Ask about the launch fee and the parking. Ramp fees run free to ~$20; trailer parking fills before the ramp does on summer weekends. Some marinas open the ramp to the public but keep parking for slip holders.

Good to know

How much does it cost to launch a boat at a marina?

Public ramps at marinas typically charge $5-20 per launch or sell season passes; some waive the fee with fuel or slip rental. Municipal ramps are often free but offer no services — a marina ramp buys you fuel, a dock hand and a place to buy what you forgot.
