Review of Targa 42

The Targa 42 is 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 gennaker or a spinnaker for optimal speed.

Unknown keel type

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 most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

The boat may be equipped with dual inboard Volvo Penta engines at 370 hp (275 kW). The speed is 37.0 knots.

The transmission is a Z-drive aka sterndrive.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Targa 42 is 1.73, 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 7.3 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 Targa 42 is about 174 kg/cm, alternatively 979 lbs/inch.
Meaning: if you load 174 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 979 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Targa 42 is 24.5.

Comparing this ratio with similar sailboats show that it is more comfortable than 24% of all similar sailboat designs. This is a comfort value significantly below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Targa 42 is 4.29.

Compared with other similar sailboats it is slimmer than 100% of all other designs. It seems that the designer has chosen a significantly more speedy hull design. This type of design is also referred to as 'needle'.

What is a Ballast Ratio?

The ballast ratio for Targa 42 is 46%.

This ballast ratio shows a righting moment that is higher than 85% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

What is Displacement Length Ratio?

The DL-ratio for Targa 42 is 183 which categorizes this boat among 'light racers'.

79% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

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

The SA/D for Targa 42 with ISO 8666 reference sail is 19.8, with a 135% genua the SA/D is 22.8.

The SA/D ratio indicates that it is faster than 79% of all similar sailboat designs in light wind.

The Targa 42 has more rig than 95% of all similar sailboats, which indicates that the boat is significantly overrigged.

What is Relative Speed Performance?

The Relative Speed Performance for Targa 42 is 54

The relative speed performance is 54 which means that a it is faster than 54% of all similar sailboat designs.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 31m² (333 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.
