The two crewboats shipped to Egypt earlier this summer also were designed by Mr. Preston, and built by AAA Builders, Inc. of Pascagoula, Miss. Each boat is 32 feet long and powered by a GM-Detroit Diesel Allison engine developing 128 bhp at 2,800 rpm. The crewboats each carry 20 passengers, protected from the weather by a canvas awning.
