Checking every option is still under $1 million. But not hybrid - I'm not sure what that adds.

You can also do a lot of customizing, but that does bring up the cost if you go too far outside the normal design.

How do you know this number?

Hard to tell where the waterline is on that drawing?

Thats silly, the Excess is much narrower at the waterline. And the length to displacement ratio is much more inportant for exceeding hullspeed. Interesting with the asymmetric hulls

Re: Excess 14 new design

not to go a smidge off topic but I am seriously considering a Nautitech Open 44 under the premise that it will have better performance than lets say a Lagoon but not the performance of a Outremer. Has anyone sailed an Open 44 and can confirm this? I too would love a boat with a bit more performance than a lagoon but I dont think I am ready for the Outremer crowd yet

Unless you are flying a hull or there is very significant heel, creating lower hydrodynamic pressure to windward, I can't see the point of asymmetric hulls. The opposing sideways components of each hull when running flat, not heeling, will cancel each other out and simply produce additional drag although it could be argued that there is less wake interaction. It does improve straight line stability at the expense of tacking ability, certainly in beach cats. The asymmetry also widens the CB potentially allowing more sail to be carried at the expense of more wetted surface and less load carrying ability. This maybe a good compromise for the anticipated speed range. I have to say this is still a heavy boat so not significant performance enhancements.



Where did you get the section? Can you estimate the hull beam?

Yes, where did you get this diagram. Does anyone know the hull width of the Excess 14 at the waterline?

No no no, that's not what they wish (Boot Dusseldorf) :
Framed the boat well for the show, didn't it? I'm sure that was the intent, as they are very proud of the 14's hull shape. The 14 is the first hull completely designed by the Excess team and not a Lagoon hand-me-down. Among other things, it's asymmetrical for better performance. While its still a Cat, the effort is to provide monohull performance and actually make them fun to sail, not to be dock dwellers.

On the opposite side of a similar to E14 weight cats line, there are, say, 6 tons (empty) cats with "cruising" sails of 93 m2 (upwind), or "racy" 2 meters taller mast to carry more sail area.

Wow so it's a cat and they want to make it slower?? Haven't seen a mono that could sail as well as a PROPERLY designed and built multi in years.

HA, so you are saying sailing lagoon provides no joy, like driving barge. Regrettably, that is not so. Thinking of our last ~4-5k nm in last year, i can assure you we enjoyed >80% sailing, including upwind. There are those moments choppy after blow and going upwind and against current where i desire mono for couple hours to squeeze that extra 0.5kn of upwind VMG. But yeah, i find these days i put in extra reef by default and we both still fully enjoy sail.

Re: Excess 14 new design

To cover a fair amount of misinformation in this thread, let me add my 2¢. I have been on Excess 14 hull #1 a number of times, including on a three hour test sail where I was at the helm for 1.5 hours. (As full disclosure, based on seeing the boat and sailing it, my wife and I placed an order.)

The boat sails incredibly well. Where it really outperforms some other cats in its size is in light wind. In 6 knots of wind, it happily went 4 knots upwind. In 8 knots of wind it went 7 knots at 90° wind angle. We never had winds over 12 or 13 knots, but at 12 knots it sailed 8.5 knots at 120° wind angle. And it is a joy to sail.

It was specifically designed to be fun to sail, and it really is. With two aft helms, right over the rudders, and dyneema mechanical steeering, it is extremely responsive, and the helmsperson is very close to the water with excellent visibilty all around. This plus a generous sail area/weight ratio makes for very good performance. The boat I was on was fully equipped for cruising, and even had a generator and AC.

As far as the asymmetric hull shape goes, its biggest advantage is reducing interference drag. A great amount of testing was done. For those interested, read the article in No Frills Sailing: https://no-frills-sailing.com/vplp-a...lls-excess-14/ . The Excess team is very happy with the hull shape. I have attached tow phones of how it was displayed a few days ago at the Miami Boat Show, with bow facing forwards.

The Excess 14 has been very positively reviewed in a number of sailing mags: Sailing today Dec. 2022; Yachting World Feb. 2023; Multihulls World April/May 2023. I have attached the specs printed in Multihulls World, as well as an info table on what they think the competition is.

As far as the Excess/Lagoon discussion goes, the first two Excess models, the 12 and the 15, were built on Lagoon hulls. These two models will be discontinued. The two newer models, the 11 and the 14, are original desings by Excess, and use no Lagoon elements at all.

Apart from Performance, my wife and I found the Excess 14 to be extremely comfortable to be a live-aboard. It is roomy with wonderful light in the saloon. We chose the three cabin owner's version, but it is really a 3 1/2 cabin boat--the forward section of the owner's hull is a storage/work area that has two coonvertible single berths.

If anyone has any questions about the boat, just let me know.

Re: Excess 14 new design

Thanks mgholt,
Nice to finally hear some hands on feedback.
Could you elaborate on the performance figures you provided?

Something like sea state (I take perfect conditions considering the response), but also details on TWA, Heading, Leeway ...

Also, what about visibility and hulls noise while cruising?

Thank you

Re: Excess 14 new design

Hi Giova! Good questions.

The sea state was quite calm, as would be expected in the Mediterranean in September when there was almost no wind in the morning, and when we started sailing in the afternoon there was only 4 - 8 knots of wind.

I did take some video when I first took over the helm, when the wind was still light, and I have attached some screen shots of different speeds and wind angles.

The visibility is excellent from the helm, as would generally be expected from two aft helms, and helped by the clear windows which can be seen through well. I have attached a photo shot from the dock of the stern, and here's a link to a Youtube video I shot from the starboard helm under sail: https://youtu.be/yCWj3GPDaDA .

In these conditions, there was no noticeable hull noise.
