Rig

The Breehorn 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.


Keel

The Breehorn 37 has been built with different keel alternatives.

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 1.40 - 1.50 meter (4.59 - 4.89 ft) dependent on the load. See immersion rate below.

Unknown keel type

The boat can only enter major marinas as the draft is about 1.90 - 2.00 meter (6.23 - 6.53 ft) dependent on the load. See immersion rate below.


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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Breehorn 37 is about 267 kg/cm, alternatively 1496 lbs/inch.
Meaning: if you load 267 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1496 lbs cargo on the boat it will sink 1 inch.
