Plummet Mutant V3

[AndersP]

I agree with Harry, When I look down on my heel edge the water releases from the edge long before the sharp corner of the board. The corner makes a deep 'cut' in the water and probably a lot of resistance. I believe the corner gives grip in the water, and maybe it's not a good idea to round it off to much.

Ok team, here's my mutant build picture montage

Lase cut cut/drill template

Shaping the cores

3d printed titanium inserts

Tapering the core top layer

Waterjet cutting the press ribs

Press/vaccumm bag combo

After sanding, a blow out of peel ply not peeling off meant hours of sanding.

Resin coat layers

Finished and ready to ride

Looking good, man! Weren't you going to do an extra kick on the nose?

[plummet]

I have an eccentric rocker. IE more rocker at the front than the back. I did have more springback after pressing than expected so the end rocker is about 5mm less than I wanted.

I've done one session on the board prior to top coating. It's fast, efficient and dynamic. I think it will be an awesome light/moderate wind stormer that bridges the gap to my hydrofoil.
But I think I pulled too much rocker out for riding massive waves. Small/intermediate waves it will be sweet on.

For bigger monster waves I think I will need to make a high rocker version.
Perhaps I'll revert back to my original press ribs for mutant V2 and use this profile.

extra kick on nose is super extra resistance. Even if this look contra intuitive - nose scoop have HUGE influence on board resistance. Kick on nose mean every time you crash into wave board start pushing water. And every turn you dig whole length board in water you push water.

Hmmm, I would say just the opposite - for really big waves you need less rocker, as you want a faster board with more control to get past sections.

Whereas for smaller steeper waves you need rocker, on cost of speed (and somewhat control)

And in really small waves a wider tail.

I was under the impression the extra kick on the nose would be for exactly those times you do crash into the wave.

So that it would push.
Water. Down. Instead of in,
and under water.

haiku!

Cool looking board. The uni in the Z pattern is a nice touch. What weight of cloth did you use? Final weight?

Your logic makes sense Peter as far as wave arc angle is concerned. My thought process is that i care less if i bury the nose in smaller stuff. So I can give away some wave performance for better upwinding and boosting performance. But on big waves i do not want to bury the nose in any circumstance. So i would prefer more nose rocker to ensure that doesn't happen.

But i've only had one 40 min session in pitchy shitty shore break. Now i need to get out there for some real testing.

It does, but it is experience in waves that has lead to these choices, not the logic as such.

Should emphasize that when I say rocker I dont mean nose-rocker, or scoop as it is called.
How much lift in the nose is mostly a personal thing.

It is the main rockerline, and the tail or tailkick that is most important to select for the waves (combined with width and V or not of course).

So using a flatter line/tailkick for bigger waves, to get more speed so able to surf in control on big monsters, and also able to carve around closing sections to get to the clean lip.

And in medium but steeper waves, more rocker or tailkick works fine for hooking into the waveface, and you dont need the same board speed.

For small waves or low wind it is personal as said, a wider tail of course, but whether a more flat rockerline so you can glide a lot easier but need to control your cutback, or you prefer more rocker so you need more power but a he.. of a lot better and smoother cutback, is just a choice.

I assume these characteristics for waveboards should fit the very same on a wave mutant board
