The third annual Stuart Sailfish Regatta kicked off Friday.
Saturday promises to be another day of excitement.
Spectators will see power boats, hydroplanes and other racing boats.
Some of the boats can get up to 170 mph.
The 1.1 mile race takes place north of the Stuart bridge, which is closed off so fans can enjoy the racing experience by seeing the boats from on top of the bridge.
More vendors have also been added to the event.
Spectators are allowed to bring umbrellas and folding chairs.
Race officials suggest people bring lots of sunscreen and several layers of clothing.
Activities start happening around 10 this morning.
Since the Stuart Bridge is closed, take the bridge in Jensen Beach to access A1A.
