The hull is made of fibreglass while the deck is made of wood. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
The Mariner 32 is equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.
Full keel
The Mariner 32 is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
The boat can enter even shallow marinas as the draft is just about 1.12 - 1.22 meter (3.67 - 3.97 ft) dependent on the load. See immersion rate below.
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Mariner 32 is 1.68, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.8 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Mariner 32 is about 155 kg/cm, alternatively 871 lbs/inch.
Meaning: if you load 155 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 871 lbs cargo on the boat it will sink 1 inch.

The l/b ratio for Mariner 32 is 3.27.
The ballast ratio for Mariner 32 is 40%.
What is Displacement Length Ratio?
The DL-ratio for Mariner 32 is 327 which categorizes this boat among 'heavy cruisers'.
What is SA/D (Sail Area Displacement ratio)?
The SA/D for Mariner 32 with ISO 8666 reference sail is 12.2, with a 135% genua the SA/D is 14.6.
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 24m2 (258 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.
Note: If you use a paint roller you will need more paint than if you use a paintbrush.
