Here is another look at the Dagger fin and the Thresher in the board. The Ninja SOLD out as soon as I finished them, will make more to complete some backorders. NOTE: You can use 2 Dagger fins in smooth flat water conditions.
This Dagger fin is used up front to help your board plane easily by giving lateral support in the power paddle area, helping you from over working yourself to keep your board traveling straight in strong side currents.

Hey Larry,
Now I see what you mean by using the Dagger fin “up front”.
Looks like it is positioned in front of where you stand on an SUP. I imagine it creates a lot of stability in the area between the fins.
Here is a 12 ft. SUP with the Dagger Box I installed for a fellow Swaylockian as I promised. Hope to get a ride report back.
The big yellow Ron House that Larry used as the example in the photos above is mine. Picked up the board yesterday and took it out in the water this morning.
I had the dagger fin in the front, but did not have one of the threshers in the back. Instead, I was running a standard 9.5" fin similar to a “California Classic.”
The addition of the dagger fin just forward of where you stand makes a significant difference in keeping the board tracking in a straight line, which means you don’t have to switch sides paddling as often and paddling efficiency is increased. Usually, I am switching sides every 2-4 strokes, but with the dagger fin installed, that number was increased to 8-10 strokes and that is taking into account that this morning there was some new swell in the water and the high tide backwash (it was a 7 ft tide this morning) was bringing bumps to deal with from both sides.
It’s a nice low tech alternative to having a tiller installed on your stand up for those distance paddles.

Thanks feralseppo for the review. Looking forward to hear how the Thresher fin for the rear works over a regular surfboard plan shape, with the Dagger combo.
I also found another interesting problem that has been happening with the SUP boards. They are all using standard fin boxes which are two piece. The problem with this is that SUP boards are and have been more than not beaching. Hitting the fins, causing the bottom of the fin box to crack. This can happen and you may not even know that your fin caused the bottom of your box to split until your board starts to take on water which then is a pretty expensive repair and damage to your EPS core.
So I am bring back our Hi-Wind Box that I designed in late eights for Windsurfers, which is a ONE PIECE FIN BOX also with the special heat treated coating like ProBoxes for superior bonding installs like the pic below.
that dagger model looks a bit like an old school “d” fin! Is it similar or totally different?
Would ik work on a classic longboard or would the hole in the middle disrupt the working as a “surfing” fin?
Hi surfer_dave, Glade to see you like the fins thanks, am working on 2 more rear fins and another Dagger fin for flatter rocker boards.
The Dagger fin is completely different than the “D” fin. The Dagger fin posted here is 5 1/2" tall with approx. 10" base. The “D” fin is over 10" tall with alittle under 10" in the base. The rakes on both of these fins are different also, The Dagger fin has more rake to cut thru Kelp with less drag. The “D” fin is more of a Pivot shape for turning and has alot more drag.
The Dagger fin would be a nice fin on a Longboard with little tail rocker, placed all the way forward in the center box.
The type of hole in size and location of these SUP fins have no effect in performance feel at all, like other properly placed holes or slots would have.
Thanks for the call today. The fins look great! I think the dagger fin is going to work perfect for me. I can’t wait to try it! It looks as though I’m going to end up having to put them on all my SUP’s.
