Review of Swede 38

The boat is equipped with 7 berths, a galley and toilet facility.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

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 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.

Swede 38 can only enter major marinas as the draft is about 1.90 - 2.00 meter (6.23 - 6.53 ft) dependent on the load. See immersion rate below.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Swede 38 is 1.54, 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 Swede 38 is about 170 kg/cm, alternatively 955 lbs/inch.
Meaning: if you load 170 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 955 lbs cargo on the boat it will sink 1 inch.

What is Displacement Length Ratio?

The DL-ratio for Swede 38 is 229 which categorizes this boat among 'light crusers & offshore racers'.

62% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

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

The SA/D for Swede 38 with ISO 8666 reference sail is 16.5, with a 135% genua the SA/D is 19.2.

The SA/D ratio indicates that it is faster than 42% of all similar sailboat designs in light wind.

The Swede 38 has more rig than 24% of all similar sailboats, which indicates that the boat is significantly underrigged.

What is Relative Speed Performance?

The Relative Speed Performance for Swede 38 is 62

The relative speed performance is 62 which means that a it is faster than 62% of all similar sailboat designs.

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.
