View Full Version : hwr mast track possition

hi...witch possition is the best to put the mast track in different wind speed and sail sizes...!!i use severne reflex1 12m2 and reflex2 11m2!!

Costazzz, it depends a little bit on what fin you have. The best performance upwind/downwind on the HWR is when you get nose lifting as much as possible; you can do this with a really powerful lifting fin, or by running the mast track as far back as possible. I am normally running my track so far at the back the plate covers the serial number, then just moving it forward as the wind increases to have better control.
If you have a powerful fin already and with the track all the way back the board feels a little bit 'sluggish' (like it's getting stuck on the swells) then try the track halfway between the back and middle ;-)

i have a hurrice frb7 and i use it as an all around fin!i felt all ready this think that you said (like it's getting stuck on the swells) thats why i do this question! I felt that with my 12m2 sail in 14 knots!!the problem is that the wind speed at the location that i use to windsurfing is never the same with a lot of gasts so i am trying to find the different positions in different winds speed and sizes of sails!!it is a bit crazy and i fill like never will be correct in my choise!!when you change the sail from 11m2 too 12 the theory sais tha i must put the mast track a bit frond from the position of 11m2.!!what you think......?????

"Getting stuck on the swells" - is this happening when you go across the waves on one tack or when you go straight in to them (depending on the wind direction I guess). It's fairly common on this board to get the sensation of being a little stuck on the swells as you go across them; I would keep the mast track all the way in the back on both the 11 and the 12 to combat this and get the nose lifting.
I don't know too much about the FRB7 fin from Otmar but I assume it's pretty powerful? What rake do you have the fin at?
26th October 2011, 04:53 PM
the rake of frb7 is 4.5 degree....i am trying to be used of sailing about 3cm back from the middle of the mast track!!that means that the plate of the base(base of the rig) is covering the beggining of the mast track!!

thank you very much for your time Sean....

OK, that rake sounds good. I was thinking that if you had it much more vertical (around 3 degrees), that can push the nose of the board down quite a bit. Once you get used to having the track that far back I think you will like it ... let me know how it goes ;-)

Hi Sean... i start to be used on putting the mast track all the way back and i have so match more power!!i am smiling...thank you very much!!the board is just great..fast with controle with both sails 11m2 and 12m2...!!i would like to ask some things about reflex system of severne sails...can you help me with this or to inform me how can i get answers to my questions....??
Thank you very much for everything!!!

Good to hear costazzz!
Unfortunately I can't be too much help on the Reflex system as I've never tried the Severne sails... Remi or Steve should catch this post soon and he can give you all you need to know ;-)
If nobody does, I would start a new thread with your questions on this forum.

thank you so much...your answers make me really happy!!i wish for some answers about reflex.....!!

What is a powerfull vin for the hwr. I have a virus 73/70 but it feels to small to point. Sailing maui tr 7
13th March 2012, 07:26 PM
I don t know if you read this, but the rake of my virus 72 is 0. Problem is upwind. Can you give me a kind of solution to get better pointing? Is a 4 degree rake better pointing? I sail a hwr
Like to hear

You could try tipping the fin back 4 deg. (not much at all).
Tighten the rear fin screw until you get the 4 deg. rake (measure it with a
protractor) then snug the front screw and take it for a sail.
This will tell you if your upwind issue is the fin rake......or...

Thanks may be an other question for you if you are willing:
Do you mean rake at the back of the fin or the so called leading(front)edge. On the back it is zero.
But I will try that trick and see what will happen. Do you have experience with the fin for a HWR?
15th March 2012, 03:01 AM
No, I don't sail/race formula anymore, but I know that a few years back all the formula racers were
tipping the fin in the box a few degrees on an experimental basis, then as soon as they determined the
optimum angle, they added material in the appropriate spots on the fin root and refit the fin to the
box in the optimum orientation.
If your fin has zero rake on the trailing edge (many formula fins are designed this way so the flow over the foil is normal to the trailing edge) then you can use the trailing edge to measure the leading edge
Most top of the line formula fin designers have already done the research to optimize the leading edge angle, but perhaps not on all the different boards.
If Remi, Sean, and the Starboard Formula team suggest a particular fin for your HWR (do a search on
HWR and you should find quite a few fin recommendations) it might be good to get one and try it compared to the fin you are using and see if it solves any of your issues.
Sailing fast upwind on a formula board requires several very "non-intuitive" techniques.
Railing the board slightly to leeward to go upwind is very non-intuitive, but if you watch the worlds best
formula racers, they all do this to some degree.
Flatter is faster in slalom, but slalom does not require the extreme upwind/downwind sailing angles that are the norm in formula racing.
Hope this helps,
