Review of Trident 24

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 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 boat is typically equipped with an inboard Vire gasoline engine at 7.0 hp (5 kW), which gives a max speed about 4.3 knots.

The fuel tank has a capacity of 45 liters (11 US gallons, 9 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Trident 24 is 1.86, 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 5.8 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 Trident 24 is about 87 kg/cm, alternatively 490 lbs/inch.
Meaning: if you load 87 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 490 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Trident 24 is 21.0.

Comparing this ratio with similar sailboats show that it is more comfortable than 79% 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 Trident 24 is 3.24.

Compared with other similar sailboats it is slimmer than 85% of all other designs. It seems that the designer has chosen a significantly more speedy hull design.

What is Displacement Length Ratio?

The DL-ratio for Trident 24 is 263 which categorizes this boat among 'light crusers & offshore racers'.

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.

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

The SA/D for Trident 24 with ISO 8666 reference sail is 16.4, with a 135% genua the SA/D is 18.8.

The SA/D ratio indicates that it is faster than 42% of all similar sailboat designs in light wind.
