View Full Version : Fin for KidsPro S-Type as Speed Board?

19th April 2007, 10:57 AM
I am thinking of using a KidsPro S-Type as Speed Board as I hear there are few people using them at Sandy Point. My question is what type, size and maybe brand fin should I be looking at for a 5m & 5.8m RS6 sails. I am about 82kgs and 6'2".

I am only 74 Kgs and 5'10" and I found assymetrical speed fins between 19cm and 22cm worked very well for me. For your size I would think the 22 -24 range would be the go in Assys and 25-28 in Symmetrical. One thing I did find is that the board was smoother and more stable with a raked fin or a normal raked TM45 20cm fin set further back on the box. Because the board is quite short you will need to be well powered up to get going but this board has huge potential on good flat speed water, more than I have tapped so far at over 42 knots. TM45 22 or C3 raked would be good, Techtonics 26-28 in symmetrical slalom type. The footstrap stance is closer than conventional adult slalom boards but I actually think this an advantage. The strap positions are also a bit closer to the rail for big feet but I also like this and just run the straps a bit bigger with my feet further in.
Hope this helps

Opps. Sorry. I misread the post and in my reply I was referring to the Pro Kids Sonic. The PK S-type I had was a very nice fun med to high wind slalom board but not really one I would recommend as a 'Speed' board. I never managed much over high 30's on it, it just got too flighty. Smaller boards were a lot easier to keep on the water for me. I upgraded to the PK Sonic in 06 and this was indeed a 'Speed' board for me with many 40+ knots sessions. Now I am on a IS50 and feel that it is more stable at top speed in the chop and a little easier to get going but the PK Sonic still has huge potential in good conditions.

Isn't the pro kid Sonic 06 the same board they've named iSonic 50 in 2007 with minor changes?
I mean, looking at the "mere numbers" it seam so..

The ProKids Sonic 06 and the iSonic50 '07 are very different boards even though some of the measurements are in the same ballpark. Both are very fast though!

Did they change the rockerline by much?
