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 6 berths and 250.0 liter fresh water capacity.
The Najad 355 is equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.
Fin keel
The Najad 355 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Najad 355 is 1.80, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Najad 355 holds a CE certification:
The boat is by European Union certified as Class A. OCEAN:The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Najad 355 is about 248 kg/cm, alternatively 1390 lbs/inch.
Meaning: if you load 248 kg cargo on the boat then it will sink 1 cm.
