Trying to keep quiver as minimalistic as possible I am happy with my size spacing's of 4.7 20knt + on 82ltr board, 5.4 and 6.4 (np excess) for 99ltr and 108ltr boards 13knt-20+, open ocean bump and jump.
Looking at getting a recreational race / cammed sail to suit the 108ltr board for flat water sailing in the 15-20knt range.
What size to buy?
Is a 6.4 cam/race going to be much more user friendly/control/more powerfull than freeride no cam?
Would a seven be better?
So many variables with sail types and manufacturers claims. Any advise appreciated.
I'd say it would depend on your weight. Others I sail with we all use different sizes depending on our weight plus ability.
So whats your weight and ability so others can give an opinion.
I would go up to a 7.5 - good for 12 to 20 kts. You should get a greater range from a cammed sail. I weight 75 kgs
No need for cams, the new camless freeride sails from Severne and Ezzy are very good And gybe beautifully - really easy to use. Go 7.5.

I've just brought a big cammed sail for 12 knot winter sessions on the lakes. I use to own a NCX Pro and Code Red. Both 6.5. Decided I only needed one, so got rid of the Code Red. I'm kicking myself now for doing that. I figured I could use the NCX for ocean and lake, but in reality I never used it for the ocean and found it not that good on the lake. Nothing beats a cammed sail for gusty lakes.
Weight, just over 90 kgs
Ability, was almost planing gybes on 121 Starboard Carve, just bought 108 Fanatic Hawk and taken a step back, stalling on the exits, rarely try to gybe the 90 litre carve in chop but was stalling the exits on flat water speed sailing on the w/end just gone.
ab01, not fussed about the lower wind range, got a kite for the lazy option there, would mainly be looking to cover the 15-20knt wind range, sailed a flat water location last w/end with the 6.5 on the 108, fairly overpowered at times so changed down to the 90lrt and struggled in the lulls.
jn1, thinking it may be time to open the wallet/max the credit card, happy to stick with the 4.7 sail/ mast/ boom combo, but get some uniformity and mast specifics sorted with the rest.
MAYBEE
5.0 -6.0 bump jump/freeride 7.0 race
5.2 -6.2..............................7.0
5.5 -6.5...............................7-7.5
I feel like I have just been through this journey. I think if you want to sail open seas no cams i.e. NCX. When you start to go too fast and bouncy you can depower a bit and take the edge of it. Easy to water start etc. On a lake if you don't have your gybes fully worked out (like me) I think a twin cam is the go as quick to rig and good to gybe. A full on race sail is more stable so I don't tend to get pulled around place as much as the draught stays nice and stable. From what I understand the wider the luff tube the greater the wind range. Full race sails go upwind and downwind better but take a bit longer to rig, easier to break bits. You probably wouldn't notice much of a speed difference between a twin cam and a race sail unless you are doing speed runs or trying to get upwind. I think it just a matter of working out what your priorities are. 7.5m is the go. I use a 7.5 all the time for that wind range and I'm about 87kg.

In all fairness, if you scaled your body size down to mine, you would be on my 85L FSW board. If I was on that board, I would have had a harder time than you. I agree with unlocking the wallet, but try to have a go on as many boards as you can. Boards are a personal thing and are dependent on sailing style (Darkplague taught me that !

Totally agree.
For years I used a 6.2 freerace (camless sail) and a 7.8m race sail for my slalom boards. This worked well with my 90kg.
Last season I bought a 7m cammed race sail and I also have an 8m race as well. Since getting the 7m the 6.2 hasn't been out of the bag as the range on the 7 is so good.
I still plan to use the 6.2 for for really bumpy waters.
Since you have the 6.4m, like said above, just add a 7.5-8m cammed sail which is good for 12-20knots.
Pending inspection I can get a 6.7 severne overdrive locally with a 430 mast. Rec mast is 460 and my old fibrespar 430 and 460 should prob be retired. If I get the 6.7 and a new 460 I'm thinking then about getting a 7.5ish race sail that can also be rigged on the 460.
My 6.4 NP Excess is my most used/worn sail ATM and the 6.7 Overdrive would work in most conditions locally on the 108 board saving the 6.4 for use on the 90ltr for B&J locally.
Then when I go to flat water speed location I would have the 6.7 O/D and 7.5ish race sail options.
So much for minimizing things.

S, just to throw another option into the mix, the 2013 7.0 Severne Turbo I recently brought fits on a 430. I was combing the Buy/Sell section a few weeks ago looking for a 6.5 cam sails for 430 masts (I didn't want to own a 460 mast), and saw a cheap clearance 7.0 cammed sail on the buy/sell. I thought 'hmm, does it fit on a 430 ?'. Checked the Severne site. Wow, bugger me it does. Quick phone call to dealer to check that I can convert the cams to RDM. Yep, and the dealer threw in the RDM cams for free. So brought it.
So there are 6.5-7.0m sails you don't need to splash out and buy a 460 mast for. "Less gear, less confusion

Virtually all new 6m-7m sails now rig on 430 mast it is not until you start going above 7m that you start to require a 460 mast

As legless says under 7.0 ,430 no worries, but going with the 6.7 O/D I really would like to have a larger option and 7.5 would be the minimum.
Cripes I've had 10 years out of my second hand Fibrespars that I've made do with on my mid 2000 era sails, I can get a good deal on the 6.7 with a 430 mast included, so only looking at one new mast, 460 to suit 7.5 sail.
