Review of Aphrodite 101

The hull is made of hand laid 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 interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 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 Aphrodite 101 is equipped with 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.

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.

Aphrodite 101 can enter most marinas as the draft is just about 1.65 - 1.75 meter (5.41 - 5.71 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard Yanmar diesel engine at 9.0 hp (6 kW), which gives a max speed about 4.6 knots.

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 38.0 liters (10 US gallons, 8 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Aphrodite 101 is 1.73, 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 6.9 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 Aphrodite 101 is about 129 kg/cm, alternatively 726 lbs/inch.
Meaning: if you load 129 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 726 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Aphrodite 101 is 21.3.

Comparing this ratio with similar sailboats show that it is more comfortable than 31% of all similar sailboat designs. This comfort value is just below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Aphrodite 101 is 4.10.

Compared with other similar sailboats it is slimmer than 98% of all other designs. It seems that the designer has chosen a significantly more speedy hull design. This type of design is also referred to as 'needle'.

What is a Ballast Ratio?

The ballast ratio for Aphrodite 101 is 57%.

This ballast ratio shows a righting moment that is higher than 98% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

What is Displacement Length Ratio?

The DL-ratio for Aphrodite 101 is 152 which categorizes this boat among 'light racers'.

86% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Aphrodite 101 with ISO 8666 reference sail is 20.9, with a 135% genua the SA/D is 24.5.

The SA/D ratio indicates that it is faster than 95% of all similar sailboat designs in light wind.

The Aphrodite 101 has more rig than 73% of all similar sailboats, which indicates that the boat is slightly overrigged.

What is Relative Speed Performance?

The Relative Speed Performance for Aphrodite 101 is 85

The relative speed performance is 85 which means that a it is faster than 85% of all similar sailboat designs.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 24m² (258 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.
