68’ USACE Philadelphia

USACE Philadelphia “Killcohook”: High-Speed Hydrographic Survey & Dive Operations Vessel

All American Marine (AAM) proudly delivers the Killcohook, a 68-foot hydrofoil-assisted aluminum catamaran, designed for the U.S. Army Corps of Engineers (USACE) Philadelphia District. This advanced survey and dive operations vessel supports dredging projects and hydrographic research, ensuring efficient and precise data collection for waterway maintenance.

Innovative Teknicraft Hydrofoil-Assisted Design

Designed by Teknicraft Design Ltd., the Killcohook integrates:

• Teknicraft’s signature hull shape, featuring a symmetrical bow, asymmetrical tunnel, and integrated wave piercer for enhanced stability and efficiency
• Custom aluminum hydrofoil, generating lift to optimize speed, fuel efficiency, and performance
• Lightweight aluminum construction, ensuring durability and high-speed maneuverability

With over 20 years of hydrofoil-assisted vessel expertise, Teknicraft continues to lead in high-performance marine design, delivering cutting-edge solutions for survey and research applications.

Powerful Propulsion & High-Speed Performance

Equipped with a high-power propulsion system, the Killcohook features:

• Twin Caterpillar C18 diesel engines (1001 bhp @ 2300 RPM) with EPA Tier III emissions compliance
• Twin Northern Lights C40M.3 40kW generators for auxiliary power and onboard systems
• 28-knot cruise speed (31-knot max speed) for rapid deployment to survey sites

This high-speed capability allows the USACE Philadelphia District to maximize on-site research time and enhance survey efficiency.

Advanced Survey & Dive Operations Equipment

Designed for multi-mission capabilities, the Killcohook is equipped with:

• Hydraulic A-frame & davit, supporting heavy scientific equipment deployment
• Scientific winch & moon pool with deployable sonar strut, ensuring high-precision hydrographic mapping
• Integrated dive platforms, allowing for safe and efficient dive operations

These features enable the Killcohook to conduct thorough underwater inspections, supporting dredging, environmental monitoring, and marine infrastructure projects.

Enhancing USACE’s Hydrographic Research Capabilities

Following the success of the 62’ Florida II, previously built by AAM for USACE Jacksonville, the Killcohook continues to set new standards in hydrographic survey vessel performance.

Built at AAM’s Bellingham, WA facility, the Killcohook delivers unmatched speed, precision, and multi-mission capability, ensuring faster, more efficient data collection to support waterway maintenance and dredging operations along the East Coast.
