Looking for a new boat? Find a Hylas 51 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 Hylas 51 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.
The Hylas 51 has been built with different keel alternatives.
Unknown keel type
The boat can only enter major marinas as the draft is about 2.60 - 2.70 meter (8.53 - 8.83 ft) dependent on the load. See immersion rate below.
Fin keel
The Hylas 51 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 1.98 - 2.08 meter (6.50 - 6.80 ft) dependent on the load. See immersion rate below.
Hylas 51 may be equipped with an inboard Yanmar diesel engine
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 Hylas 51 is about 488 kg/cm, alternatively 2735 lbs/inch.
Meaning: if you load 488 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2735 lbs cargo on the boat it will sink 1 inch.
