yes?      The above dim’s will deliver that for you.

For 6’6" hollow wave step up (indo, hollow french beach break) i go around 5.5 for nose and 2.5 for tail depend power and style of rider. Flatter than that for flatter waves.

tit’s fine for our waves.

but… a 2" of tail rocker and a nice single fin might make you surf like a pork chop. Bog those rails… sunny coast waves sound good mate. We don’t all have sunset in our back yard.

Rip in.

Baahahahah

I will see how I go, maybe reduce them both a smidge.

But yes sunny coast waves are average.

Most of the time.

some sound addvice and some titty pic and I get a ‘-1’ wtf… ?

I just 1 + you. But the pic has gone. But I didn’t do it.

Ideas so far



Looks good!

rocker looks long and straight out the back half mate (pull the ballance point back 2" or so) 

 

…the important stuff is at 1 and 2 ft from nose and tail…

check for 1 inch 1ft up the tail and for 2 3/8 1ft down the nose.

Like yorky said. And more on that. Your rocker is too continuous, you need a bit of flatness under your front foot out the mid. If you have a parabolic rocker the board will paddle like a turd. What will happen is the minute you stop paddling… The board will stop moving. It will have zero glide. Sounds like fun, right! You paddle for a nice set wave, and right when you want to get up it bogs down and hangs you up in the lip…ahhh good times, I’ll bring the camera…Look at robins rocker, then look at yours… And yes 3 inches is too much foe a 6-6 board. Ok for a 8-6

 

I dunno if this helps, but here are the rockers side by side

 

nice going Huck

 

Nice,  see how the rocker accelerates out the last 8 inches or so. It’s very subtle, but if you look closely you can see it…and if You could feel it, it would feel like like a 5 gallon bucket of rail water being thrown in your buddy’s face when you cut back. But the mid section of the board is very controlled, nothing parabolic. Just a smooth rocker with no weird  flat spots.
