The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.


The boat is equipped with one cabin, 4 berths, 75.0 liter fresh water capacity and toilet facility.


The boat is typically equipped with an inboard Yanmar diesel engine at 100.0 hp (74 kW).

The fuel tank has a capacity of 200.0 liters (52 US gallons, 43 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for ACM Héritage 26 is about 138 kg/cm, alternatively 776 lbs/inch.
Meaning: if you load 138 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 776 lbs cargo on the boat it will sink 1 inch.
