Review of Amigo 33

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 many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 4-5 berths, a galley, 65.0 liter fresh water capacity 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 Amigo 33 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 Amigo 33 has been built with different keel alternatives.

Full keel

The Amigo 33 is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

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.

Amigo 33 can enter even shallow marinas as the draft is just about 1.40 - 1.50 meter (4.59 - 4.89 ft) dependent on the load. See immersion rate below.

Unknown keel type

The Amigo 33 has been equipped with different engine alternatives.

Alternative 1:

The boat may be equipped with an inboard Volvo Penta MD7 diesel engine

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

Alternative 2:

The boat may be equipped with an inboard Volvo Penta 2002 diesel engine at 21 hp (15 kW). The speed is 7.0 knots.

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

The fuel tank, which is made of stainless steel, has a capacity of 50.0 liters (13 US gallons, 10 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Amigo 33 is 1.81, 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 6.5 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 Amigo 33 is about 134 kg/cm, alternatively 751 lbs/inch.
Meaning: if you load 134 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 751 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Amigo 33 is 26.5.

What is L/B (Length Beam Ratio)?

The l/b ratio for Amigo 33 is 3.21.

What is a Ballast Ratio?

The ballast ratio for Amigo 33 is 45%.

What is Displacement Length Ratio?

The DL-ratio for Amigo 33 is 289 which categorizes this boat among 'medium weight cruisers'.

What is Relative Speed Performance?

The Relative Speed Performance for Amigo 33 is 15

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 23m² (247 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
