So... windsurfing can be the most satisfying experience, but also the most frustrating. Why is it that manufacturers can f#@k things up so easily!
I have a new tuttle fin that seems out of spec to the box in the board, or vice verca - the fin base is not deep enough by 4-5mm. I'm after the best way to modify/fix. At the moment I have made up some rubber spacers which sit at the bottom of the box but I keep loosing these when I take the fin out and to be honest they make fitting the fin a bit of a chore.
Thanks for the quick reply sotired. Yes, I understand that regarding deep and standard tuttle, but surely a standard tuttle fin base should fit neatly into a standard tuttle box? In this case the base extends into the box about 4-5mm past the surface of the board, less so at the tail end.
So the best way would be to add material to the sides of the fin base to achieve a proper fit?
ej, grab an aluminum can and cut some strips the depth and semi-circular width of the rounded ends of the tuttle base. This is the part of the fin base that needs to be packed to ensure a flush fitting (not the sides of the base). the aluminum strips will easily sit in the fin box and when you push the fin in they easily mould to the curved shape. Add more strips if need be until fin sits flush.
I have always just added strips of gorilla tape to the tapered sides of the fin head. Seems to hold up for an entire season. Plus makes it easy for me to put it into another board if needed.
Yep Evan, The tuttle has parallel sides so no taper, it is the front and rear edges that control how far it disappears into the box. So you need to either add tape, mono film shims or epoxy filler to tune it perfectly. Unfortunately the tuttle is sensitive to small production tolerances either in the box or the fin head so you often have to tune it to a particular board. Yep, frustrating.
The sides certainly look parallel!
Anyway..thanks all. I know what and how I can fix it now. I just wrongly assumed adding depth to the fin base would be the easiest solution but seems like I was going down the wrong path. Glad I asked here before making any modifications to the fin base.
