The hull is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The Asso 99 is built with a fractional rig. The sail area for the mailsail + jib is 41.7 m2 (449.0 ft2). 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 with bulb
The Asso 99 is built 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 advantage of the bulb is that it lowers the center of gravity which increases the righting moment and reduces the draft.
The boat can enter most marinas as the draft is just about 1.71 - 1.81 meter (5.61 - 5.91 ft) dependent on the load.
