Review of Crealock 37

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 360.0 liter fresh water capacity.

The boat has more than one rig.

One option is 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.

Another option is a yawl rig. A yawl 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 yawl allows for better comfort and stability when sailing downwind or on a broad reach.

Full keel

The Crealock 37 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 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.

Crealock 37 can enter most marinas as the draft is just about 1.62 - 1.72 meter (5.31 - 5.61 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta diesel engine

The fuel tank has a capacity of 151.0 liters (39 US gallons, 33 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Crealock 37 is 1.72, 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 7.1 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 Crealock 37 is about 187 kg/cm, alternatively 1047 lbs/inch.
Meaning: if you load 187 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1047 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Crealock 37 is 33.7.

What is L/B (Length Beam Ratio)?

The l/b ratio for Crealock 37 is 3.41.

What is a Ballast Ratio?

The ballast ratio for Crealock 37 is 39%.

What is Displacement Length Ratio?

The DL-ratio for Crealock 37 is 334 which categorizes this boat among 'heavy cruisers'.

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 15.95

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 31m² (333 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
