MARINER Yachts Mariner 31

Mariner 31

Two varieties of comfort

Our flagship model, depending on equipment and furnishing, is either a big, comfortable inland M31-8sailboat or a typical sea yacht. The inland version is equipped with a centerboard and an internal bottom balast, a tiller and an engine fixed on transom. Of course on request we can change the tiller to  a steering wheel and fix a Disel sterndrive. The next step can be changing the centerboard and the balast to a keel which transforms the boat  into a sea yacht.
Regardless of the version Mariner 31 has a spacious and fully adaptable interior.
The aft bed can be lengthwise or transverse the interior, separated from the  saloon or not. In the forward there can be a cabin with a floor or a separated forward bed. It can suit everybody’s taste. The interior can accommodate even 8 crew members,and the galley can be equipped with a cooker, sink and fridge. SONY DSC
The deck of the yacht designed in a characteristic style is similar to the best yachts in this category.An ample number of windows makes the interior bright and well ventilated.
On request the yacht can be equipped with the main sail and jib furling system, electrical system of raising and folding the mast and the centerboard and other facilities which make using the yacht easier. The self-bailing cockpit is closed with a plank in the version equipped with a tiller and with a laminated seat in the version with a steering wheel.
Teak finishings in the cickpit add to the elegance of the yacht. A modern shape of the hull and rigging guarantee above average sailing performance.
