Review of Oceanis 38.1

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

The boat 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 genaker or a spinnaker for optimal speed.

The boat can only enter major marinas as the draft is about 2.08 - 2.18 meter (6.82 - 7.12 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard engine at 30.0 hp (22 kW), which gives a max speed about 6.2 knots.

The fuel tank has a capacity of 130.0 liters (34 US gallons, 28 imperial gallons).

If less than 10 in on board the boat is by European Union certified as Class C. INSHORE:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.9 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 Oceanis 38.1 is about 286 kg/cm, alternatively 1604 lbs/inch.
Meaning: if you load 286 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1604 lbs cargo on the boat it will sink 1 inch.

88% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 49m² (527 ft²).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
