Yacht electrical, energy and maintenance guides based on the experience we have gained on the water in Turgutreis and Bodrum.

On the Aslan Yacht blog we write up the experience we have gained on the water over the years around Turgutreis and the Bodrum peninsula. From switching to lithium batteries and connecting shore power to setting up NMEA 2000 networks, servicing Seakeeper stabilizers, flushing watermaker membranes and preparing a boat for winter, we cover the topics that motor and sailing yacht owners, captains and yacht managers actually run into.

In every article we put concrete technical information first: correct voltage values, cable sizing, fuse selection, maintenance intervals and fault symptoms. Our aim is to help owners understand their own systems better and ask the right questions when a service need comes up. We publish new articles regularly, under energy systems, electronics/navigation, lighting, stabilizers, hydraulics, watermakers and climate systems.

If you can't find the topic you're looking for, or you have a specific question about your own boat, write to us through our contact page or browse our full range of services.
