Winter Yacht Maintenance – Our Recommended List Of Works

Winter Yacht MaintenanceWe feel it is essential to carry out a schedule of preventative maintenance and protect your vessel from deteriorating over the winter.

It is all to easy to forget you have a yacht only to find in the spring that the boat and sails are covered in green algae and equipment ceases to work.
