9592Model in relation to ballast
- May 1, 2005
>>Given the uncertainties of material weight, as well as gear and crew, I would take a pragmatic approach. Build the model, mark the waterline, put the model in the water, and add ballast until the model floats on her lines!Thanks John T. That was the direction I was thinking. In my case, I figure a person could get pretty dang close just referring to historical data. Similar boat/ what ballast. Any discrepancies could be sorted with internal additions....or a Sawzall.
On this topic, I posted the same question to Jim. (as I mentioned before)
His reply was interesting and I thought you all might like to read it as well.
"I'm not sure you can learn anything from a boat model besides what it
looks like. Some folks disagree and Kilburn Adams told me he worked the
bugs out of his Skiff America design with a large powered RC model. As
for ballast calcs, they are related to stability. A lot easier to do now
that we have programs like Hullform. It the past it usually was not
calculated, only based on experience. I wrote an essay about the topic
based mostly on how to figure how much sail your boat can carry."
Does anyone know the title of that essay?
