Review of Sweden Yachts 70

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The hull is a sandwich construction 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 core material in the sandwich construction is balsa.

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 0 cabins, 8 berths, a galley, 1500.0 liter fresh water capacity, toilet facility and 240.0 liter waste water capacity.

The boat has more than one rig.

One option is 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.

Another option is 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 70 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.

Sweden Yachts 70 can only enter major marinas as the draft is about 2.60 - 2.70 meter (8.53 - 8.83 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.

The boat may be equipped with an inboard Volvo Penta TAMD 41D diesel engine at 170 hp (126 kW). Calculated max speed is about 8.5 knots

The fuel tank has a capacity of 1200.0 liters (317 US gallons, 263 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sweden Yachts 70 is 1.66, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Sweden Yachts 70 holds a CE certification:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 9.7 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 70 is about 555 kg/cm, alternatively 3109 lbs/inch.
Meaning: if you load 555 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 3109 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Sweden Yachts 70 is 4.10.

As balsa wood is used as sandwich core material special care must be taken in relation to work that require penetration of the sandwich construction in order to to prevent water to get in contact with the balsa wood. Otherwise the balsa wood will eventually rotten and be expensive/impossible to repair.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 93m² (1001 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.
