Portside Marine & Towing, Inc.

Portside Marine & Towing, Inc., a for-profit maritime services firm based in Pensacola, Florida, operates exclusively as a prime contractor providing tug services, harbor docking assistance, and navigational support to the U.S. Coast Guard and Military Sealift Command, competing full-and-open without set-aside designation across most of its footprint, though it qualifies for and has received Total Small Business set-aside awards.

The vendor's entire federal customer base consists of two agencies. The Department of Homeland Security's U.S. Coast Guard accounts for 56 of 57 total awards (100% coverage by award count and dollar value) representing $636 thousand in combined potential value, with the Department of the Navy's Military Sealift Command placing one award for $43,950 in March 2026 for tug services at the Port of Pensacola for USNS Point Loma. This extreme customer concentration reflects Portside's geographic and operational lock on tug service delivery at Naval Air Station Pensacola and the surrounding maritime environment, where it supports routine harbor operations—getting Coast Guard cutters underway, assisting with mooring and unmooring, conducting shakedown cruises, and emergency response—for homeported vessels including USCGC Diligence, USCGC Reliance, and USCGC Walnut.

Recent representative work includes a $25,150.50 Total Small Business purchase order from Coast Guard dated September 8, 2026, for CGC Diligence shakedown tug services; an $8,607.06 Total Small Business award dated September 16, 2026, for CGC Diligence patrol tug services; an $8,316 full-and-open purchase order dated September 10, 2026, for harbor docking service at Pensacola Naval Air Station; and a $15,000 full-and-open award dated July 30, 2026, for tug services and mooring assistance from NAS Pier. NAICS coding concentrates under 488330 (Navigational Services to Shipping, 36 awards) and 488320 (Port and Harbor Operations, 15 awards), with PSC categories dominated by vessel towing and husbanding services.

Activity declined sharply from eleven awards in 2022 to a single award in 2025, with six awards in 2026 year-to-date as of the October 15, 2026, snapshot. Combined potential value sits at $680 thousand with $665 thousand obligated (98%), indicating nearly full draw-down of contract ceilings. The vendor holds no parent contract vehicles and operates entirely on discrete purchase orders, each firm fixed price, each short-duration (ultimate completion dates typically within weeks of award). No subcontract relationships appear in the source data; Portside operates as a 100% prime, with zero sub-award activity.
