Review of Sunwind 26

The boat is equipped with 5 berths, a galley, 60.0 liter fresh water capacity and toilet facility.

The Sunwind 26 is 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 gennaker or a spinnaker for optimal speed.

Fin keel

The Sunwind 26 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

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. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.

Sunwind 26 may be equipped with an inboard Volvo Penta MD5A diesel engine at 7 hp (5 kW). Calculated max speed is about 3.8 knots

The transmission is a saildrive.

The fuel tank has a capacity of 25.0 liters (6 US gallons, 5 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 6.1 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 Sunwind 26 is about 111 kg/cm, alternatively 626 lbs/inch.
Meaning: if you load 111 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 626 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 20m² (215 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.
