Hull

The hull is made of fibreglass. 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.


Rig

The Puma 27 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.


Keel

Unknown keel type

The boat can enter most marinas as the draft is just about 1.56 - 1.66 meter (5.12 - 5.42 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Puma 27 is about 150 kg/cm, alternatively 842 lbs/inch.
Meaning: if you load 150 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 842 lbs cargo on the boat it will sink 1 inch.
