Review of Finngulf 28 e

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

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 boat is typically equipped with an inboard Volvo Penta MD2020 diesel engine at 18.0 hp (13 kW), which gives a max speed about 6.0 knots.

The transmission is a saildrive.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Finngulf 28 e is 2.00, 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 6.7 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 Finngulf 28 e is about 149 kg/cm, alternatively 837 lbs/inch.
Meaning: if you load 149 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 837 lbs cargo on the boat it will sink 1 inch.
