Looks good in a conservative sort of way
If the 380 is comparatively as fast as the 340, the performances would not be conservative, as the looks, but outstanding.
Let's compare it with the Salona 38, a reference in that size and segment:
The Arcona is smaller (11.28 to 11.50m), heavier (6850kg to 6500kg) beamier (3.80m to 3.62m) with about the same B/D ratio (35%) but while the standard draft of the Salona is 1.98 the one from Arcona is 2.10m and while the Arcona keel is a bulbed one the one from the Salona is a more efficient torpedo keel.
In the end the RM provided by the keel should be similar but the Arcona will have more form, stability. Curiously with that extra stability the Arcona has not more sail area but a bit less ( 86.5 to 88.40m2). I would say that it would need more sail area to compensate the extra beam...but anyway the performances are going to be close.
The designer, Stefan Qviberg , (the same that designs all other Arcona) says about the Arcona 380:
"Early 2000's I was commissioned to design the Arcona 400 and 370 - my goal then was to design something completely new and unique - the ultimate cruiser / racer. A family boat of world class and a racer that would compete well in both in regatta and ocean racing. 14 years, more than 300 delivered boats .... speak for themselves...
Development has since moved with incredible speed... and stimulates now boats with high stiffness and large sail area - for speed in all winds.
...The mission is the same as 14 years ago, but today the competition is considerably tougher. The market offers a large number of boats with different characteristics and qualities in size from 38 to 40 feet...
We will build another elegant perfomance cruiser, a boat with a unique feel and unsurpassed sailing pleasure!
The classic Arcona profile will remain as model as well as comfort and style. A feeling that can only be created in the harmony between thought-out function and woodwork in classic materials and of the highest caliber.
Arcona 380 is going to be easy, stable and deliver a sailing experience far beyond the ordinary. The hull is a natural extension of the line that began with successful Arcona 340. Sailing characteristics of the 340-ball has surpassed even my expectations (2nd on ORCi Championships in Santahamina, total victory Ornö Around this year, etc.). Arcona 380 is a direct development of this model.
Hull, deck and inner liner will be produced with the infusion method, which ensures optimized weight and quality.
Arcona 380 will have a sail plan with non-overlapping headsail and a, relatively speaking, somewhat larger mainsail than previous models. Everything to simplify management and keep costs down on the sail wardrobe.
High stability will be achieved with the same type of composite steel fin with lead bulb of the previously models. .."
The boat is going to hit the water in the Summer of next year...and it seems that they will deliver 5 boats in the Summer, all already sold on the drawings. Now, that is impressive since the boat will only be presented in the Spring.
