The only difference between a DeepTuttle fin cavity and Std. Tuttle fin cavity is the depth of the cavity. The dimensions of all the angles and widths are the same and the std. Tuttle fin should fit into your board very nicely (with perhaps a wee bit of "fitting", but it should go in with the top of the fin root just proud of the bottom of your board.
The difference in depth is 0.709" or 18.0 mm.
So, in order to use the shorter based std. Tuttle fin in your Carve 145, you need to buy
2 ea. 6mm x 1.0mm pitch pan head screws that are 18-20 mm longer than your std. screws.
According to the Starboard screw chart, the 2005 Carve 145 uses the following:
Carve 145 M6x60+65 = 2
Carve 145 (H.D.E) M6x60+65 = 2
So, you need one 78 mm long screw and one 83 mm long screw to install the std. Tuttle root in in your board.
2 80 mm screws may do it, or one 75 mm and one 85 mm.
You can always cut them off a bit if it looks like they are "bottoming out"
beyond the brass barrel nuts in your new fin.
Hope this helps,
