All American Marine has Delivered an Innovative Research Vessel for the University of Hawai’i at Mānoa

All American Marine (AAM) together with the University of Hawai’i at Mānoa are proud to announce the delivery of an innovative research vessel, on behalf of the Hawai’i Institute of Marine Biology (HIMB). This state-of-the-art research vessel, IMUA, is a 68.5’ x 25’ semi-displacement aluminum catamaran hull that was developed by Nic de Waal of Teknicraft Design in Auckland, New Zealand. The vessel contains proven design elements found in the recently commissioned and successful research vessels “Blue Manta” and “Shearwater” built for BlueTide Puerto Rico and Duke University, respectively.

The vessel was constructed to US Coast Guard (USCG) standards and will operate as a multipurpose research vessel in the Hawaiian Waters and Offshore on Ocean Routes. The twin-engine speed and fuel-efficiency of this vessel will be fundamental to meet the University of Hawai’i’s research goals and allow them to access and study marine environments in the Hawaiian Islands. The knowledge gained from science missions on this vessel will directly support the management and conservation of Hawaiʻi’s marine resources.

“From the beginning, we had productive discussions with All American Marine. This allowed them to understand exactly what we wanted from this vessel. I’m very impressed at her speed and handling, even with all our scientific payload on board.  Our opportunities to conduct research in certain oceanic areas around Hawaii are contingent on fairly good sea conditions. The ability to get to these remote places quickly with IMUA means considerably more opportunities to leverage weather using this vessel compared to a traditional, rather slow research platform”

The new research vessel integrates the signature Teknicraft Design symmetrical and asymmetrical combined hull shape, bow wave piercer, and a patented hydrofoil-assisted hull design. The hull and hull components are designed to break up wave action and ensure reduced drag while enhancing passenger comfort.  Teknicraft’s innovative dynamic hydrofoil-assisted hull design is proven to have industry leading low-wake wash energy and fuel econom. The main foil action reduces the power needed to maintain service speed; therefore, fuel consumption and running costs are reduced significantly, while also further enhancing the softness of the ride, especially in choppy seas. Teknicraft’s unique hydrofoil system consists of the main foil spanning the tunnel at the keel. This vessel also included transom mounted Humphree interceptors. The lift produced by the hydrofoil reduces the hull resistance while increasing speed and load-bearing capability, while the interceptors offer additional trim control.

This advanced hull shape was custom designed using digital modeling and Computational Fluid Dynamics (CFD) analysis testing.  The vessel’s design offers all passengers and crew a smooth ride and comfort, as the hull provides a cushioned effect when encountering waves.  For the operator, one valuable feature of this vessel is the excellent fuel economy, while also maintaining an estimated fully laden cruise speed of 22-24 knots and with a fuel-efficient minimum survey speed of 3 knots. With a large fuel capacity of 1800 gallons, this design will support a science team of 8 on offshore multiday missions and 22 students/crew on shorter day excursions. The propulsion package includes 2x fixed pitch propellers, powered by twin Scania DI16, 082M, Tier 3 engines, rated at 800 mhp @ 2100 RPM. Onboard the vessel, scientists and crew have comfortable live-aboard quarters, large state-of-the-art wet and dry lab spaces, as well as a range of the latest oceanographic equipment in which to conduct a variety of missions. The vessel was custom designed to support a diverse portfolio of science and outreach missions including advanced studies on marine megafauna, pelagic and coastal ecosystem research, oceanographic surveys, and K–12 learning experiences.

“All American Marine remains committed to being on the leading edge of manufacturing techniques and an innovator in merging the latest technology into a functional and proven vessel. We are thrilled to have built this multi-mission research vessel and put it into action. It paves the way for a new era of ocean conservation and research capabilities.”
