A Northern Lights 18kw generator provides auxiliary power. The boat is fitted with an comprehensive Garmin electronics suite including dual GPS Map 8616 units, a GPS Map 8612, 24XD display, GXM 54 module, GHC 20 autopilot with Reactor 40 processor, GHP 30 hydraulic core pack, on-deck hub, GSD Chirp 26 sonar, GMR 424 open array radar, and dual GMI 20 instrument displays.

Custom modifications include a swim platform, custom rear door, specialized top deck layout, crane, and an integrated solar power grid—all designed to support extended cruising operations. The boat's systems and working components were consistently maintained throughout her service life to ensure reliability and availability.
