Review of Naver 27

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 deck is a double deck which improves the indoor climate.

The interior is like many other boats made of mahogany.
The boat is equipped with 5 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 Naver 27 is equipped with 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 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.

Naver 27 can enter even shallow marinas as the draft is just about 1.42 - 1.52 meter (4.66 - 4.96 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard Bukh DV8 diesel engine at 8.0 hp (5 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of stainless steel has a capacity of 40.0 liters (10 US gallons, 8 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Naver 27 is 2.01, indicating that this boat would not be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Naver 27 is about 152 kg/cm, alternatively 851 lbs/inch.
Meaning: if you load 152 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 851 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Naver 27 is 3.02.

Compared with other similar sailboats it is more spacy than 54% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Naver 27 is 51%.

This ballast ratio shows a righting moment that is higher than 92% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

What is Relative Speed Performance?

The Relative Speed Performance for Naver 27 is 27

The relative speed performance is 27 which means that a it is faster than 27% of all similar sailboat designs.
