Review of Sweden Yachts 370

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 interior is like many other boats made of mahogany.
The boat is equipped with 3 cabins, 4+2 berths, a galley, toilet facility and 80 liter waste water capacity.

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 Sweden Yachts 370 has been built with more than one type of keel.

One option is 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.But be aware that even though a Fin 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.

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 2.05 - 2.15 meter (6.73 - 7.03 ft) dependent on the load. See immersion rate below.

Sweden Yachts 370 is typically equipped with an inboard Volvo Penta MD2030 diesel engine at 29.0 hp (21 kW), which gives a max speed about 5.6 knots.

The fuel tank has a capacity of 150 liters (39 US gallons, 32 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sweden Yachts 370 is 1.94, 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 7.3 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 370 is about 221 kg/cm, alternatively 1242 lbs/inch.
Meaning: if you load 221 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1242 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Sweden Yachts 370 is 26.9.

Comparing this ratio with similar sailboats show that it is more comfortable than 46% of all similar sailboat designs. This comfort value is just below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Sweden Yachts 370 is 3.03.

Compared with other similar sailboats it is more spacy than 73% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Sweden Yachts 370 is 39%.

This ballast ratio shows a righting moment that is higher than 46% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.

What is Displacement Length Ratio?

The DL-ratio for Sweden Yachts 370 is 265 which categorizes this boat among 'light crusers & offshore racers'.

46% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.

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

The SA/D for Sweden Yachts 370 with ISO 8666 reference sail is 17.4, with a 135% genua the SA/D is 20.8.

The SA/D ratio indicates that it is faster than 58% of all similar sailboat designs in light wind.

The Sweden Yachts 370 has more rig than 50% of all similar sailboats, which indicates that this rig is spot on average!

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 39m² (419 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.
