Review of Eol 30

Both the hull and the deck 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.
Unfortunately, the hull is not a double hull which affects the indoor climate. Especially if the water is considerable colder than the cabin, then one might expect condense water in the cabin.
The deck is a double deck which improves the indoor climate.

The boat is equipped with one cabin, 6 berths, a galley and toilet facility.
The headroom is above average

The boat 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.

The Eol 30 is equipped with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.

Eol 30 is typically equipped with an inboard Yanmar YSB 8 diesel engine at 8.0 hp (5 kW), which gives a max speed about 4.0 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of has a capacity of 50.0 liters (13 US gallons, 10 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Eol 30 is 2.16, indicating that this boat would not be accepted to participate in ocean races.

Eol 30 holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.7 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 Eol 30 is about 162 kg/cm, alternatively 910 lbs/inch.
Meaning: if you load 162 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 910 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Eol 30 is 18.7.

Comparing this ratio with similar sailboats show that it is more comfortable than 38% of all similar sailboat designs. This comfort value is just below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Eol 30 is 2.60.

Compared with other similar sailboats it is more spacy than 93% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Eol 30 is 40%.

This ballast ratio shows a righting moment that is higher than 50% of all similar sailboat designs. This righting moment (ability to resist heeling) is spot on average!

What is Displacement Length Ratio?

The DL-ratio for Eol 30 is 195 which categorizes this boat among 'light racers'.

69% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Eol 30 with ISO 8666 reference sail is 14.4, with a 135% genua the SA/D is 17.5.

The SA/D ratio indicates that it is faster than 31% of all similar sailboat designs in light wind.
It is expected that motor sailers has a low SA/D value as this is the natural consequence of combining sailing and motor characteristics.

The Eol 30 has more rig than 54% of all similar sailboats, which indicates that the boat is slightly overrigged.

What is Relative Speed Performance?

The Relative Speed Performance for Eol 30 is 24

The relative speed performance is 24 which means that a it is faster than 24% of all similar sailboat designs. As this boat is a motor sailer, it is expected that the performance of a motor sailer for sail alone is lower than a dedicated sailboat.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 18m² (193 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.
