Hull

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.

Interior

The boat is equipped with 75.0 liter fresh water capacity.

Keel

Full keel

The Bayfield 29 is equipped with a long keel. A full 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 boat can enter even shallow marinas as the draft is just about 1.07 - 1.17 meter (3.51 - 3.81 ft) dependent on the load. See immersion rate below.

Engine

Bayfield 29 may be equipped with an inboard Yanmar 2GM diesel engine at 15 hp (11 kW). Calculated max speed is about 5.0 knots

The fuel tank has a capacity of 75.0 liters (19 US gallons, 16 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 Bayfield 29 is 2.12, indicating that this boat would not be accepted to participate in ocean races.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.2 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 Bayfield 29 is about 137 kg/cm, alternatively 771 lbs/inch.
Meaning: if you load 137 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 771 lbs cargo on the boat it will sink 1 inch.

Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Bayfield 29 is 42%.

This ballast ratio shows a righting moment that is higher than 58% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.

D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Bayfield 29 is 307 which categorizes this boat among 'medium weight cruisers'.

27% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.

SA/D (Sail Area Displacement ratio)

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

The SA/D for Bayfield 29 with ISO 8666 reference sail is 18.2, with a 135% genua the SA/D is 22.0.

The SA/D ratio indicates that it is faster than 76% of all similar sailboat designs in light wind.

Over- / underrigged

The Bayfield 29 has more rig than 100% 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 21m² (226 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.
