Review of First 300 Spirit

The hull 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 few other boats made in cherry.
The boat is equipped with 3 cabins, 5 berths, a galley, 90.0 liter fresh water capacity and toilet facility.

The First 300 Spirit is 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 gennaker or a spinnaker for optimal speed.

Fin keel

The First 300 Spirit 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 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 only enter major marinas as the draft is about 1.82 - 1.92 meter (5.97 - 6.27 ft) dependent on the load. See immersion rate below.

First 300 Spirit may be equipped with an inboard Yanmar diesel engine at 9 hp (6 kW). Calculated max speed is about 4.6 knots

The fuel tank has a capacity of 30.0 liters (7 US gallons, 6 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for First 300 Spirit is 2.06, 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 7.2 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 First 300 Spirit is about 175 kg/cm, alternatively 983 lbs/inch.
Meaning: if you load 175 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 983 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for First 300 Spirit is 17.1.

What is L/B (Length Beam Ratio)?

The l/b ratio for First 300 Spirit is 3.03.

What is a Ballast Ratio?

The ballast ratio for First 300 Spirit is 33%.

What is Displacement Length Ratio?

The DL-ratio for First 300 Spirit is 122 which categorizes this boat among 'ultra light racers'.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 32m² (344 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.
