The Union Leader reported that security at the Port of New Hampshire is expected to be enhanced by the acquisition of a boat, which would be used to fight maritime fires and help in other water-based emergencies. The information was offered yesterday to members of the of the Pease Development Authority's Division of Ports and Harbors Port Use Ad Hoc Committee. Portsmouth Assistant Fire Chief Steve Achilles told the committee, chaired by State Sen. Martha Fuller Clark, the vessel is expected to be ready by the fall of next year. The fire official said he hopes the vessel can be based at the state-run port on Market Street, since the location provides the best possible access to the Piscataqua River.
