About MarineWireCalc
Precision calculation tools engineered for boaters, anglers, and marine DIYers.
MarineWireCalc was founded by a team of marine electronics technicians and passionate anglers frustrated by confusing, ad-bloated calculation tools that fail to account for modern marine realities—especially the rapid adoption of Lithium (LiFePO4) batteries and high-thrust brushless trolling motors.
Our Engineering Standards
Every calculation tool hosted on MarineWireCalc strictly adheres to ABYC E-11 (AC and DC Electrical Systems on Boats) standards, published by the American Boat and Yacht Council.
- Critical Voltage Drop Limits: We calculate with a strict 3% voltage drop baseline for trolling motors, navigation, and critical marine electronics.
- Tinned Marine Copper Calculations: We use real-world resistance values ($K = 10.75$) corresponding to tinned stranded marine wire (BC-5W2), not generic household solid copper.
- Accurate Battery Chemistry Curves: We differentiate between 100% usable Depth of Discharge (LiFePO4) and the strict 50% cutoff required for Lead-Acid and AGM batteries.
Editorial Integrity & Independence
MarineWireCalc operates as an independent technical resource. While we may earn affiliate commissions on hardware recommendations (such as marine breakers and tinned cable), our calculation algorithms remain 100% objective and governed strictly by mathematical formulas and industry safety codes.
