Find the right research vessel for your project.

URI scientists rely on a number of small research vessels for sampling, tending to deployed equipment, diving operations, and more. Brian Caccioppoli leads the Small Boats Program, which helps to manage GSO’s smaller research vessels. If you are interested in using one of our small boats, contact Brian at bcaccioppoli@uri.edu.

The boats below are currently active and ready for use.
- Marlon Jon boat, 14’ jon boat.
- NorthWind 23, 23′ rigid buoyant boat
- Lyman Morse 26, 26’ aluminum boat
- R/V Warfish, 45’ Downeast style lobster boat
Marlon Jon boat
The Marlon jon boat is a 14’ flat bottomed welded aluminum hull with a 20 horsepower tiller-operated outboard engine. The flat bottom shape of the hull makes the boat very stable with a very shallow draft, allowing it to carry up to 4 persons or 6xx lbs. It is suitable for inland waters including rivers, lakes and coastal lagoons. The boat has a dedicated Load Rite trailer.

Northwind 23
Northwind 23 is a 23’ rigid buoyant boat, with heavy duty welded aluminum construction and a pressurized foam sponson. The heavily built deep vee hull and open center console layout makes for a very seaworthy vessel with a dry ride. The Northwind is scheduled to be repowered with twin 115 horsepower Mercury outboard engines in Spring 2026. The boat features low gunwales, allowing for easy sampling and deployments. The towing bitt and engine guard rail make it useful for net tows, and the boat features a dive ladder for dive operations.

Lyman Morse 26
Lyman Morse 26 is a 26’ pilothouse style aluminum work boat. Designed by Bill Lincoln of Response Marine, and built by Lyman Morse Metal Fabrication, the hull was specially designed for enhanced stability and handling at rest and at lower speeds, typical of oceanographic sampling.
The boat is powered by twin 200 horsepower commercial duty Mercury outboard engines. The boat features an aft towing bit and engine guard rail, a starboard dive door with removal ladder, davit with electric winch, starboard side pole-mount system and auxiliary sensor rail mounted above the pilothouse. The pilothouse and cabin spaces are heated, with bench seating and a fold up table, and a portable marine head.
Two 8D lithium iron phosphate batteries and inverter charger provide 120V power. Garmin multifunction display with GPS, radar, spotlight and ample deck lighting make day or night operations safe in Narragansett Bay and RI coastal waters. The boat has a dedicated Venture trailer.


R/V Warfish
R/V Warfish is a traditional 45’ Downeast style lobster boat built by Provincial Boats outfitted for coastal oceanographic research. Warfish is named for the man-of-war fish Nomeus gronovii, a unique fish that lives within the tentacles of the Portuguese man o’ war. The boat was previously used for shark research, media and conservation. At its new home at URI GSO, R/V Warfish will serve as a floating classroom for marine science classes and facilitate coastal research throughout Narragansett Bay and the Sounds.
Warfish is a USCG designated uninspected oceanographic research vessel and is well outfitted for science with multiple hydraulic winches and cranes, swim platform, dive ladder, observation pulpit and layers of redundancy for added safety and capability.

How do we use our small boats?






SBSA and MOTC
The University of Rhode Island is an organizational member of the Scientific Boating Safety Association (SBSA) and a regional provider of the Motorboat Operator’s Training Course (MOTC).
The MOTC is an immersive 4-day introductory boating safety and survival skills training course. The course is a professional boating standard designed to train scientists how to use small power boats for scientific missions. The foundational knowledge and skills learned in the MOTC include navigation rules, federal and state boating law, boat handling, seamanship, trailering a boat and self-rescue, emergency, and survival techniques. The MOTC is accepted by the US Department Of Interior, NOAA and other SBSA-member institutions. The course utilizes the URI Narragansett Bay Campus, URI Tootell Aquatic Center and URI Allen Harbor Facility.
The MOTC is offered on an annual basis, typically at the conclusion of Spring semester. Please contact Brian Caccioppoli for more details and coming courses.
