Review of Forgus 37

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

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, 300.0 liter fresh water capacity, toilet facility and 100.0 liter waste water capacity.

The Forgus 37 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 boat can enter most marinas as the draft is just about 1.58 - 1.68 meter (5.18 - 5.48 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.

Fin keel

Another 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 full keel.

Forgus 37 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.

The boat may be equipped with an inboard Volvo Penta MD22L diesel engine at 48 hp (35 kW). Calculated max speed is about 7.1 knots

The fuel tank has a capacity of 210.0 liters (55 US gallons, 46 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 7.5 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 Forgus 37 is about 223 kg/cm, alternatively 1253 lbs/inch.
Meaning: if you load 223 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1253 lbs cargo on the boat it will sink 1 inch.

What is Relative Speed Performance?

The Relative Speed Performance for Forgus 37 is 38

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 36m² (387 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.
