Review of Granada 23

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.

The boat is equipped with one cabin, 4 berths and a galley.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

The Granada 23 has been built with more than one type of keel.

One option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

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.

An outboard motor is often used on this boat. In that case Granada 23 will typically require a power of 3 - 4 hp, alternatively 75 - 90 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 Granada 23 is 1.94, 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 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 Granada 23 is about 92 kg/cm, alternatively 517 lbs/inch.
Meaning: if you load 92 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 517 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Granada 23 is 18.8.

Comparing this ratio with similar sailboats show that it is more comfortable than 76% of all similar sailboat designs. This is a comfort value significantly above average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Granada 23 is 3.05.

Compared with other similar sailboats it is slimmer than 66% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

What is Displacement Length Ratio?

The DL-ratio for Granada 23 is 219 which categorizes this boat among 'light crusers & offshore racers'.

42% 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.

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

The SA/D for Granada 23 with ISO 8666 reference sail is 17.5, with a 135% genua the SA/D is 20.2.

The SA/D ratio indicates that it is faster than 46% of all similar sailboat designs in light wind.

What is Relative Speed Performance?

The Relative Speed Performance for Granada 23 is 69

The relative speed performance is 69 which means that a it is faster than 69% of all similar sailboat designs.
