Yacht energy storage

Is energy storage a new direction for superyacht propulsion?

Recent high profile launches have made much of their energy storage capabilities, with Feadship’s Savannah being a classic recent example. Carrying something close to one megawatt of battery power, it heralds a new direction for superyacht propulsion, although the basic idea of energy storage on board has been around for a while.

Can a house battery be used on a sailing yacht?

Storing energy allows you to live of shorepower at sea or lets you use solar power harvested during the day over night. The inverter will convert the stored power to 230V. Sailing yachts typically experience long intervals between battery recharges, so your house battery should have a generous capacity.

How much electricity does a sailing yacht use?

A modern sailing yacht is packed with a lot of electrical equipment. Most things used to run the boat usually use DC, bigger (household) appliances need AC. When it comes to estimating power consumption, many just add up the Watts. Time is equally important. A microwave might use 1000 Watts, but only for 2 minutes.

How often should a yacht battery be recharged?

Sailing yachts typically experience long intervals between battery recharges, so your house battery should have a generous capacity. As a rule of thumb, we’re calculating with 48 hrs on board without shore power shore/engine/generator/solar power. Multiply the daily power consumption x days for even greater independency.

How much energy does a solar-powered Baltic yacht produce?

The 60 square meters of solar panels produces 30-50 kWh of energy per day, enough to power all of the onboard electronic equipment for around seven hours. Solar-powered Baltic yacht.

How will technology affect a yacht?

Technology will continue to make yachts ever simpler to operate. The ability to go daysailing easily will be critical for an increasingly time-poor generation, while powerboaters drawn to the eco credentials of sailing will seek an intuitive format, in yachts that are easy to rig, dock and manage.
