Documentation Renewal is Easy
For the Federal Documentation (administered by the USCG) the renewal is semi-automatic and free. The Documentation period is 12 months, and prior to expiration the USCG automatically sends you a short renewal form to sign & return (OK, it does cost the price of a postage stamp!). The form allows you to certify that everything is still as stated, or to make any corrections/changes (which can incur a fee, depending upon what changes).You are, of course, still liable to your State of primary usage for any taxes & fees. Federal documentation does NOT include your tender/dinghy; it must be State registered and numbered.--RonD
