Putting the Quads on negates the tail width, no stringer fin to cause drag. rail to rail becomes just that.

It sure as hell worked a treat. Had the 6'8 out in head and a half this afternoon.

Are you covering over the single fin slot while riding as a quad or just leaving it? Wonder if you'd notice the drag?

Just left it. Might get around to doing something: fill it with silicon?

If you've got access to a 3D Printer......Thingiverse has some downloads for fin box covers. As well as fins and whole surfboards.

From another forum:

"With many boards coming with 5-4-3- fin options I've often thought about empty fin plugs / boxes and how they might disturb the flow of water across the most important part of the board, the tail.
(particularly the Future fin boxes. I surf my Dominator as a thruster most of the time so i have two vacant fin slots.)

I've used a hose to create a fast flow of water across the bottom of my board and have seen the disturbance to this flow when the water enters and exits the empty fin slots at speed.
The water will enter and exit at 90 degrees to the bottom of the board at certain flow speeds.
I am guessing that this disturbed water flow would be increased by a board traveling at speed across a wave face.
And that it could react in different ways at different speeds as the board manouvers thus creating random drag, and lift.

I'm thinking of cutting down an old set of fins to create an insert for the box that will finish flush with the bottom of the board.

Should i stop loosing sleep over this???
To be honest, with my standard of surfing and my age (60) this will never be a real problem for me.

I'd be interested in your thoughts"

Bet there are plenty of broken fins to choose from in Bali.

well he could just go to a nearby surf shop and buy Futures' fin box inserts

or possibly just stop surfing altogether

I was thinking Nick could go either way on this one.

But he went both.

Just stick gaffer tape over the top.

I've often thought similar things about those people the use wingnuts or similar adjustable bolts on their longboard fins....

They go to all the fuss of paying top dollar for a fancy 10" volan fin and then go and stick a massive chuck of metal either in front or behind it....

I'm coming to conclusion that most of all this shit is marketing and we should all just forget about it and just go surfing.

It will make such little impact if he surfs a Dominator. What a tool that man is.

heres my actual tip! Don't do a five fin set up at all. Minimise the impact of boxes/plugs on your board's tail flexibility. Futures esp, they're a great system but you stick five of those boxes next to each other across 18" of the tail block and good night feel.
