Review of Maxi 77

Basic specs..

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 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 5 berths, a galley, 40.0 liter fresh water capacity and toilet facility.

The Maxi 77 is 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 Maxi 77 has been built with different keel alternatives.

Unknown keel type

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.

The boat can enter even shallow marinas as the draft is just about 1.15 - 1.25 meter (3.77 - 4.07 ft) dependent on the load. See immersion rate below.

One option is 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.

This keel is also made of iron.

Maxi 77 can enter even shallow marinas as the draft is just about 1.15 - 1.25 meter (3.77 - 4.07 ft) dependent on the load. See immersion rate below.

Another 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 full keel.

The boat can enter even shallow marinas as the draft is just about 1.37 - 1.47 meter (4.49 - 4.79 ft) dependent on the load. See immersion rate below.

The boat can enter even shallow marinas as the draft is just about 1.45 - 1.55 meter (4.76 - 5.06 ft) dependent on the load. See immersion rate below.

Maxi 77 may be equipped with an inboard Volvo Penta MD5A diesel engine at 7 hp (5 kW). Calculated max speed is about 4.4 knots

The transmission is a saildrive.

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 Maxi 77 is 2.00, indicating that this boat would not 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 6.3 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 Maxi 77 is about 113 kg/cm, alternatively 633 lbs/inch. Meaning: if you load 113 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 633 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 18m 2 (193 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.
