Vessel Overview

65-ft steel motorsailer, research vessel

The Iron Lady, a 65-ft steel motorsailer, originally built in 1989, has been extensively customized for marine charters and long-range expeditions. Operating in remote and often harsh environments, the vessel is designed for self-sufficiency. It carries 1,800 gallons of diesel and 500 gallons of fresh water and is equipped with a watermaker, heater, refrigeration, and extensive onboard accommodations for up to 12 people.

With a robust sailing rig consisting of a genoa, staysail, and mainsail, the vessel is optimized for efficiency and reliability in demanding conditions.


Mission & Operations

This vessel is primarily engaged in marine biology research projects across the North Pacific, from Japan to the Bering Strait, with an active season from April to November. The research teams onboard work under strict schedules, completing tasks such as:

  • Steller sea lion surveys in the Western Pacific.
  • Support vessel to catch seals and temporarily instrument them with satellite transmitters to study migrations.
  • Collect whale photo IDs and biopsy samples for population studies.

Given the unpredictable nature of the North Pacific, the vessel routinely operates in challenging weather conditions, requiring equipment that can perform consistently in high-stress environments.

Over the past five years of rigorous use, the PSS system has proven to be reliable, easy to maintain, and simple to troubleshoot—critical factors for a vessel that must remain operational far from port.
