I install the box further forward in the board. (normally a box is about 80mm from the back of the board, I put mine 90mm to 100mm from back of board).
Then when I box a weed fin I set it to the front of the base. When I box a more upright fin I set it further back in the base.
That way I don't have to have the leading or trailing edges outside the base.
Hi Rasmus,
a profile with the thickest point further forward does not significantly move the COE forward. it will still be very close to 25% from the leading edge with most "normal" sections.
moving the straps and mast foot back helps a bit, but on larger weed fins there is not really any other solution than moving the fin forward either on the base or moving the whole box. on larger slalom boards it might even be worth installing a second box in front of the old one and use a plug to cover the box that is not used.

Great looking video as always, good to see you were able to get out and test a creation at last, you looked happy with it.
lol I thought it was funny at first then i looked at the sail ;-( not what i needed
If i don't put the music over it U can hear them snaP!!
r well was a fun day !
I was thinking i could of put my 7.5 up n jumped on the CA44 would you guys say
that a 22 weedie would hold ?
so exited i get my DRAKE back from the reboxer this week time to START the
ITCHING!!
re boxed a couple of slalom fins, took a mould of the slingshot both sides at an angle between the slingshot and 45deg, the grey fin has notched up 32nts in 15to 20 on a 5/8 n/p rs, the black fin is an old us box slalom 33 laminated with 4 layers of 2oz carbon and 2 layers of 3oz satin weave and polyester resin hopeing the angle is ok for weed
NICE ONE KEEF !! THEY LOOK THE GOODS CANT WAIT TO CATCH UP !!
CANT BELIVE I MISSED YA THE OTHER DAY U SHOULD OF SAID U WERE THINKING OF COMING UP ... NEXT TIME PM ME OR CALL 0403902721
Does anyone know if you can buy G10 material in a sheet around 16mm thick
And what grade is suitable for fins?
Thanx
I spent today epoxy / glassing a tuttle box into a broken slot box Speed Slolom Board. Ready for when I rebox some old fins, I picked up some moulding silicon ready for the job. Will post up the reboxed weed fin when I get it done.
While I getting out some glass out of storage I found an old Invoice
1 Lineal Meter Unidirectional Carbon cloth $13.15 Oct 1989 what do you pay now?
I was putting carbon fibre in my fins back then
keef, I thought g10 was fibreglass laminated with epoxy, then put under 10 tons of pressure (I guess that's per square inch) to maximise fibre to resin content.
That's why the stuff is so strong and tough, with no voids.
It's the preference here as it doesn't wear as fast in our gritty weed.
Finally got round to taking a photo of my 2 weed fin's cira 1989 they are both up for reboxing to tuttle & will report in when I try them. The white'ish one is quite thin about 7.5/8 mm Raked at 25 deg then, 40.5 deg, 255 deep. The black one is 12/13 m thick. That one I made for a race board for extra lift when beating up wind. I also moulded it, layed up the glass & carbon on both sides poured expanding urathane foam in the center (to reduce weight) & clamped the 2 halves together. Start rake 34deg then standing up to 43deg 275 deep
unfortunately chocco we have to sail were there is weed to get flat water there are very few spots that hold good speeds in NSW so the search is on for the fastest weed fin
THE NEW ONE SAILED IT YESTERDAY GOT A **** LOAD OF LIFT FROM IT !
I even put my mast track forward 3 inch !! just to flatten it down wen i did this it felt and "apparently" looked real good i was also able to close the gap more comfortably and felt solid upwind and down for a 21 cm, I'm sure i will be able to sail the 7.5m on it as it was so solid with the 6.7m and Ca44
happy camper come on wind !! good fit too decrepid .. on to the next one let the itching begin ..wife not happy
