U.S. Coast Guard Patrol Boat (WPB) Hydrofoil Feasibility Design
Abstract
A WPB hydrofoil (WPB-H) feasibility design to meet specific U.S. Coast Guard requirements was developed. This report contains the technical details and conceptual drawings of the WPB-H design. Included are a description of the physical characteristics with a weight breakdown, in addition to engineering and operational characteristics. This baseline, 35-knot fully submerged hydrofoil at a full load weight of 137 L tons, satisfies the 5-day USCG mission requirement at a 30 knot foilborne cruise speed and a 12 knot hullborne speed. The ship's crew of 16 consists of 2 officers, 2 CPOs and 12 enlisted. The WPB-H payload of 12.5 L tons includes 2.5 L tons of armament. Two variants were investigated to determine the impact of increasing and decreasing design speed by 5 knots. It was concluded that the 30 knot design does not offer any significant advantages over the 35 and 40 knot designs. The higher speed variant provides a 5 knot greater speed than the baseline with no technical penalties. Keywords: Patrol boat, Range, motions stability, feasibility design and weights.
