Since the water is very shallow in the bay.. Go with the shorter center fin and 2 side fins.
K4 from UK, THEY ARE COMPOSITE plastic.
You can order the weed fin SUP in USBOX either 21 or 24cm
The FCS Stubbies ..order 10 or 12cm.
Cost in pounds 40 and 22.50, less VAT 9.37
Total for goods 68 UK POUNDS
SHIPPING ABOUT 14 pounds. 68 total
Cost in USD at today's rate just under $90.
Longer fins in ANY box pose a increased threat, since the speed in this is not Mach.9, find something else to fuss over.
These from about 3years back, have a lot more now, including the new stiffer longer wave and Freeride fins.

It makes sense. Even if I don't think that a fin only 10 cm longer could substantially increase the risk of rolling out the fin box, to be on the safe, I'll stick with the current 10 " Dolphin and two side thrusters.
I assume that, performance-wise, it will about the same as a longer fin, in terms of lift and directional stability.
Northern Board Distribution of Sooke, BC, have quoted me about $ 44 freight included, delivered to Montreal, I think they distribute the FCS line in Canada.

according to this ...
http://www.bicsport.com/sup/boards/product/id-116-wind.html
the BIC WindSUP 11'6" DOES have a retractable centreboard
should Ittiandro not try running the board with it down ??
to help him with the issues he describes here and earlier ... |

Dear Joe, BIC make more than one board that fits the description.
What we know is his BIC 11 6 has thrusters. I think a board won't have a daggerboard AND thrusters.
http://www.bicsport.com/sup/boards/product/id-106-wind.html
This comes in several lengths.
Since the OP HASnever mentioned a daggerboard, I assume it has none.
Could be wrong.
These boards from BIC are nice, they are not ultra performers, the build quality is good, the price is low.
I sold these while working for LLBean in a retail store.
OP
If this has a center/ daggerboard, I would engage it only for upwind performance.

the key word there is performance
if one has issues tracking due to waves, current, etc,
i see no reason to NOT try using the daggerboard ...
IF there is one - as you said ... |

I see little point to discuss the aspect in performance in a feature that the BIC probably doesn't have..
The OP has never mentioned one only having questions on the fins, both center and side/ thrusters.
YMMV
And of course you may carry on

Joe
It is general understanding that a full-down centerboard, if it helps in upwind tacking, should be avoided when sailing downwind, as it destabilizes the board. This is also my experience. Perhaps there are intermediate levels , like 1/3 down or so, which can help.
This is why side thrusters can compensate for the short rear fin , by working in synergy with it , enhancing directional stability and lift when the centerboard is up.

This variation (the two short horizontal extensions on the sides of the rear fin , like on an airplane tail) makes lot of sense in term of lift and I wonder if and how this is commercially available.
In fact, somebody has already thought of this. There is a video on the Web ( I can’t remember the address) showing somebody who has fitted a similar contraption underneath the board, in the middle ( like a sort of center board) and he dashes away 2 ft above the water !
I’ve also seen somebody in Montreal 2 years ago , windsurfing with this contraption.
Can you give me some more information on this modified fin, if you have it?
Thanks
Ittiandro |

My iPad is being stubborn with photo upload right now.
I made this fin , series I about 5 years ago. I needed some fins to make one fin for a olde windsurfer when I couldn't find a replacement, I cut and using 2 epoxied 2 to fit the board, left over was the wing part which had similarity to WWII Brotish fighter, SPITFIRE. HOWEVER IT came to me I shaped and fitted the wing part.
Never used, nor still, on a proper board, but did use on my WindSUP,
Unfortunate it started to seperate. I just redid it .
FCS have a similar called 3DS in their box.
I feel it creates lift, but not so much as it's quite small..mine that is.
PS the longboard fin worked great. Will post photos when able.
Version I
All the except more glass and less paint
