[1]: 164 As this growth was underwater, removing it was difficult. Beaching ...
New ship being prepared for launch, showing fresh anti-fouling paint Ship hull being cleaned of fouling in drydock. Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability.
In September 1964, Time magazine reported on the vehicle's unique specifications, stating that its 51-foot (16 m) hull consists of 11 forged cylinders. Aluminum's strength-to-weight ratio exceeds that of steel, so Aluminaut 's 6.5-inch-thick (170 mm) shell could withstand pressures of 7,500 pounds per square inch (52 MPa) at the sub's 17,000 ft ...
