I'm after a bigger fin for my Fox 140, I'm thinking something in the 48-52cm range and more of a powerful race fin than a Freeride fin for those light wind days with the 8.6. I can find and have some nice Tuttle box ones but nothing in power box.
Any ideas? If I can get them in Canada even better.
last resort is taking a file to one of my tuttles and converting it, should work as far as width is concerned but the powerbox is slightly longer so there would be a gap at the front and back, not sure that would matter to much?
The gap would be 2.5 to 3mm each end at board level tapering down about 5mm . I wouldn't think it would effect much . However filing a tuttle down to a PB would be a epic journey . Ive done these mods before but i used a milling machine to get the angles perfect . Ive converted two formula fins to halfway between freeride and pointer to 50 and 53 cm . Both work great and make plenty of lift . Both these fins are way better than a JP freeride 52 for planing in light winds . I believe JP make a PB supersport 52 but are rare secondhand or very expensive new . Doing the box change by hand could be done , but its probably going to turn ugly . Select might make one.
Have you checked out Makani fins? I usually use their weedies but they have pointers as well.
I've been really happy with their weedies - spin out resistant and point well enough for me.
I tried to paste a link but it won't work..??

Miles from Canada but WSP has 50cm JP SUPERSPORT in G10 powerbox $80 bargain.
Could be worth getting a post quote , the world is not that big anymore

Once getting as big as he wants, and a performance race fin I think he needs carbon and Makani don't do one.....??? Not 100% on that though
Carbon fins bend just us much as G10 but if you hold the tip of a carbon fin and twist it,there is much less twist than a G10 fin.
How does this help? Not sure,just passing on what i have heard.
hmm PB 48 cm slalom fin ...
not sure i have seen one
is freerace close enough ??

Tribal Powermax, while not a slalom fin, comes in 48cm and powerbox. Slowboats fins work.

Carbon is clearly stiffer - fact. So unless you are talking about the fins that have just one layer of carbon in the middle for looks, no, G10 and carbon fins are not the same.
Carbon is way lighter for the same thickness, so no, carbon and G10 are not the same.
G10 is more durable (resistant to abrasion). If planning on hitting bottom it may be a better choice.
Now, if you want a fin that has a certain bend, you can acheive that same bend with carbon and G10 (and even steel or aluminium or playdough if you wish) but the thicknesses will be wildly different. Once you get to a certain length, G10 and fibreglass are simply too bendy for a high performance fin. Thus people use carbon.
I am no racer but once you get to around 50cm the difference in carbon vs G10 is a lot.
The assertion that a carbon fin bends just the same but has more twist is ridiculous. Different foil shapes will do that, but carbon cannot be the same stiffness in direction X and bendier in direction Y
Stop listening to the friend who told you that stuff.

3 emails over the last few weeks and so far no response from them!
WSP? Guessing that's a shop somewhere?
I would think if carbon was layered up the same as G10 it would be the same weight , a lot stiffer but weaker in snap strength ???
How this relates to fin construction , I'm still working on.
What I've seen is carbon fins use a sand witch kind of construction . ( either a soft light foam or non structural hard core ) .
G10 is solid so it's hard to compare.
I have a Curtis carbon fin that is sooo light it has to be hollow.

The seas frozen from January to march so I would have 3 months to do it (-;

Those are currently on sale $143.99 USD for the 49, and $151.99 USD for the 52, go to their website.
I'm not affiliated with them but a big fan of their fins, I don't do racing or slalom though, mostly wave and weedy wave stuff.

Makani don't seem to want to answer my emails so giving up on them.
Really like the look of the Drake Slalom sr6b 50cm but having no luck finding one anywhere.
There seems to be one thing in common for all windsurfing brands, and that is inability to answer emails.

I was going to give it another but their website is not working for me at the moment, if you have an email for them could you pass it on to me. Maybe I've been using the wrong one.

i sent one and got an answer already

Ok sending email now, thanks.
That's the magic email address! Although telling me to order it online doesn't help much as all I get is this
