Can anyone help??? 

 I am considering a purchase of a Supernova 30.  It is circa 1975 built 30 foot keelboat almost certainly a half tonner built by Gardas marine Poole The boat has been modified to a masthead rig. and has been quoted as havbing a IRC handicap number of 0.93.  It has  a RCA Dolphin 12 hp petrol engine.We would expect to use it both for club racing in handicap fleet and cruising in the Irish Sea  
Has anyone sailed one of these, if so what is your opinion of sailing/cruising and racing
Does anyone have any views on the RCA Dolphin engine.

 

Hope somebody out there can help as there seems to bea complete derth of information on this boat

Is the pertol engine inboard or an outboard? It would be strange to have a petrol inboard on a yacht surely?
Needs to sail more...

That's a lot for a 30+ year old 30 footer. I'd expect something around 0.90. As an example, S/33s are currently rating 0.925.

  Thanks for your interest Stefan.  I agree that 0.930 is very high fora 30 year old design however it is the only information I have to go on.   The only boat I can find that appears to be of this design is  listed is a Supernova 31 and is a boat called Demolition listed on the Half tonner web site. I have written to the listed owners to ask for their advice

Hi Stefan - guess you mean Sigma 33 and their one design rating is 0.915 which is low even for a boat that pushes a lot of water around especially downwind! See you for the Nab race on Saturday.

You mean next Saturday! Had me worried there for a minute. I obviously found an old figure for the S/33. Bandit rating now! Never mind, we'll show them our transom.

Demolition races against us (Projection 762) at the Helford River Sailing club (google for website).  A nice half-tonner with IRC rating of 0.927 - reasonably well optimised I would suggest.

She competed in Dartmouth this year with some success, but not as competitive as Per Elise, Falmouth half-tonner, who was 2nd in 2007 Half-Ton Cup.

Thanks Gareth,

That is really useful and intersting info.  I did get a reply from the owners of Demolition which also helped to build a sort of picture.  As for the sale am going off the idea unless the seller drops the price, too much work to do and money to spend

Thanks again

I am pretty certain that you will get lots of help from Stephen Jones who, from your description designed and probably helped to build 'Supernova' a masthead 1/2 tonner - the original at least had a distinctive deck. Supernova was a forerunner to 'Demolition' and Smiffy and then the Hustler 32. A Masthead Hustler 32 which I presume to have similar dimensions rates about 0.910.

If possible ditch the dolphin which is probably still located in the bow for the IOR rating.
