JMS Naval
Architects & Salvage Engineers (JMS) has acquired Roger Long
Marine Architecture Inc. (RLMA). The acquisition includes
exclusive rights to RLMA's enormously successful CHALLENGER
class fast research vessels. Roger Long, RLMA's founder and
principal designer, has become senior design consultant to
JMS' research vessel design projects. JMS and Roger Long
have collaborated on several projects in the past and have
merged their resources to expand the CHALLENGER Class
research vessel to new markets.
The R/V GULF CHALLENGER was designed and built in 1993 for
the University of New Hampshire and immediately demonstrated
that a small, fast research vessel can offer slow-speed
efficiency and comfort equal to or better than heavier
displacement vessels. Follow-on vessels in this series
include the R/V FAY SLOVER selected as one of the 10 most
significant vessels of the year by American Ship Review, the
R/V TIOGA owned by Woods Hole Oceanographic Institution, and
most recently the 81'' R/V RACHEL CARSON launched in 2008
and owned by the University of Maryland. With a pair of
1,200 HP jet outdrives, the R/V RACHEL CARSON cruises at 24
knots allowing researchers more time on station and less
time in transit; both of which result in significant savings
in time and operational costs.
“Designers of things usually see their job as pleasing
the client. I have often said during kick-off meetings and
selection interviews that my objective is not to design the
vessel that the client wants. My job is to design the vessel
that they would want after a year or two of experience
operating it.” ~

R/V GULF CHALLENGER
- University of New Hampshire
This ground breaking vessel demonstrated that a small
research vessel could operate at planning speeds and still
have slow speed efficiency and comfort equal to or better
than
heavier displacement vessels. This design changed the nature
of coastal oceanography and nearly every major university
acquisition since in this size range has been based on the
“R/V CHALLENGER” design.

R/V FAY SLOVER
- Old Dominion University -
Norfolk, VA
This design was an enlarged version of the R/V GULF
CHALLENGER.
This vessel was selected as one of the 10 most significant
vessels of the year by “American Ship Review” in the
2003-2004 issue. The crew of the R/V FAY SLOVER is skilled
in vessel operations with collective experience from the
Corps of Engineers, NOAA, EPA, and private research. All
crewmembers are licensed with the US Coast Guard for 100
Gross Tonnage, near coastal operations. On-board scientific
equipment is maintained by a pool of ODU marine technicians.
At cruise end, the researcher will have the ability to
obtain a CD-ROM with a complete geo-referenced data file of
ship-collected and researcher-collected integrated data in
Labview format.

R/V TIOGA
- Woods Hole Oceanographic Institution
The hull of the Fay Slover was lengthened by 5 feet to
produce greater propulsion efficiency and additional deck
space. The usage and utility of this vessel have far
exceeded the original design brief and operational plans.

R/V RACHAEL CARSON
- University of Maryland
The R/V RACHEL CARSON is based on the “CHALLENGER / TIOGA”
hull form with extensive modifications to accommodate a
water jet drive. It is one of the smallest dynamic
positioning vessels in the world and has proven highly
successful in service. The 81-foot, aluminum-hulled vessel
was built by Hike Metal, and christened in November 2008.
PRINCIPAL CHARACTERISTICS:
-
Length: 81'
-
Beam: 18'
-
Draft: 5'-6"
-
Main Propulsion: Twin MTU 10V-2000
M72 Diesels with Hamilton HM-554 Water Jets
-
HP: 2,400
-
Speed: 19 knots cruising, 1.5
knots minimum

140’ SHOAL DRAFT RESEARCH VESSEL
- Concept Design for Florida Institute of Oceanography
This unique vessel is designed primarily for conducting
multidisciplinary studies in inshore waters but is be
capable of offshore work as well. It would be able to
transport large amounts of equipment and investigators
throughout the Caribbean basin and conduct river, estuary,
and coral reef studies on a scale that have not been
possible before. Water jet thrusters at the bow and stern
will each be directable through 360 degrees allowing the
vessel to move in any direction, including sideways, and
maintain precise positioning. The thrusters will also
provide propulsion with no exposed rotating machinery to
endanger marine mammals, divers, ROV tethers, or
ecologically sensitive bottom habitats. Diesel electric
propulsion will permit immediate switching between screw and
thrusters so that all docking, station keeping, and close
quarters maneuvering may be performed with thrusters alone.
The main propellers will be used only when their higher
power and efficiency are required for cruise.
The propulsion engines and generators are located in the
forward end of the vessel with exhaust pipes led through a
narrow forward stack. This arrangement reserves the most
comfortable parts of the vessel for labs and accommodations
and keeps the noise and exhaust fumes as far from the
working areas as possible. Ironically, the forward stack
contributes to excellent visibility since its narrow profile
obscures a smaller arc of the horizon than one of the
pilothouse window frames. The lack of a large uptake stack
close to the pilothouse permits windows which provide full
360 degree visibility around the horizon. The pilot house
floor is dual-level so that the vessel operators may see aft
over the heads of equipment operators and observers. Floor
to ceiling windows on the aft side of the pilothouse will
provide an exceptional view of the working areas from the
main control station.
