It doesn't make sense at all.

Four 17.5 cm fins = 70 cm.

17.5 cm too sort for flexing?

Same drag, less drag, more drag?

Four custom 17.5 cm fins = expensive.

Four tuttle boxes, eight bolts = more weight

Too much to comprehend at the moment.

I owned an old Klepper120 which was an oldskool slalomboard with 3 fins. I remember that at first i always put in all 3 but then one day 1 of them broke and since you can't find that finbox anymore i had to sail twinfin. The first thing i noticed when i went out was that it suddenly tacked and jibed much faster. Then i tried the one fin setting and it went through the curve like a modern freerider.
I guess that with 3 fins or more you increase the sideways resistance of the board making the turn more physical for the sailor however increasing planningtime and eventually speed? I mean, the twinfins where praised because they created a bigger spray and jumped higher. A big spray is made by 1) pure legpower and 2) the board not slipping away over the wave because of that power, ie a slower curve. And big speed = big air so the planning issue and speed issues i noticed could be explained.
So i don't really see the problem in making quadfin formulas though i'd have my doubts considering a quadfin slalomboard.

just my thoughts ...

That brings me to my point:

What is so good about the quad fin then?

Hi All,

The main reason is first because is a Class and we have to play with the rules.

Only one fin, second price, weight but of course will be interest to test to see what's going on.

All the best

Do you think you could handle a quad finned formula board?
Imagine the forces trying to gybe the thing in more than 15k!!
Your ankles would be ripped out of their sockets.

For a formula board you need a deep fin that flexes to allow the fin to bend enough to fly the board. Short fins might proved lateral resistance but the board would sit too flat on the water.
