210 x 56.8. Ofo irrelevant since you are standing so far back. Relative to your back foot corresponds to a 32-33cm ofo, despite looking like an ultra wide tail.

If it works an if we think it will appeal to enough people, we will certainly make bigger ones too. But at least for now, it is a concept intended to by used as a "normal sized" wave board rather than an ultra large one. So this 75, is made for me at 70kg. As all Simmer boards, it is very lightly driven though, so for purposes of "dynamic lift" I don't need a bigger board. For purposes of "floatability" some people could of course want bigger relative their weight, but designing one that is intended to be used, say, 15l liter + would require some things to change (most notably rail flow).

For the point of discussion: how wide would you like such a 100l board to be?

Fins: It is a five box. 10cm slot boxes in front and 3 13cm one in the back. So far, I've run it with big front fins (12 or 13cm) in both quad and tri setup (2x11cm or 1x14cm in the back). I'm gonna try in in the more traditional quad setup (small fronts) too as well as a twin, but it is designed to work best with the setups above and (like many surfboards nowadays) be tunable on the "pivot vs carve scale" by means of changing from a center back fin to two back fins.

Ola, if you weighed 95 kg, what would the board have looked like?

yes 220 cm 62 cm and 100 liter ! perfect !

might help with ideas, I have the 88L one and it rocks...

Yeah. AHD always had a knack for the odd and extreme. Just look at http://www.ahd-boards.com/models/afs-1/en

I rode the Seal many years back, but didn't really get on with it. In fact, a more direct inspiration conceptually speaking was the old (2001) or so Starboard play. Remember? Far longer, of course, but I just liked how the concept came across at the time.

To keep you all updated... protos for two bigger sizes are just about ready. Overall I'm super happy with the 75, but it is perhaps a bit too slidey off the top (or better put: it grips really well when railed up, but I want it to enter that grippy type of turn spectrum also with a bit less angulation). So for the next protos I have made some slight adjustment to the outline curvature on the rear part of the board as well as thinned out the rails in the back part a bit and also added some more pronounced release to the rail. We'll soon know how that works out. But even the current board becomes MUCH gripper and more "back footed" in feel with a "trad" quad setup with small front fins. As mentioned, the board is amazingly tunable by fin choice.

Below is some pics from a side/side on day. It's really easy to come in under the lip and "fit" the board into a tight turn (pic 1) and the floater style top turn in the second sequence is a pretty good illustration too, I reckon.

I will let you know once I have finalised the bigger ones. I promised to deliver the filer to the builder this weekend, so not far away.

I got some pics from another session on the board from my friend Robert Koste. No too shabby in the carving department, despite some theory perhaps saying otherwise... (this is with the 2x14 asym + 2x11 sym foils that actually felt a bit sketchy relative the more traditional quad setup on the day in question. The patter setup adds even more on the carving department).

Also notice how speed is kept in this rather "full" turn". I reckon this is an interesting aspect of this design. Despite turning relatively tight, the tail will not push as much water so you burn less speed.

ULTRA rainy when the pics was taken,so good job by Robert to get the pics this crisp.

Still at the builders. I reckon around three more weeks.
