15-Vehicle Electric Ferry
VESSEL DESCRIPTION
This 120' monohull vessel is intended to provide vehicle and passenger transportation between Skagway and
Haines. The vessel is intended to be all-electric. The vessel will utilize a lithium-ion battery bank charged by shore
power. The estimated contract design cost is $400 -$500 thousand, with construction cost approximately $7-$8
million, not including any shoreside infrastructure changes for charging.
