Hi Dave,
The boards in the shot are the 20' 16' 14' & 12'6
We were trying a few weird fins in the river tonight, the 12'6 x 27 with the weird fin is about as fast as the 14' x 26" board its on top of.
I need to try the 12'6 against some production board a 12' Glide or Starboard Pin or the like, to see where we are in terms of board speed.
I am about to glass a 12'6 x 25" displacement board, going narrower I want to try & stabilise these boards with that "weird" fin, it dampens the roll a tad.
If your down this way come for a paddle with us!
Cheers
Dean

hi, got a question for you. a well know shaper of many craft( not dc) reckons a fin right back will lift the nose on a board, where as i fin pushed forward will lower the nose rocker, but is harder to keep straight (this when under paddling). before i heard this i found a normal surfing sup paddles like a dog with the fin back. any thoughts
cheers

I think I need more info about what you are saying here.
Can you please post a pic of the "normal surfing sup" that paddles like a dog with the fin back? Also I would like to see the lenght of fin box as well thanks.
How far has "a well known shaper of many craft" moved the fins?
What size were they? Were they as exagerated as that "weird fin" on my 12'6?
(I go to extremes so there can be no mistake in feed back)
What size board/s are you testing?
I can only pass on what I have found from experience in testing the boards & fins I have.....that 12'6 was keeping up with the 20' over a short 100m sprint.....if what your saying is true, wouldnt the 12'6 be an absolute dog with a fin that far back?
According to the "well known shaper of many craft".....wouldn't I have to be hanging 10 while paddling that 12'6 to keep the nose down with a fin that far back!

Check it out......how far back do I need to hang it before it becomes a dog?


This is the outline of the 12'6...it has the tail of my wave board below so it is a "normal sup" in that regard.

the dc 8'10 i found hard to paddle with the fin back in a 10" box with say an 7' fin. this what i have found. he is saying the board sits a little different with fin positions. i'm not standing anywhere different, so the hang 10 thing is a bit over the top. maybe the flatwater boards with their little or no rocker it might not make much difference. have you tried the fins forward? trevis has won d/w races on 12'6 boards with 7" inch fin slid right up the box as far as he can get it. he happens to be one of the best paddlers in oz.so i figure there must be something too it. anyway i guess you have given me your thoughts

interesting debate although i do recall at the malfunction race travis's fin screw hole bit broke and his fin slid to the back of the box and then pivoted back on the pivot pin for a majority of the race. he still managed to beat home california Kyle to the shore

The testing I am doing is on flat water only, its the starting point to making more accurate assesment. When you start adding variables it becomes too hit & miss when comparing hardware.
At this point I am looking at board speed powered by man only......no wind or waves.
Then I will adapt what is learnt to other types/uses of boards as relavent.

Hey Dean.. Out of those four different fins which one do you think works best?

I'm guessing the dolphin fin shaped fin..

I am trying to get my head around the red one. Is that a removable fin or is it actually glassed into the board?

Are these all fins you made yourself or can you actually buy these shapes somewhere?
