Review of Hanse 415

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The boat is equipped with a galley, toilet facility and 35.0 liter waste water capacity.

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 Hanse 415 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.But be aware that even though a T keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

Another option is a L keel. The keel is an L-shape and therefore less exposed to seaweed, fishing nets and lines.

The boat can only enter major marinas as the draft is about 2.10 - 2.20 meter (6.89 - 7.19 ft) dependent on the load. See immersion rate below.

Hanse 415 is typically equipped with an inboard Volvo Penta D2-40 diesel engine at 38.0 hp (28 kW).

The transmission is a saildrive.

The fuel tank has a capacity of 160.0 liters (42 US gallons, 35 imperial gallons).

Hanse 415 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 8.2 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 Hanse 415 is about 318 kg/cm, alternatively 1783 lbs/inch.
Meaning: if you load 318 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1783 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Hanse 415 is 2.88.

Compared with other similar sailboats it is more spacy than 86% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

The Hanse 415 has more rig than 92% 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 54m² (581 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.
