Review of Wasa 37

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The deck is a double deck which improves the indoor climate.

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 3 cabins, 6 berths, 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 boat is typically equipped with an inboard Volvo Penta 2002 diesel engine at 18.0 hp (13 kW), which gives a max speed about 5.4 knots.

The transmission is a saildrive.

The fuel tank which is made of stainless steel has a capacity of 90 liters (23 US gallons, 19 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Wasa 37 is 1.92, 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 7.2 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 Wasa 37 is about 184 kg/cm, alternatively 1034 lbs/inch.
Meaning: if you load 184 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1034 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Wasa 37 is 21.8.

Comparing this ratio with similar sailboats show that it is more comfortable than 21% of all similar sailboat designs. This is a comfort value significantly below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Wasa 37 is 3.56.

Compared with other similar sailboats it is slimmer than 85% of all other designs. It seems that the designer has chosen a significantly more speedy hull design.

What is Displacement Length Ratio?

The DL-ratio for Wasa 37 is 187 which categorizes this boat among 'light racers'.

79% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

What is Relative Speed Performance?

The Relative Speed Performance for Wasa 37 is 73

The relative speed performance is 73 which means that a it is faster than 73% of all similar sailboat designs.
