Review of Catalina 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.

The Catalina 25 has been built with different keel alternatives.

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 0.61 - 0.71 meter (2.00 - 2.30 ft) dependent on the load. See immersion rate below.

Wing keel

But be aware that even though a Wing Keel keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

The boat can enter even shallow marinas as the draft is just about 0.86 - 0.96 meter (2.82 - 3.12 ft) dependent on the load. See immersion rate below.

Fin 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 full keel.

Catalina 25 can enter even shallow marinas as the draft is just about 1.22 - 1.32 meter (4.00 - 4.30 ft) dependent on the load. See immersion rate below.

An outboard motor is often used on this boat. In that case the boat will typically require a power of 4 - 5 hp, alternatively 91 - 109 lbs thrust if you prefer an electrical motor. Electric outboards are becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Catalina 25 is 1.93, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.3 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 Catalina 25 is about 110 kg/cm, alternatively 617 lbs/inch.
Meaning: if you load 110 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 617 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Catalina 25 is 19.0.

What is L/B (Length Beam Ratio)?

The l/b ratio for Catalina 25 is 3.12.

What is a Ballast Ratio?

The ballast ratio for Catalina 25 is 36%.

What is Displacement Length Ratio?

The DL-ratio for Catalina 25 is 187 which categorizes this boat among 'light racers'.

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

The SA/D for Catalina 25 with ISO 8666 reference sail is 15.7, with a 135% genua the SA/D is 18.8.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 20m² (215 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.
