Review of Triss

Basic specs.

The Triss aka Triss Jollen is a small sailing dinghy designed by the Swedish maritime architect Per Brohäll in the late fifties. Several thousand boats have been produced. The Triss is built by the Swedish yard ABC Fabrikerna.

Here we would have liked to show you nice photos of the Triss.

Hull

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.

Rig

The Triss is equipped with a cat rig. A cat rig (also called an una rig) is simple to manage as there is no standing rigging, often referred to as “unstayed”. With only one sail it can be single-handed quite easily. The downside is its upwind performance.

Keel

CentreBoard

The Triss is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can sail close to the beach as the draft is just 0.15 - 0.25 meter (0.49 - 0.79 ft) dependent of the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Triss is about 43 kg/cm, alternatively 244 lbs/inch.
Meaning: if you load 43 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 244 lbs cargo on the boat it will sink 1 inch.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Triss is 2.71.

Compared with other similar dinghies it is slimmer than 62% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.
