How it works

From energy needs to a finished system in minutes.

See exactly what fits your vessel, what it costs, and how much power you'll generate — before anything ships.

01

Energy Calculator

Choose your vessel, then dial in daily loads — fridge, autopilot, lights, electronics. Toggle anchor vs. underway to see exact amp-hours needed.

→ Live amp-hour modelling
02

System Planner

Pick your equipment. Each item drops onto the boat diagram automatically with live power and cost calculations as you build.

→ Visual one-cart checkout
03

Save & Track

Save to your Vessel Dashboard. Track maintenance schedules, log service dates, and monitor equipment health in one place.

→ Lifetime vessel record

"We ran the Leopard 45 configurator, ordered everything in one cart, and had a certified installer quote within 48 hours. The power calculator alone saved us from under-speccing our battery bank by 200Ah."
