Twin keel fish angles.

[gutterball]

I bought a modernised twin keel fish last year and it took me a while to get used to.
I then started to get used to the board, and how to turn the thing.

However i loved this board in the right waves (waves fishes are intended but it could handle a bit more size- like up to a mellowish 8 feet-> you know what i mean)

The fins are long twin keels and were put on very parallel.

My board got smashed one day and i ripped off the fins, took it to a glasser to repair, who placed the fins on more of an angle (without me telling him to).

The fins seem to not only have more of a angle towards the stringer, but also have a slight X-wing type angle - i mean if the boards laying down, the fins are not vertically up like before, they are a bit off on an angle.

I took the board for my first surf today after the repair and i got to tell you, the waves were a bit too punchy for a fish but the board was going so much faster through bottom turns, turned sharper too.

Im just wondering about if this board, as i got used to it before , it seemed best for pumping speed down the line in semi fat pointbreaks between 3-6 foot.
But my surfing was really inconsistant.
Like even in the right waves, it sometimes took me a few waves to get used to my board , before i was surfing ok.

Just basically wondering if the fins were placed wrong in the first place or designed for a different type of surfing/waves than what the fins have been placed on like now.

Im also wondering if the fin placement of the fins now, will make the board less ideal for my favourite down the line pointbreaks.

Hi and welcome to the forum.

Fin placement on a modernised twin keel fish. Interesting question. Tow in and fin cant which are the two things your refering to will as you've experienced effect the way the board behaves.
For this type of board i would say that there is no right or wrong way to put them on. Staight, parrallel fins will generate less drive from a turn but the board will go faster and make flatter sections of waves and are hence better for less steep waves. Adding tow in will help get more drive from harder truns to a degree but will slow the board down a bit whilst the fin cant will add some lift to the nose, helpful in steeper waves.
Having tried both set-ups you should be well placed to say which you personally think is best for which waves and i for one would be very interested to hear what you find.
The really important thing though is to get the fin size right for the rider. Base length and height for the intended rider as these types of fins don't generate anywhere near the same sort of thrust as you'd get from a modern 3 fin thruster set-up.
My gut feeling though is that what you have now will probably be a better comprimise.
