Construction
of the Polly L began in January 1999 [Keith
Marine] following
years of Amelia's research and development of
lift boat technologies for coastal shipwreck
salvage. The Polly L was launched for sea trials
in the spring of 2000, to concurrently test both
the Polly L's systems, and a huge new excavator
designed by MacTaggart, Scott & Co. of
Scotland. In the autumn of 2000 the Polly
L was retrofitted with three feet of
pontoons for additional lateral stability, and
Amelia decided to design our own excavator
system. |

Since the Polly L's second launch in late 2000, the Polly
L's performance has exceeded all
expectations. She was on site more
than 200 days in 2001, which is unheard of in
this industry. Traditional salvage vessels
have a seasonal operating window, subject to
weather, of June thru September. Our lift
boat remains on site for extended periods of
time. We have no daily commuting to and
from the site, which saves valuable recovery
time.

The
working platform, raised above the ocean swells,
provides stable, comfortable accommodations for
the ship's crew, archaeological and media
consultants, and visitors. Dive teams can begin
dive operations at sunrise and continue until
sundown, working in rotating shifts after an excellent
night of rest and relaxation within the fully equipped
galley and staterooms.

The Polly L's on board systems set a new standard for
the industry. A ten
ton crane on the bow has more than adequate lifting
capacity for deeply lodged and heavy objects. We
can concurrently deploy the excavator, and dredge
through a sluice box, 24 hours a day. Our on board
facilities for preservation of recoveries are a first in
this industry. Extensive use of hydraulics results
in huge savings in fuel consumption. The Polly
L
burns 50 to 100 gallons of fuel in a 24 hour day, compared to the
voracious 50 to 80 gallons an hour appetite of
conventional salvage vessels. For more in-depth information about our lift boat technologies, click [here].
