Maurício Dantas

Mauricio Dantas is a Brazilian living in Texas – USA which has helped a lot this blog. Thanks to him, Eric Rosembaun allowed us to publish several articles on the blog. Some time ago he sent me some pictures of a spectacular and very simple tool to find the longitudinal center of gravity of RC sailboats. It’s very simple, see the photos:

To use it just put the boat on top, taking care that the design waterline (you need drawing it on the hull) should be horizontal with the boat balanced on top of two rods. There, the distance from the stern to the rods is the longitudinal center of gravity of the mass of the boat, referred to the stern. The center of gravity should be exactly in the same position of the longitudinal Center of Buoyancy,  to meet design conditions.

Maurice told me it is used to find model air planes center of gravity.

Maurice sails (and well, won some races  in Texas) a class not known in Brazil , the Victoria, as well as IOM and RG 65.

This tool is so important.

Thanks Mauricio!
