Celeste 34 Sport | sail plan

This is the second article after our test sail a couple of weeks ago. Part one covered deck layout and systems and this time we’ll focus on sail plan and performance.

  • Sizing of sail plan – using ORC VPP
  • Reflection – how did it feel
  • Sail inventory – in-depth on all the sails

One of the things often debated with new boats is sail area vs displacement or other numbers indication horsepower to weight. As with sports cars, you can make a lighter car go with a smaller engine (a la our J/111 that was considered underpowered when it launched) or make a muscle car when you put a V8 into a beast of a car (a la a Class 40).

Finding the right balance is delicate. What’s right for a keen regatta sailor in the archipelago is different from what a cruising family wants for longer cruises.

For Torbjörn Hurtig, the owner, it was clear that he wanted to bring the J/80 experience into a bigger package. So plenty of horsepower.

In a bigger project, there’s usually a big budget and lots of computer power to figure this out. Instead, the project team with North Sails, Seldén, Gabriel Heyman, and Torbjörn decided to use the ORC VPP to run a range of rigs to see how the boat performed in different conditions but without bringing the rating itself into the equation.

Boat speed in different wind strengths. It’s clear that the boat would benefit from a taller rig in 6-8 knots, typical Scandinavian summer-conditions. And there’s a real risk of becoming underpowered.

Looking at heel, reef and flat it’s also easy to see when the boat becomes overpowered and you need to reduce sail.

An additional benefit is that you get crossovers straight out of the ORC Speed Guide as well as target speeds.

The same tools are used to optimize an existing boat and it’s possible to run many sail & weight combinations, trying to figure out if you get more speed vs the rating hit. Or not. 😃

Enough with the theory.

How did it sail? Was it overrigged?

We had SW 14-18 knots with 20 in some puffs. So potentially overpowered without a crew or water ballast?

But she behaved very well, balanced and actually easier to handle than a J/111 in the same conditions. I was somewhat surprised, as I expected the sail plan to be a bit much in these conditions.

With water ballast, full main and the big jib will work great in 16 knots, at least with active trim and a good autopilot.

We also tried out the inner jib that looked great. But it will probably come into play when the wind is steady at 18-20 knots.

Going back home, we hoisted the 108 m2 A3. Plenty of punch in the gusts and we touched 14 knots. We also tried some broaching 😱. This will be a fun ride downwind both in light air, and when the boat gets on a plane. Also in combination with the big 130 m2 A2, there will be plenty of power in most conditions.

Overall, pleasantly surprised.

Good job by everyone involved.

Main

3Di Endurance 760 S 14,700 Dpi, 40,2 m2, ORCi 38,67 m2
Endurance 1010 – White

Note the big roach with several longer battens but just one full length at the top. Very similar to the ClubSwan 42? Supposed to give both control as well to be easy to tack/gybe in higher winds without getting stuck. Looks cool!

J2 Allround Jib

3Di Endurance 760 S 14,700 Dpi, 32,9 m2, ORCi 31,63 m2
Endurance 1010 – White  
Vertical battens
3D Furl Only Structure (no reefing)  
Headsail Half Reef (reaching clew)
Soft hanks

Designed with a sweet spot at 12 knots, but the structure should take some beating in more wind.

Similar to the shorthanded jib we have on Blur.

J3 Inner jib

3Di Endurance 760 S 14,700 Dpi, 19,91 m2, ORCi 19,52 m2
Endurance 1010 – White 
3Di Offshore Ply
Headsail Half Reef (reaching clew) 
Custom cable

Set on a furler with a halyard lock (see the previous article).

Should be able to be used as a staysail in combination with the code and maybe with the J2 sheeted in the reaching clew?

Code 55

(Force F-Zero) NPL Code Xi Xi09 CD, 55,6 m2, 54,02 m2
Soft Clew
Custom cable

Set on a furler with a halyard lock.

A2 Asymmetric

Superkote 75, 132,85 m2, ORCi 128,97 m2

A3 Asymmetric

Superkote 130 – 90, 109,3 m2 ORCi 108,22 m2

Storm Jib

Polyester High Visibility 8oz Storm Orange, 8,30 m2
Set flying as inner jib.

A happy owner, Torbjörn Hurtig. And a relieved sailmaker, Henrik Ottosson from North Sails.

Mission accomplished.
