Los Angeles SNAME And ASNE Sections Meet In Joint Session

The Los Angeles Metropolitan Section of The Society of Naval Architects and Marine Engineers, in a recent joint meeting with the Long Beach-Greater Los Angeles Section of the American Society of Naval Engineers aboard the SS Princess Louise I, heard two presentations.

The first was entitled "Consideration of Maneuverability Characteristics in the Rudder Design Process," by Dr. Volf Asinovsky, senior naval architect in -John J.

McMullen Associates' Arlington, Va., office. The second, a student paper provided bv ASNE, was entitled "A Short History of the Sea Explorer Ship Shipjack and Their Boats," by Gregory K. Ramsey, a student at the California State University in Long Beach.

Dr. Asinovsky's paper discussed the correlation between the kinematics of ship motion and the hydrodynamic force developed by the ship's rudder. The author amplified his presentation with mathematics and illustrations showing the relationship between movements of the ship's CG and those of the rudder, along with charts of rudder torques and other characteristics.

Mr. Ramsey's paper, which won the $100 prize in the local ASNE/ SNAME Student Paper Competition for 1985, dealt with a local group called a "ship" of Sea Explorers (formerly Sea Scouts), their various boats, and their activities through the years. This included the story of their overhaul, outfitting, and re-engining of a former Navy MSB-5 Class minesweeper in the mid-70s.
