Hull

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

Interior

The boat is equipped with 206.0 liter fresh water capacity, toilet facility and 80.0 liter waste water capacity.

Keel

The Sun Odyssey 349 has been built with different keel alternatives.

L-shape fin keel

The Sun Odyssey 349 is equipped with a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.

The boat can only enter major marinas as the draft is about 1.98 - 2.08 meter (6.50 - 6.80 ft) dependent on the load. See immersion rate below.

Unknown keel type

Sun Odyssey 349 can enter even shallow marinas as the draft is just about 1.49 - 1.59 meter (4.89 - 5.19 ft) dependent on the load. See immersion rate below.

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 1.26 - 1.36 meter (4.13 - 4.43 ft) dependent on the load. See immersion rate below.

Engine

The boat may be equipped with an inboard Yanmar 3YM20 diesel engine at 21 hp (15 kW). Calculated max speed is about 5.5 knots

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

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sun Odyssey 349 is 1.98, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

EU classification

Sun Odyssey 349 holds two CE certifications:

If less than 6 in on board the boat is by European Union certified as Class A. OCEAN:

Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.

If less than 8 in on board the boat is by European Union certified as Class B. OFFSHORE:

Designed for offshore voyages where conditions up to, and including, wind force 8 (Beaufort scale) and significant wave heights up to, and including, 4 m may be experienced.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.4 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Sun Odyssey 349 is about 216 kg/cm, alternatively 1213 lbs/inch.
Meaning: if you load 216 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1213 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Sun Odyssey 349 is 22.8.

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.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Sun Odyssey 349 is 2.90.

Compared with other similar sailboats it is more spacy than 76% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Sun Odyssey 349 is 30%.

This ballast ratio shows a righting moment that is higher than 8% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly below average.

D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Sun Odyssey 349 is 179 which categorizes this boat among 'light racers'.

79% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

SA/D (Sail Area Displacement ratio)

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

The SA/D for Sun Odyssey 349 with ISO 8666 reference sail is 16.9, with a 135% genua the SA/D is 19.8.

The SA/D ratio indicates that it is faster than 54% of all similar sailboat designs in light wind.

Over- / underrigged

The Sun Odyssey 349 has more rig than 79% of all similar sailboats, which indicates that the boat is significantly overrigged.

Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 38m² (409 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.
