On October 3, 2002, Washburn & Doughty Associates, Inc. of East
Boothbay, Maine delivered Kittiwake, a 72' x 20' x 10'6" Offshore Motor
Vessel, to Hempstead Navigation Service LLC of Exeter, Rhode Island. The
vessel, which is designed for long distance travel, has a steel hull
(5/16" shell) and an aluminum deckhouse.
Hempstead Navigation Service's core business has been contracting the
delivery of military and commercial vessels worldwide, and compass
adjusting and repair when not otherwise at sea. With the delivery of the
Kittiwake, company owners Robert Hempstead and Letitia Davis
, a husband
and wife team, plan to expand their business to include training in
advanced navigation, seamanship and shiphandling aboard Kittiwake.
Additionally, they plan to operate her as a research platform for
smaller research projects. These programs will draw on Hempstead and
Davis' years of experience at sea. Hempstead, who is on his 9th issue
of his Unlimited Masters, Oceans and Pilot License, Sail & Steam, with
close to 2 million miles at sea, formerly operated research vessels for
URI and Woods Hole Oceanographic Institution. Davis holds a USCG
license as Mate, Oceans, 1600 tons, with over 60 commercial and military
vessel deliveries worldwide to her credit.
Hempstead and Davis decided that Washburn & Doughty was the yard to
build the Kittiwake after an extensive search of other yards building
similar vessels in steel, aluminum and fiberglass. Hempstead states, "We
wanted a vessel of heavy scantlings that could be designed by the
builder in-house, allowing him to exercise his strengths in his building
practices. We had heard a number of favorable reports on the quality of
W&Ds steel work, and most importantly, the builder's integrity in
delivering a good product while taking no short cuts."
Kittiwake features a Caterpillar (CAT)
3406E main engine rated at 450hp at
1800 rpm. The vessel has a top speed of 10 kts, and uses a Twin Disc
5114 reverse gear with a 4.17 to 1 reduction ratio turning a 4" Aquamet
22 shaft, and a 48" 5 blade NiBrAl propeller through an Aquadrive unit.
Two generators, a Cummins (CMI)
Onan Model 35 MCGBA (35KW) and a Cummins Onan
Model 17.0 MDKAD (17KW), fulfill the vessel's electric power
requirements. A 4 KW Trace Inverter system provides limited AC power,
thus reducing generator usage when only light power demands must be
satisfied. A Charles 50 Amp Iso-Boost Transformer provides electrical
isolation and corrected voltage when plugged into shore power.
The vessel is equipped with an American Bow Thruster 16" TRAC series
thruster hydraulically powered from the 35 KW generator. Controls are
installed at the pilothouse and bridge wing stations. In addition, the
bow thruster's hydraulic system is designed to chain drive the main
propeller shaft and thereby create an emergency take home system.
Hempstead and Davis put extensive thought into the vessel's bridge. The
vessel is outfitted with a Simrad #AP-45 Autopilot, Furuno #8111 Radar
with ARPA capability, Furuno #FCV-582L depth sounder, Furuno #SC-120
Satellite Compass, which also drives a Plath gyro steering repeater,
Northstar #951XD GPS, Icom #710 SSB radio, Icom #127 and #520 VHF
radios, and a Furuno NX300 Navtex Receiver. Steering is by a Jastram
system featuring 45° rudder angles with a hard over to hard over time of
13 seconds. Back-up exists in all major systems aboard. To assist a two
person operation on long passages, a day berth and head were installed
in the pilothouse. Unlike most modern vessels there is no helm chair at
the wheel. On the Kittiwake, watch standers will follow tradition and
stand their watches.
Kittiwake's interior is finished with off-white formica-faced plywood
and teak trim. The interior's overhead is sheathed in foam backed
Majelite panels for sound reduction. The comfortable and well-appointed
master and guest staterooms feature queen and full size berths
respectively, ample storage and private heads. The crew stateroom is
outfitted with two single berths, two roll-up pipe berths, and a private
head. In addition, Kittiwake features a spacious lounge area, an office,
and a fully equipped galley. The galley was designed for Davis, who
loves to cook. It features a professional quality Viking stove, Corian
counter tops and under-cabinet lighting.
The vessel has a 6,000 gallon fuel oil capacity for a 3500 nm cruising
range; 225 gallon lube oil capacity; 225 gallon dirty oil capacity; and
a 1,500 gallon potable water capacity supplemented by a 600 gpd reverse
osmosis water maker.
After delivery, Hempstead had this to say about his experience at
Washburn & Doughty and his new vessel, "This shipyard showed noteworthy
ingenuity in meeting the many challenges presented by the installation
of the numerous features required in this vessel. We were particularly
impressed by the skilled workforce and the trades' leadmen. A lot of on
scene creativity was required. They delivered this and with a splendid,
can-do attitude. The personal integrity shown in all our dealings from
the top down was refreshing. We believe Kittiwake will prove, as her
design intended, to be an able and comfortable vessel well suited for
