Review of Bumerang 32

Basic specs..

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid 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. Unfortunately, the hull is not a double hull which affects the indoor climate. Especially if the water is considerable colder than the cabin, then one might expect condense water in the cabin. The deck is a double deck which improves the indoor climate.

The boat is equipped with 5 berths and 65.0 liter fresh water capacity. 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 Bumerang 32 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 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.

Bumerang 32 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 is typically equipped with an inboard Yanmar 1GM diesel engine at 7.0 hp (5 kW), which gives a max speed about 3.7 knots.

The fuel tank has a capacity of 22.0 liters (5 US gallons, 4 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Bumerang 32 is 1.68, 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 7.1 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 Bumerang 32 is about 145 kg/cm, alternatively 813 lbs/inch. Meaning: if you load 145 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 813 lbs cargo on the boat it will sink 1 inch.

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 27m 2 (290 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.
