Solar Array Design
Panel selection, mounting layout, charge controller sizing, wiring specifications, and integration with existing battery and charging systems.
AC/DC Distribution Design
Panel layouts, circuit protection, wire sizing, load calculations, and distribution diagrams for both AC shore power and DC house systems.
Complete Rewire Planning
Full vessel electrical redesign for aging boats or major retrofits. New panel design, wire run planning, component specification, and phased implementation plans.
Navigation System Integration
Chartplotter, radar, AIS, autopilot, and instrument networking design. NMEA 2000 backbone layout and power distribution for electronics.
LED Lighting Design

Real projects completed by Accumar Marine. Every design follows ABYC standards and is tailored to the vessel, the owner's budget, and their cruising plans.
42' Sportfish
Complete Electrical Refit
Full DC System Redesign with Lithium Conversion
Owner wanted to eliminate generator dependency at anchor. We designed a complete DC system overhaul: replaced the aging AGM bank with 600Ah LiFePO4, added 800W solar with MPPT controllers, redesigned the DC distribution panel with proper fusing per ABYC E-11, and integrated a 3,000W inverter/charger. The boat now runs AC, refrigeration, and electronics for 48+ hours at anchor without a generator.

Offshore Passage Prep
Navigation & Electrical Systems for Caribbean Crossing
Owners were preparing for their first offshore passage from Fort Myers to the Bahamas and beyond. We designed a redundant navigation system with dual chartplotters, AIS transceiver, SSB/HF radio, and satellite communication. Rebuilt the NMEA 2000 backbone, added a dedicated electronics panel with proper circuit protection, and installed a battery monitoring system so they could track consumption underway. Remote consultation followed up during their first 30 days of cruising.

Result
Safe offshore passage
65' Motor Yacht
AC System Redesign
Shore Power & HVAC Load Balancing for Multi-Zone Cooling
This yacht had chronic breaker trips when running AC at the dock. The original wiring had 4 marine AC units on a single 50A shore power leg with no load management. We redesigned the AC distribution with proper load balancing across both legs of 50A service, added soft-start modules to each compressor to reduce inrush current, and installed a shore power management system that sequences compressor starts. The owner went from constant breaker trips to running all 4 zones simultaneously without issues.

Result
Zero breaker trips

Remote Consultation
Remote Battery Bank Design for DIY Owner in Chesapeake Bay
Owner in Maryland wanted to upgrade from a failing AGM house bank to lithium but couldn't find a qualified marine electrician locally. Through a series of video consultations, we assessed his current system via photos and documentation, designed a drop-in 400Ah LiFePO4 bank with proper BMS, verified his existing chargers were compatible, and provided detailed wiring diagrams with step-by-step installation notes. The owner completed the installation himself over a weekend and has been cruising the Chesapeake trouble-free since.
