Review of Avance 36

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.
The deck is a double deck which improves the indoor climate.

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 6 berths, a galley and toilet facility.
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 Avance 36 has been built with more than one type of 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 long keel.

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. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

Avance 36 can only enter major marinas as the draft is about 1.82 - 1.92 meter (5.97 - 6.27 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard Bukh DV20 diesel engine at 20.0 hp (14 kW), which gives a max speed about 5.2 knots.

The fuel tank which is made of steel has a capacity of 70 liters (18 US gallons, 15 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Avance 36 is 1.59, 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 Avance 36 is about 166 kg/cm, alternatively 931 lbs/inch.
Meaning: if you load 166 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 931 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Avance 36 is 28.2 - 31.0.

Comparing this ratio with similar sailboats show that it is more comfortable than 73% of all similar sailboat designs. This comfort value is just above average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Avance 36 is 3.91.

Compared with other similar sailboats it is slimmer than 98% 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 Avance 36 is 49%.

This ballast ratio shows a righting moment that is higher than 90% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

What is Displacement Length Ratio?

The DL-ratio for Avance 36 is 196 which categorizes this boat among 'light racers'.

76% 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 Avance 36 with ISO 8666 reference sail is 16.3, with a 135% genua the SA/D is 18.9.

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

The Avance 36 has more rig than 34% of all similar sailboats, which indicates that the boat is slightly underrigged.

What is Relative Speed Performance?

The Relative Speed Performance for Avance 36 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.
