View Full Version : iSonic 127 - Best possible speed?
22nd August 2012, 03:38 PM
I ride an iSonic 127 Carbon in sea but not in open sea. The area is sourounded by islands. Mostly in choppy water with Gaastra Vapor 7.6, 2009, and with SelectS 10, 47 or 51 cm.
I have found it hard to get over 24 knots in 6-9 m/s in reach or light downwind. The rig is set ok. What do You suggest to get faster? Anouther fin, perhaps?

I have only tested my speed once, going 29 knots on the following setup:
Isonic 127 Carbon, 2011
Tectonic Talon 50 fin
North Warp F2011 9,3
Open water but surroundet by islands so only small chop.
Speed was recordet on a Garmin Forerunner 910XT
My guess is that your fins are a bit too big for a 7,6.

To be honest 24k peaks is a bit on the slow side in 11k to 18k (6-9ms) winds. In 18k gusts on small chop you should be hitting high 20k's to low 30k's pretty easily on the correct size sail. 9m-ish would be the normal size in these winds.
Your S10 47cm is able to go fast. I recently had a 34.9k with an 8.6m on flatish water, so I know for sure it can move.
I think your 7.6m might be to small for the iS127. These boards really really like to be powered to over powered to get high speeds and comfortable.
I guess your fins are fine, but you need more juice, have you got a bigger sail? How heavy are you?

ThankYou for quick answers!
My weight is 77 kg. I have a set-up with the boom up to my chin and the mastfoot back. I try to sail aggressiv with a lot of pressure through chops
I also have an TR 4, 9.2, that I normally use on th JP SLW. I will try it next time on 127.
Interesting with the remark on the S 10-fins. I suppose I will keep them as I now know they can be as that fast.

Going fast is no easy thing. Lots of people do go very fast, but it takes the right board, sail, fin, wind, water state, venue, skill. I weight the same as you, but have a iS 111 with a 42 Tetonics Tomcat fin. With a 7.6 race sail, I have hit 31 knots on my GPS twice, but I can't seem to go any faster. I have been carrying a GPS for the last 8 years on every outing.
I am not heavy, my sailing site only allows an occasional run into flat water with good wind and the board & fin are too large for really fast speeds (35-40 knots). I have the skill (28 yrs windsurfing), but have hit a wall with my set up.
Your 7.6 may be a little small for your board, but given your weight, I don't think you will do any better with the 9.2. An 8.5 may be what you need.
Good luck, it's fun to chase personal speed records.

Just picked up a 2011 127 this morning! Can't wait to use it!

Thanks Ken! I think You are right. All conditions must be perfect to hit Your own record. Alllthough its fun to have the GPS. You allways have the possibility to get new record anyway (alpha, NM, 100, 250, 500 and 1000 m). I think You are right that 8.5 would be a good size with my weight.
MackaPacka - I hope Yo get wind today!

You should be able to get to well over 30kts on an Isonic 127 - I have Mistral Slalom 123 (similar size): in Portland Harbour with an 8.0m F10 North WARP I can get 32 kts with a 43cm Select S11 or 28kts with a 9.0 F10 North WARP and 47cm Select S11. Just been on holiday to Bay of Rosas in Spain, I managed to get 32kts in big chop with a 7.0 North RAM and 40cm Drake fin - at this speed the fin was maxed out
Strangely one day it really blew and I was easily getting 33 - 34kts on my Fanatic Falcon 90 with the 7.0m sail, when the wind increased, even though I was not over powered, my speed dropped off to 29 - 30 kts - I suspect that in slightly lower wind I was able to find a smoother line through the swell, when the wind increased I was unable to sail as smoothly, even thought it felt far quicker
