Review of Apocalypse 13 Régate

The boat is equipped with 3 cabins and 8 berths.

The boat 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.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

The boat can only enter major marinas as the draft is about 1.90 - 2.00 meter (6.23 - 6.53 ft) dependent on the load. See immersion rate below.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Apocalypse 13 Régate is 1.89, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Apocalypse 13 Régate holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 8.3 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 Apocalypse 13 Régate is about 249 kg/cm, alternatively 1398 lbs/inch.
Meaning: if you load 249 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1398 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Apocalypse 13 Régate is 18.2.

Comparing this ratio with similar sailboats show that it is more comfortable than 5% 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 Apocalypse 13 Régate is 3.99.

Compared with other similar sailboats it is slimmer than 97% 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 Apocalypse 13 Régate is 40%.

This ballast ratio shows a righting moment that is higher than 54% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.

What is Displacement Length Ratio?

The DL-ratio for Apocalypse 13 Régate is 81 which categorizes this boat among 'ultra light racers'.

98% 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 Apocalypse 13 Régate with ISO 8666 reference sail is 24.3, with a 135% genua the SA/D is 29.1.

The SA/D ratio indicates that it is faster than 100% of all similar sailboat designs in light wind.

The Apocalypse 13 Régate has more rig than 100% of all similar sailboats, which indicates that the boat is significantly overrigged.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 45m² (484 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.
