The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The Rival 34 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
The Rival 34 has been built with different keel alternatives.
Unknown keel type
The boat can enter even shallow marinas as the draft is just about 1.42 - 1.52 meter (4.66 - 4.96 ft) dependent on the load. See immersion rate below.
Fin keel
The Rival 34 is equipped with 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 1.78 - 1.88 meter (5.84 - 6.14 ft) dependent on the load. See immersion rate below.
Rival 34 may be equipped with an inboard Volvo Penta diesel engine at 25 hp (18 kW).
