View Full Version : Deep Tuttle dimensions?

28th April 2009, 01:10 AM
Hi Roger, I'm traying to make my own wood board, so I need interior dimensions of the Deep Tuttle (or ext. dimensions of a standard head's D.T. fin), can you help me? I don't found such information on fin manufacturer's sites. I also made a .jpg file following measures you put on a thread, but I'm not shure wether is it correct, I'm sending it as attach.

Romas, thanks, but in a previous thread Roger said this drawing is bad.

Hi Quequen,
I've conmpared your drawing and dimensions with the originals I have, and there are a few differences.
Change the 105.15 dim. to 105.038.
Change 18.05 dim. to 18.388 and 13.05 dim. to 12.47
The height is slightly different as well.
Your 68.54 should be 67.480, and your 50.35 should be 51.768 measured on the 80 deg. angle.
Make these changes and you should be very close.
Of course, some fitting is always going to be required.
On the Polish Skoter dwg. I did not say it's bad, it's just a little different from the
originals I have.
Anytime you have to measure things on angles, generous tolerancing seems to come into play.
When you want two angular and two flat surfaces to fit really close.... fitting them is the only way unless you have high production items with very finite process controls.
Hope this helps,

Maybe the most sensible thing for the finbox is to buy an industrial design from for example Chinook (see http://www.chinooksailing.com/products/product_info.php?cPath=64&products_id=167).

And use an industrial box for the mastfoot as well...

Roger, thanks, very complete data! I drawed it again, still remains a little difference on the large, anyway far enought precision for me!.
New file attached.

PG, I didn't know that, I should start from there! anyway, chinook, thailand and 1rst world as a whole are far away from my city. I'm looking for a way to purchase from here. Thankyou.

Hi quequen,
Where are you located?
PG is correct!
Much easier to buy a replacement fin box, with all the dimensions already cast into it
(and the mast box as well) and then simply make the proper size cavities, glue the box in with a slurry of thickened epoxy, and glass it to the top and bottom skins of your board.
You should be able to import a deep Tuttle fin box from Chinook, or various other board
repair parts dealers.
If you have a local dealer, they should be able to order you a fin box.
Also check if there's any sort of board repair shop.
They may have one in stock or can get you one for a good price fairly quickly.
