Looking for a new boat? Find a Puma 37 or similar boat for sale
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The Puma 37 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
Fin keel
The Puma 37 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
The boat can enter most marinas as the draft is just about 1.60 - 1.70 meter (5.25 - 5.55 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Puma 37 is about 277 kg/cm, alternatively 1554 lbs/inch.
Meaning: if you load 277 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1554 lbs cargo on the boat it will sink 1 inch.
