Thanks Ola, nice.
Than this maybe would be my board! I have the freegal 80 and often I wished it would be a bit less in width. One cm or so. I'm 65-68kg and for me the freegal 80 could be a little bit easier to press through a tight side onshore top turn.
I run it as a trifin with 10cm K4 Ezzys 1° and the standard 16 cm in the rear.
But I like the harmonic outline very much. And it is a very good light wind board for me.
Maybe you're interested in this one. Same rocker as the Frugal on the previous pic, but 55.5 and with a funky sci-fi style tail. Very good though.

Hi Ola, is the pink board close to the freegal 80 or would it be more an edition to the freegal 80 in stronger winds for me (65-68 kg)? With 2,5cm or even 2,7cm less in width I would guess it needs quite a bit more wind. And it also has a stronger rocker which makes me thinking it needs some more wind.
As a reminder I sail in Sylt conditions. So no ground swell.
Right now I have a two waveboard quiver. The freegal 80 and an old fanatic quad 2011(highly rockered) in 72 liter which I like.
ps. my biggest sail is 5.2 (works perfectly with the freegal when it is very light (but the freegal works for me with 4.2 also ok/good))

It has more rocker and is narrower and 6-7 liters smaller, so it will for sure feel smaller and require a bit more power. I'd say the difference in power it needs is not night and day through and my guess is that it will not be harder to get going than your Fanatic, since that 2011 version was indeed rather curvy.

But I just remembered that I have a Frugal 66 left too. It's in fact closer to 70 in volume. Production graphics, the black/blue/yellow variant, but build as a proto. That one is a bit less extreme in the rocker and will probably be just perfect as a step down from the Freegal with much of the same feeling.

Hi Ola,
i will use K4 12cm Stubby or MFC 11cm Polyester symmetric frontfins for my Amigu conversion.
As centerfins i can choose between 4 fins from 19 to 16 cm, all with Medium soft flex.
For 5,7 i will use 12cm Stubby fronts and 18 cm K4 Scorcher. But different combinations will get tested too. Boxes will be 13cm Slotbox.
Do you have some special advice for me, thank you.

That is rather big front fins. Then I would stay away from moving the front boxes too far forwards. With 13cm slotboxes you have a lot of tuning, but the problem is that when you move the fin forwards, it inevitably moves away from the rail, and the distance to the rail is in itself an important variable. This is why I stick to 10cm slotboxes for the front boxes. But what I would then advice is to use the back part of the box opening as a reference. I would then place the center of the back part of the opening 30-35mm from the rail and 35mm _behind_ the front screw of the back strap and use 1.5 degrees of toe in.

Best advice I got when getting a tri fin conversion is to try and copy a design you’ve tried and like.
Once you’ve measured it all up and copied onto the old board, it becomes a lot easier.

Not sure we should talk about copying in a board shaping thread. Like the first rule in fight club!!!

That said - As an amateur some time surfboard shaper - i do take a lot of inspiration from other boards i have had acces to.

I don’t think anyone is going to be upset, by anyone upgrading an old board, taking measurements from new boards!
