Go to:
http://www.viksund.no/forum/viewforum.php?f=15
You have some info about this boat there, although you'll probably need traduction services...
There is an owner of a Vicksund 31 who contacted me because of my pages about Motorsailers & Motorsailing, seeming to be pretty well informed about Vicksunds,with whom I can put you in contact.
E-mail me.

Hi and thanks for the reply, I saw that page the other day but I dont understand anything. Do you think a motorsailer 27 can capsize more easy than a sailboat?? My wife its concern about that. Thanks again

I have seen those boats around, and the use their engines quite often.
I think they have quite small sails and a large wetted surface (long keel).

LOA: 8.05 m
B: 2.80 m
Draft: 1.05 m
DIESEL: 80 l
Water: 80 l
Engine: 15 - 70 hk
Speed: 6 - 11 knots
Weight: 3000 kg
Produced 1970-1980
Two different rigs, 17 or 25 m2.

Hi,do you think a boat like that can capsize easy?? what its your opinion on put a couple more feet of mast a sails?? I only wanted to reach and downwind because a lot of little toll me its impossible to go windward with a boat like that. My father have a Morgan 41 Out I the hull looks very similar to the viksund 27 long keel but with short draft and a square rudder we never can point to much to windward we always use the motor to do that. Thanks for the next opinions. Mario

I do not see a particular risk of capsizing for well designed traditional motorsailers against 'sailing' boats.
There is a Capsize Ratio that may be used to roughly have an idea about the risk of capsize for a certain boat. It is:
CSF = Beam / (Disp/64.2)^1/3
This number being lower than 2 indicates a lower risk of capsizing than being over it.
Here you have several Capsize Ratios for motorsailers with lengths close to the Vicksund's:
LM27: 1.79
Dartsailer 27: 1.80
Degero 28: 2.01
Vancouver 28: 1.67
Finnsailer 29: 1.70
Fisher 25: 1,73

Using main characteristics provided by Raggy Thor for the Vicksund:
Vicksund: 1,96

On the other hand, here you have more 'sail power oriented' motorsailers:
Kodiak: 2.13
Freestyle 27: 2.7

You can see here that motorsailers are not necesarily riskier than 'sailing' boats.
Cheers.

Vicksunds have a SA/D ratio of 12.21 for the 25 sqm rig and 8.30 for the 17 sqm one.
With the lower engine power mentioned by Raggy (15 hp), you get a 6*HP/D ratio of 13,60 and with the higher (70 hp) you get 63,45 (!)

If you finally go for a Vicksund, I recommend you to search for a unit with the 25 sqm sail area and engine power not in excess of 20 HP.

Increasing sail area over this will most probably require a detailed study of its feasibility by an expert.

Traditional motorsailers require precisely that: Motorsailing when beating to winward.
