Seems I get a second chance for my topic - this time even with pictures.
Sometimes I dream about building and sailing a Core Sound 20#3. I love the looks of her, I love the idea of water ballast, I love having a mizzen and this size of cabin and more.
But then : I love my existing boat too - and I wonder how the CS would sail in comparison to her. And I wonder how some people can read performance from the lines or pictures or data.
So here are the basic informations about my boat:
Her name is Muckla and she is a Diabolo, designed by Jüs Segger.
A word about Jüs: he was trained as a boat-builder and became later an engeneer and yacht-designer, drawing and selling plans, mainly for plywood hard-chine-boats, aimed for the amateur-builder...... (anyone heared of a similar career??).
The Diabolo is 20 ft long, has about 190 sqft of working sail area + lapper and/or spinnaker and/or code 0. She has a ballasted centerboard. The lead in the cb is 60 kgs + about 30 kgs of internal ballast + the heavy equipment in the bilge. This gives her a decent end-stability though I doubt if she would be self-righting if necessary. I rather not try. Initial stability is rather low so you can fine-trim her by moving your body. According to the previous owner she weighs about 600 kgs fully equpped.
In about 4 bft on a beam-reach she starts semi-planing with speeds of around 7 kts (hull-speed is just under 6), in a f 5-6 she gets to full-planing. I have read up to 10 kts on the gps so far. So for her size she is quite fast and also well-mannered. Only when reaching in very gusty conditions, she gets a bit catty.
So, all you knowledgable folks: if there was a race between a CS20#3 and a Diabolo - which one would be in front under which conditions - and: how do you know??
I hope, the data + pics give enough information.
Looking forward very much to your thoughts & feelings,
