90 Days
Sojourners ( Dual Registration) A non-resident boater with a valid out-of-state registration certificate may use his/her vessel in Florida waters for 90 days without applying for a Florida registration. This applies to pleasure boats only. If the nonresident intends to use the craft in Florida longer than 90 days, the boat must be registered with the Department of Environmental Protection which is processed at the Tax Collector's Office. http://www.okaloosatax.com/vessel.html
