LiFePo4 batteries, Solar Hot Water,
Electric Propulsion


No product


We are experienced Mediterranean cruising sailors. The products that we sell are mostly in use on our own yacht. We have active experience not of every single variable, but of all the product lines - solar panels, controllers, batteries, solar hot water, and electric outboards.

Lithium Batteries

We are convinced that LifePo4 lithium batteries are now the right choice for all cruising yachts for their domestic use. They are cheaper, smaller, lighter, and offer 4 times more usable power than an AGM equivalent. Combined with a hybrid inverter, you can have almost unlimited electrical appliances and hot water.


For smaller batteries, we offer the Eco-Worthy range from China, and for 150A and more, our own systems that come from Renault and Nissan electric vehicles. By buying from us, you are buying "green" as well as inexpensive. We offer 12 and 48v units of 3 and 6Kw capacities. 

Hybrid Controllers

The latest hybrid controllers combine the functions of MPPT solar controller and 220v inverter. They range in power ratings from 1 to 5Kw depending on your 220v consumption needs and available solar power. In a single box you now have a multi-function MPPT solar controller that will decide from where to source power for your batteries (Lithium or AGM) while also providing 220v current for domestic use on board via the existing 220v circuit. We offer the excellent PowerMR range.

Solar Hot Water

Usually sailing yachts heat water from an engine heat exchanger or a 220v heating element when connected to shore power. If you run your engine seldom or not at all and are not fans of ports and marinas, that means cold water - not ideal for showers or washing the dishes.

We offer 12v, 48v and 220v solar hot water solutions for for most battery installations on yachts with Quick and Isotherm calorifiers. We use solar energy that would otherwise be discarded to turn on the water heater.

NEW! We can supply calorifiers that can have an engine heat exchanger, a 12v/300w heating element, and another that is 240v/1000w or any combination of those three. Offering much higher performance than that of the mainstream manufacturers, they are available in 25, 30, and 40 litre capacities. Apart from the improved water heating performance, the controller is cheaper because it is only monitoring battery voltage; The built-in thermostat controls the water temperature.

Electric Outboards

Our 5 to 20HP range of small electric outboards is very competitively priced, and the unit and battery are both very light, so easy to take on and off your tender.


We expect combustion engine powered tenders to come under increasing negative pressure in the immediate future. Two strokes are already banned in many places making electric a "must-have" that is silent, and costs nothing to run.

Electric Propulsion

Although we fully accept that electric propulsion is not viable for all sailors, technical progress means that for some cruising yachtsmen it is part of  a realistic and attractive option. Fitting an electric motor to drive your current propellor is easy and you can install a small genset in the space left by the old diesel engine.  We recommend at least 5Kw. Cost and weight of the complete system is way below that of a replacement diesel! The limiting factor is the autonomy that you seek.

Our inboard motors are made by China's leading manufacturer and the power range is from 5 to 35HP.
