The client
VIGOR Alaska operates the Ketchikan Shipyard offering top-notch and expanding facilities in southeastern Alaska along the the Inland Passage.
The brief
CMDL partnered with ASD to provide a design-build contract for the provision of a 23-car, 149-passenger, sheltered water ferry for the State of Alaska, for service to the Ketchikan Airport. CMDL provided the contract design package as well as full CAD production model and drawings. CMDL also provided project management assistance on site at the shipyard.
The design
The 116.5 foot ferry accommodates 149 persons, and either 23 cars, or two large semi‐tractor/trailers and 8 cars.
The simple double-ended hull is fitted with one skeg at each end to increase directional stability and house the shafts, one at each end. Power is provided by two Cummins KTA 38 MO Tier-2 compliant rated at 850 bhp each.
Ship Service Power Generation is provided by two Northern Light M55C2 Tier 2 engine/generator sets.
The off‐centreline starboard side deckhouse allows for ready loading and unloading of large trucks. The vessel incorporates a number of special structural, mechanical and control features in order to meet the Owner’s manning requirement of just two crew members. The ferry was designed and built under US Coast Guard and the American Bureau of Shipping.
