HOW IT WORKS

Design your system in 3 steps

From energy needs to full system design in minutes — see exactly what fits, what it costs, and how much power you'll generate.

1

Energy Calculator

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

2

System Planner

Pick your equipment — solar panels, batteries, wind generator, watermaker. Each item drops onto the boat diagram automatically with live power and cost calculations.

3

Save & Track

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

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.

Trusted by
bluewater sailors.

Vindhav was built because we couldn't find a single place that understood both the engineering and the sailing life. Every product is tested offshore.
