Review of Ericson 37

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The interior is like many other boats made of mahogany.
The boat is equipped with a galley and toilet facility.

The boat 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 Ericson 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 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

Ericson 37 is typically equipped with an inboard Perkins 704 diesel engine.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Ericson 37 is 1.75, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Ericson 37 is about 255 kg/cm, alternatively 1432 lbs/inch.
Meaning: if you load 255 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1432 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Ericson 37 is 3.40.

Compared with other similar sailboats it is slimmer than 66% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

What is a Ballast Ratio?

The ballast ratio for Ericson 37 is 50%.

This ballast ratio shows a righting moment that is higher than 93% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

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): 15.45
