Hello everyone. I came here from your former colony (USA) hoping to find a lot of folks who were interested in buying short fiberglass kits of square rigged vessels, but I certainly struck out! Every listing above is about a power boat. However, hope springs eternal. If anyone, anyone is interested in "my" topic (square rigged pond boats) please list the criteria you want the kit to meet, such as hull length (lwl), weight, rig, draft etc. (Any since my education is limited and my dictionary misplaced, American units would be most helpful. i.e. pounds, feet, inches.)
And if anyone is experienced in the design of in-the-water square rigged vessels between 2 and 5 feet lwl please tell me what you know about compensating for the "scale factor." By that I mean I know that the righting moment of a scaled down ship decreases by the linear scale factor to the 4th power while the heeling moment only decreases by that scale factor to the 3rd power, and thus the model is VERY tender. What I am interested in is determining how to increase the righting moment so that the model has "the same" stability characteristics as the full sized prototype. Certainly I can increase the underwater volume of the hull and add a deep fin with lead low down, but how much increased stability do I need? (without making lots of different prototypes to find the answer?)
Any help will be appreciated
Thanks
George Steele
