epic v8 pro vs v9

looking for a new boat and thinking v8 pro or a v9,  at this point im just doing flat water. i currently own a v8, gen 2 v10 and a v10l. my question is will the v9 be faster on flat water?(they say it is) on paper it should be because its a inch narrower and the same length but it has way more rocker and i think that will slow it down. also which of those boats have the smallest cockpit?

I recently had a couple of paddles on a V9 (the only one in South Africa!) and absolutely loved it.  But...  all the paddles were downwind and I didn't get the chance to paddle it on flat water.

The cockpit was definitely a narrower, more comfortable fit than the V10S, can't comment on the V8Pro.

Sorry - this is almost entirely irrelevant given the specifics of your question!  For me though, given the choice of V8Pro, V10S and V9, I'd go for the V9 every time.  If the V10 3g was added to the mix, I'd go V10 3g (which I paddled in Aus, also downwind, 2 years ago). 

I've paddled the V8pro in various conditions and I own a V9. I haven't done any back to back speed testing but I think they would be similar in flat water speed. The V9 is probably a tiny bit faster.
The V8 pro is not great in downwind conditions whereas the V9 is one of the best downwind skis (in the stable intermediate category) that I've ever paddled. If as you say you're just doing flat water; you won't experience anything like the full potential of the V9. The V8 pro is a nice ski if you don't plan on surfing. I think it has a better speed to stability ratio than the V9. 
I found the cockpits to be similar. Neither of them are what I would call snug and they're not as comfortable (for me at least) as the cockpit in the V10L and the Carbonology Sport Boost LV.
Your choice will depend on your motivation for buying another ski particularly since you already have a V10L which is a fast ski optimised for the conditions you paddle in.

Seems like you already have a pretty solid fleet of boats. I switched out my v8pro for a v10g3. It's a significant difference (for me). The v8pro is rock solid in any conditions and the perfect "first ski". Your v8 should be a great intro boat for teaching new paddlers or paddling in cold/really rough weather. The v10g2 and v10l are both great flat water boats if speed is your thing. I think the v8pro or v9 would be kind of redundant in your fleet. If your really only paddle flat  water either the v8pro or v9 would be fine, but if you ever get into downwind the v9 or v10(g3) would be better just because they have more rocker.

Another consideration if you aren't tied to the Epic brand would be the Vega flex. Seems like a lot of ski for the money and is awesome if you downwind. 

Hi Atlas, I'm interested in your opinion on the V9 compared to the Boost LV which I currently paddle. I find the Boost LV to be super stable & comfortable but perhaps a little too wide in the cockpit (41cm) and could do with more volume in the nose. The low volume makes for a wet ride but on a positive note is super easy to remount. I'm 80 kgs with full hydration pack, PFD & leash.

Just found your thread which pretty much answered my question. Seems like the Boost LVX might be the better option due to the more compact & comfortable cock pit (over the V9).

BTW, which 2 DK rudders do you use on the LV?

Thanks in advance.

Hi Possum.
Overall I found the V9 to be the better pure downwind ski but the Boost LV X (which is still very good downwind) is more comfortable and versatile. As such I sold the V9 and kept the Boost LV X.
Both the V9 and the Boost LV X have a similar overall stability but the V9 seems to have more primary stability and a little less secondary stability. The Boost LV X has a slightly wider and more rounded hull and thus less primary but a little more secondary stability. I find this profile to work better for me particularly in crappy side-on conditions which I encounter frequently. The low profile bow of the Boost LV X seems to catch less cross wind than the V9 too (although the V9 is not terrible in that department). Not surprisingly the V9 doesn't nose dive as much as the Boost LV X. It also drains quicker. I removed the kooky one way valves from my Boost LV X. Optimal drainage is more important to me than dry balls on the rare occasion that I'm sitting around in the ski not actually paddling. I always use a wave deflector too. I found the V9 didn't really need one.
There's not much in it. Most paddlers would get confident in either ski. Large framed or overweight paddlers in particular will really enjoy the V9… Or the standard Boost X.
I use a DK 7" 30º high chord rudder most of the time. This rudder is nearly weed free (it still catches a bit of fine weed like sea grass) and is responsive enough in most conditions. For really rough or big downwind conditions I use a DK 9" 20º high chord rudder. This rudder provides sensational directional stability and very responsive steering but is overkill for most conditions as it's a bit of a weed magnet. The rudder placement on the Boost LV X is 100mm forward compared to the original Boost LV. This makes a big difference even without fancy custom made rudders.
Most of my comments about the Boost LV X apply to the Boost LV except the characteristics relating to rudder position.
Hope that helps.
