Hi Ron and Tony, are your Dragen yachts static or for sailing?
Over 20 years ago now I was asked to build a Dragon Class yacht by Int. Mar. Modelling but using a ready made glass fibre hull about to be marketted. It was with a view to have a sailing model.
Don't get excited, when I received it the hull was very heavy with the hull about 5mms thick. I had an Inga IV hull at the time and it was 50% heavier than the much bigger Inga IV..
It was too heavy to have a lead keel and float any where near the waterline. I did give them feedback but no response, the model yacht was never built (by agreement) but I had done a lot of research including a visit to builders in Essex.
Most Dragons are open cockpit however there are a few non-racing ones with a closed in one. As you will know they are a Norwegion design from 1929 and were used in the Olympics as a class from 1948 until 1972.
Always regarded as a handsome design that has stood the test of time. Sarik carry a plan called Bluebottle which was the Dragon Class yacht which was presented to the D of Edinburough. The plans were in Model Maker many years ago together with a write up on building.
These plans show several sail plans and for a sailing model I would suggest the smallest set of sails as best.
I later had experience with a metre long sailing model of the UK Americas Cup Endeavour our 1934 entry. This was grossly over canvassed and benefits from cutting back the sails.
Sailing boats can look very nice heeled over but the most efficient way to sail is to be as upright as possible.
Regards
Roy
