The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 492.0 liter fresh water capacity.
The Reliance 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 Reliance 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 only enter major marinas as the draft is about 1.91 - 2.01 meter (6.27 - 6.57 ft) dependent on the load. See immersion rate below.
Reliance 37 may be equipped with an inboard Volvo Penta MD11 diesel engine at 25 hp (18 kW). Calculated max speed is about 5.0 knots
The fuel tank has a capacity of 265.0 liters (70 US gallons, 58 imperial gallons).
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 Reliance 37 is 1.75, 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 7.5 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 Reliance 37 is about 218 kg/cm, alternatively 1223 lbs/inch.
Meaning: if you load 218 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1223 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 38m2 (409 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.
