With South Africa experiencing soaring temperatures at high summer, boat owners are feeling the heat – and we’re here to help.   

At Southern Power, our vision is to be a leader in delivering pioneering technologies for marine propulsion, electricity generation and heating/cooling that also contribute to reducing environmental impact, in our chosen market segment of Southern Africa.

With this in mind, and summer upon us, here are a few innovative cooling solutions for you from our various OEMs, for marine applications.

Marine vessel interiors

On the open water, where the harsh summer sun reflects off the ocean’s surface, boat cabins can become unbearably hot. Ensure that your cabins stay comfortably cool with one of Webasto’s self-contained air-conditioning or chiller systems.

Southern Power can equip you with Webasto systems providing cooling capacities from        5 000 BTU/h up to 1 500 000 BTU/h, depending on the size of your boat. You can equip each cabin with its own super-quiet, fully adjustable cooling unit.

For mid-size boats including yachts, the Webasto Marine BlueCool Premium is the ideal system, using a sea water cooling circuit and dual air handles to generate a flow of cool air into your boat’s interior.

Let in the light without the heat

Designed to adapt to boats of all kinds, Webasto manufactures high-quality shading and roof systems, to provide passengers with the best possible comfort on board. These are easy to install and robust. Webasto’s 20-, 60-, 80- and 100-Series marine sliding roofs and platforms are depended on by boat builders and owners worldwide, to provide additional light and aeration to boat interiors, while fending off the heat.

Don’t forget about your engines


As a boat owner, protect your boat’s engines against the summer heat and saltwater with Volvo Penta coolants – tailor-made for your engine to prevent overheating in summer, while providing maximum component protection for both older and newer engines.

Marine coolants like these are less harmful to the environment than auto antifreeze, as they use propylene glycol and not ethylene glycol, which is extremely toxic to the environment. 

The benefits for your engines: optimal antifreeze protection and thermal transfer capacity; high boiling point to prevent overheating; maximum protection against corrosion, cavitation,ageing, swelling and cracking; powerful additives to prolong engine life; no deposits in the cooling system; convenient two-year change interval.

Recycle greywater and produce fresh water onboard

Still on engine protection, it’s important to ensure that your greywater system is addressed. FCI watermakers’ world-class system design optimises the flow of water, while industrial-quality materials employed throughout the reverse osmosis system ensure robust operations. 

For boat passengers, an FCI watermaker will ensure that no one goes thirsty on those sun-baked days out on the sea. https://www.southernpower.co.za/fci-watermakers/
