Review of Oceanis 30.1

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, a galley and toilet facility.

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 Oceanis 30.1 has been built with more than one type of keel.

One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

Another option is a L keel. The keel is an L-shape and therefore less exposed to seaweed, fishing nets and lines.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can only enter major marinas as the draft is about 1.88 - 1.98 meter (6.17 - 6.47 ft) dependent on the load. See immersion rate below.

Oceanis 30.1 is typically equipped with an inboard engine at 15.0 hp (11 kW), which gives a max speed about 5.2 knots.

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

What is Capsize Screening Formula (CSF)?

The capsize screening value for Oceanis 30.1 is 1.90, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Oceanis 30.1 holds three CE certifications:

If less than 6 in on board the boat is by European Union certified as Class B. OFFSHORE:
If less than 8 in on board the boat is by European Union certified as Class C. INSHORE:
If less than 10 in on board the boat is by European Union certified as Class D. SHELTERED WATERS:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 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 30.1 is about 173 kg/cm, alternatively 970 lbs/inch.
Meaning: if you load 173 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 970 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Oceanis 30.1 is 22.5.

Comparing this ratio with similar sailboats show that it is more comfortable than 46% of all similar sailboat designs. This comfort value is just below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Oceanis 30.1 is 3.01.

Compared with other similar sailboats it is more spacy than 58% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is Displacement Length Ratio?

The DL-ratio for Oceanis 30.1 is 172 which categorizes this boat among 'light racers'.

86% 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 32m² (344 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
