Review of Sweden Yachts 340

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.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The deck is a double deck which improves the indoor climate.

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 3 cabins, 6 berths, a galley, 180.0 liter fresh water capacity, toilet facility and 80.0 liter waste water capacity.

The Sweden Yachts 340 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 Sweden Yachts 340 has been built with different keel alternatives.

Fin keel

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.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can only enter major marinas as the draft is about 1.95 - 2.05 meter (6.40 - 6.70 ft) dependent on the load. See immersion rate below.

Wing keel

But be aware that even though a Wing Keel keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

Sweden Yachts 340 can enter most marinas as the draft is just about 1.55 - 1.65 meter (5.09 - 5.39 ft) dependent on the load. See immersion rate below.

Fin keel

Another 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.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can only enter major marinas as the draft is about 2.02 - 2.12 meter (6.63 - 6.93 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta MD2030 diesel engine at 29 hp (21 kW). The speed is 7.0 knots.

The transmission is a saildrive.

The fuel tank, which is made of stainless steel, has a capacity of 150.0 liters (39 US gallons, 32 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sweden Yachts 340 is 1.98, 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 7.1 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 Sweden Yachts 340 is about 199 kg/cm, alternatively 1116 lbs/inch.
Meaning: if you load 199 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1116 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Sweden Yachts 340 is 25.1.

What is L/B (Length Beam Ratio)?

The l/b ratio for Sweden Yachts 340 is 2.97.

What is a Ballast Ratio?

The ballast ratio for Sweden Yachts 340 is 41%.

What is Displacement Length Ratio?

The DL-ratio for Sweden Yachts 340 is 258 which categorizes this boat among 'light crusers & offshore racers'.

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

The SA/D for Sweden Yachts 340 with ISO 8666 reference sail is 17.5, with a 135% genua the SA/D is 20.9.

What is Relative Speed Performance?

The Relative Speed Performance for Sweden Yachts 340 is 76

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 35m² (376 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.
