Finding a marina for an extended stay — a season, a year, or longer — is a fundamentally different process than booking a transient slip. One-night guests experience the parking lot, the fuel dock, and the bathhouse on a Thursday evening. Liveaboards experience the 6 a.m. generator that wakes them when the boat next door charges batteries, the surge that makes the dock creak every 90 seconds from a westerly swell, the bathhouse on a Saturday morning when sixteen boats share three showers, and the dock master who either has a reasonable attitude toward people who actually live aboard or doesn't. The marketing materials don't cover any of this. The 12 criteria below are what experienced liveaboards check before they sign anything.
1. Whether Liveaboards Are Actually Allowed
The majority of marinas in the United States do not permit liveaboards. Not just reluctantly — they actively prohibit it, either because of zoning requirements, their insurance policy, or a management decision that liveaboards complicate operations. Before you evaluate anything else about a marina, confirm that liveaboard status is permitted for the type of slip you're considering.
Many marinas that technically allow liveaboards cap the percentage of slips that can have full-time residents — commonly 10–20% of total slips. If they're at that cap, you may be on a waiting list regardless of slip availability. Ask specifically: "Do you have liveaboard slips available, and if so, how many?"
2. The Liveaboard Surcharge
Facilities that permit liveaboards typically charge a monthly surcharge on top of the base slip rate — anywhere from $100 to $300/month depending on the marina. This fee nominally covers increased use of amenities (showers, laundry, common areas) and the administrative overhead of treating the slip as a residence. It's a real number and not usually negotiable. Work it into your comparison cost before you decide between facilities.
3. Electricity Billing: Metered vs. Flat Rate vs. Included
This is the variable most likely to produce monthly budget surprises. Electricity billing at marinas falls into three models: metered at the pedestal (you pay what you use at per-kilowatt-hour rates), a flat monthly addition to the slip fee, or included in the base rate. The difference matters enormously for liveaboards who run air conditioning in summer or any kind of heating in winter.
A boat on 50-amp service running one air conditioner in a Florida summer can draw 20–30 kilowatt-hours per day. At metered rates of $0.15–$0.25/kWh, that's $90–$225 per month in electricity alone. A flat rate of $100/month would be a bargain in that scenario; included electricity is even better. Get the specific billing structure in writing before you sign — "electricity available" tells you nothing useful.
4. Shore Power Quality and Pedestal Reliability
Older marinas built in the 1970s and 1980s were wired with 30-amp infrastructure. Many have added 50-amp pedestals without upgrading the underlying distribution system, resulting in nominally 50-amp service that can't sustain full load on hot summer days. Ask how old the electrical system is and when it was last inspected or upgraded. A marina that can't answer this question with specifics is a marina whose shore power should be verified with your own meter before you commit.
Shared pedestals — where two slips split a single 50-amp connection — are common in older facilities and a meaningful problem for liveaboards with high electrical loads. Ask whether each slip has a dedicated pedestal. If the answer is that it depends on the slip, ask specifically about yours.
5. The Bathhouse: Actual Condition and Capacity
A marina's bathhouse on a weekday morning in September tells you very little about the bathhouse on a Saturday morning in July when the marina is full of weekend boats. Before you sign an annual contract, visit on a busy weekend morning. Count the showers. Look at the tile, the drains, the hot water situation. Ask liveaboards already at the marina whether there are enough showers for the full-season population — not the off-season population that exists when the sales office gives you a tour.
Facilities that have invested seriously in their bathhouse — individual lockable shower rooms, consistent hot water from tankless or large-capacity systems, regular cleaning staff — are a meaningful quality of life indicator. Liveaboards who spend months at a facility use the bathhouse 300 or 400 times. The quality of that infrastructure matters.
6. Laundry: Availability and Machine Condition
Marina laundry facilities range from two coin-operated machines in a shed to a proper laundry room with adequate capacity for the full marina population. Find out how many machines serve how many slips. An eight-machine laundry room for 40 slips is adequate; two machines for 120 slips produces the kind of scheduling friction that becomes a regular frustration after six months.
7. Pump-Out Access and Frequency
In most US coastal states, discharging untreated sewage overboard is prohibited. Liveaboards fill their holding tanks faster than weekend boaters. The pump-out situation at a marina — whether it's on-site or requires a trip to another facility, whether it's self-serve or needs an attendant, whether it's free or charged per use — directly affects routine operations.
A marina that requires you to go to an off-site pump-out facility is a meaningful inconvenience when you're anchored in a slip and your holding tank needs servicing every one to two weeks. Ask not just whether pump-out exists but what the typical wait time is during busy periods and what happens if the station is out of service.
8. Parking: Number of Spots and Walk Distance
Urban marinas frequently offer one parking spot per slip, with overflow on a first-come basis or separate monthly fee. If you have a car — or two — and the marina's lot is undersized for its full-season population, finding parking after 5 p.m. becomes a recurring problem. Ask how many parking spaces are allocated to your slip and what the overflow policy is. Visit in the evening when the lot is actually full to see what the real situation looks like.
9. Security: Actual Access Control, Not Just a Sign
Marina security ranges from a locked gate with access codes to nothing. For liveaboards, security affects not just boat safety but personal safety walking the docks at midnight. Look at the gate mechanism: is it actually locked, or is it propped open? Is there a camera? Is there a night attendant, or is security entirely based on gate codes that are commonly shared? Talking to existing liveaboards about any security incidents in the past year is more useful than anything the marina staff will tell you.
10. Wi-Fi Quality — and the Realistic Alternative
Marina Wi-Fi is almost universally inadequate for anyone who works remotely or streams video regularly. The shared bandwidth across a full marina, combined with the RF-hostile environment of aluminum masts and stainless rigging, makes marina Wi-Fi a supplemental convenience at best. Before you choose a marina as a remote-work base, check cellular coverage from a boat in the slip — not from the marina office — with the carriers that cover the area. A 5G signal on the dock is worth far more than fast marina Wi-Fi on shore that doesn't reach your boat.
Starlink's marina-targeted flat-rate plan at approximately $135–$165/month has changed this equation for liveaboards who need reliable connectivity. It's a meaningful monthly cost but one that removes the marina's internet infrastructure from the equation entirely.
11. Noise: The 24-Hour Profile, Not Just the Afternoon
A marina that feels quiet on a Tuesday afternoon may have a charter fleet that idles out at 6 a.m. on Saturdays, a fuel dock that runs generators from 7 a.m., or a bar on the premises that goes until midnight on summer weekends. Ask specifically about the noise profile at different times of day and days of the week. Existing liveaboards will tell you the truth; the marina's marketing materials will not.
12. The Management's Actual Attitude Toward Liveaboards
This is the hardest to quantify and the most important. Some marinas welcome liveaboards as stable, engaged tenants who take care of their boats and contribute to the community. Others tolerate liveaboards as a necessary revenue source while making the arrangement as inconvenient as possible — strict guest policies, no working on the boat in the slip, limited common-area access. The management's attitude shapes daily life in ways that no amenity list captures.
Talk to existing liveaboards — not the ones the marina refers you to, but the ones you find on your own by walking the docks and introducing yourself. Ask what management is actually like, how billing disputes get handled, and whether the rules as written match the rules as enforced. The answers to those questions tell you more than a tour of the facilities ever will.
