Review of Finnsailer 34

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 boat is equipped with 3 cabins, 6 berths and 150.0 liter fresh water capacity.

The Finnsailer 34 is equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.

Fin keel

The Finnsailer 34 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 boat can enter most marinas as the draft is just about 1.58 - 1.68 meter (5.18 - 5.48 ft) dependent on the load. See immersion rate below.

Finnsailer 34 may be equipped with an inboard Perkins 4.108 M diesel engine at 37 hp (27 kW). Calculated max speed is about 6.7 knots

The fuel tank has a capacity of 200.0 liters (52 US gallons, 43 imperial gallons).

What is Capsize Screening Formula (CSF)?

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.0 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 Finnsailer 34 is about 196 kg/cm, alternatively 1097 lbs/inch.
Meaning: if you load 196 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1097 lbs cargo on the boat it will sink 1 inch.

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.
