Review of Bayfield 25

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 of Bayfield 25 anno 1988.

The boat is equipped with 45.0 liter fresh water capacity.

The Bayfield 25 is 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.

Full keel

The Bayfield 25 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 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 even shallow marinas as the draft is just about 0.89 - 0.99 meter (2.92 - 3.22 ft) dependent on the load. See immersion rate below.

Bayfield 25 may be equipped with a Petter diesel engine.

The fuel tank has a capacity of 45.0 liters (11 US gallons, 9 imperial gallons).

What is Capsize Screening Formula (CSF)?

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.9 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 Bayfield 25 is about 98 kg/cm, alternatively 549 lbs/inch.
Meaning: if you load 98 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 549 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

The l/b ratio for Bayfield 25 is 3.12.

What is a Ballast Ratio?

What is Displacement Length Ratio?

The DL-ratio for Bayfield 25 is 205 which categorizes this boat among 'light crusers & offshore racers'.

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

The SA/D for Bayfield 25 with ISO 8666 reference sail is 20.0, with a 135% genua the SA/D is 24.0.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 15m² (161 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.
