Maritime Mathematics Summer Content Institute for Teachers

Maritime Math Second Week
First Day

This Summer Institute began last week at Bridgewater State College with five days of intensive work led by Tim Mitchell, Paul Anthony, Ron Norsworthy and Frank Guiliano and hosted by the Southeast PALMS Coalition.

On the second week the Institute came to New Bedford for an intensive, hands-on five days. Images from the first day are shown to the right.

Today's Topic: Hull Design and Working the North Atlantic

z Ship Stability
Hull Speed = 1.34 times the square root of the hull length at waterline

Roll Period is inversely related to the stability

z Displacement
The mass of water displaced by a hull equals the mass of the hull

For two forces in equilibrium on a lever, the force times distance from the fulcrum of one equals the force time distance of the other

z Center of Mass and Specific Gravity
Density of a substance divided by the density of water equals the specific gravity of the substance

z Working with Lines Drawings
