My 8.4 TR8 rigs on a 460.

Needs 28cm of extension, so you need a decent extension to go with it.

Many of the current model 7.8 to 8's will rig on a 460. It's not a huge jump to a 8.4m. So if you get a grunty 8m sail that could solve your problem.

You also need to be sure that it will fit your boom size, not just the mast

ahaha

Got the board (135 SP), the wishbone, 44 and 48 fins, just missing the sail...

Hi Sean,

I have a NP H2 8.2 that rigs very well on my NP 460 SDM. Also have 2 older NP V8's (7.5 & 6.5) that also rig on the 460 so am very lucky. Their 8.7 H2 does not rig on the 460 though.

Cheers.

I'm more after a freerace sail for very light wind,
having a 7.8 rs slalom I would like a decent gap to the next sail, 8.5 would be fine.

or....just use a 460 mast and lots of extension!
I use 460 + big extension with old NP V8 streetracer which says use a 490 mast. I've never had a problem.
I own other sails that list an ideal mast and then an alternative mast
(6.6 on with either 460 ideal or 430, also with 4.7 wave sail (adj head) 400 ideal or 430, so thats one going up in size and one down.

Thanks for all the good advice guys.

I have found a cheap 4.90 mast so I might be able to go bigger than 8.5.

never heard of the brand though : Viper, model : xselerator 100%

Anyone knows it ? And is the curve good for a Pryde (H2) ?

Cheers

Sean

Yeah, its an old North Sails mast, 100% carbon. Good masts. Now you can go to a 9m, that's a much better gap from 7.8m:)

Hey Sean, as the other guys have said the jump between 7.8 and 8.4 isnt huge. You should match the sail to mast carefully and the recommended extension otherwise you will be sacrificing something like early planing or top end control, I understand the bigger the sail the more important that this is. If you do want to use other brands of masts with your sails Peterman has a bit of list of masts he has tested which provides some insight on imcs stiffness and bend curve measurements. His other pages explain more about mast measurements.

I had a 8.4 m for many years but for my weight it was just a tad too big for me for nice sailing in choppy bay conditions, so have just changed back to a 7.8 and for me the usability and top end control is gold
