P/V Enforcer Completes Sponson and Exhaust Stack Additions

02-26-2008 Coastwise Corporation recently completed the design and construction support of sponson and exhaust stack additions to the Patrol Vessel Enforcer. The 79 foot long P/V Enforcer is a fish and wildlife protection vessel owned by the State of Alaska. The vessel operates year-round in Alaska enforcing fish and game management and providing search and rescue capability.

Coastwise's design added three foot wide sponsons to increase the vessel's beam to 27 feet in order to improve stability. Significant effort was expended to design the full-length sponsons with a minimum of hydrodynamic resistance and wave slamming potential. Large bilge keels were also removed as a part of this modification. Exhaust stacks and all new dry-exhaust systems were added to the Enforcer to improve skiff handling operations alongside the vessel and to increase space in the engine room.

These modifications were completed at Everett Shipyard in Everett, WA and the Enforcer was sea trialed and tested for stability. The vessel's lightship intact stability was improved by over 600% and operational speed was increased by 0.5 knots. The operators also commented on the reduction of exhaust noise in the wheelhouse.

The P/V Enforcer returned to active duty with no operational restrictions and recently completed a successful patrol of the Sitka Sound herring fishery. For more information contact Coastwise Corporation.
