The Short Answer: What a Slip Costs in San Diego
For a typical 30-foot slip in San Diego, expect to pay roughly $700–$1,500 a month — $8,400 to $18,000 a year — depending on the marina, the location on the bay, and what’s included. Around Point Loma and Shelter Island, where most of the boating action is, a 30-footer typically runs $1,100–$1,500+ a month.
That range surprises people in both directions. Compared to other West Coast cities, San Diego is actually reasonable. Compared to what most first-time buyers budget, it’s a wake-up call — because the slip is just the cover charge. More on that below.
Marina-by-Marina Rates (2026)
Rates below are approximate monthly ranges for a 30-foot slip, based on 2026 published rates and market reports. Marinas adjust seasonally, and exact pricing depends on slip location within the marina, beam width, and liveaboard status.
| Marina | Area | ~Monthly for 30′ | Notes |
|---|---|---|---|
| Point Loma Marina | Point Loma | $1,100 – $1,400 | Full-service, fuel dock, close to the bay entrance |
| Shelter Island Marina | Shelter Island | $1,000 – $1,350 | Competitive rates, active boating community |
| Marina Village / Harbor Island | Harbor Island | $900 – $1,200 | Central bay location, amenities |
| Sunroad Resort Marina | Harbor Island | $1,100 – $1,500 | Resort-style, premium pricing |
| Cabrillo Isle Marina | Harbor Island | $950 – $1,300 | Well-maintained, good location |
| Driscoll’s Wharf / Commercial Basin | Point Loma | $800 – $1,100 | More working-marina feel, better value |
| Chula Vista Marina | South Bay | $700 – $950 | Best value on the bay, longer run to open water |
| Pier 32 Marina | South Bay | $700 – $1,000 | National City area, budget-friendly |
Two things to notice: first, the spread between the cheapest and priciest 30-foot slip on the same bay is roughly 2x — location matters enormously. Second, none of these numbers include electricity, insurance requirements, or maintenance — they’re just the parking spot.
The Waitlist Reality
Here’s what the rate tables don’t tell you: getting a slip in San Diego can take months or years. The desirable marinas — Point Loma, Shelter Island, Harbor Island — run waitlists, especially for 30+ foot slips and end ties. Some boaters buy the boat first and discover they have nowhere to put it, ending up on a waitlist while paying for dry storage or a temporary sublease at premium rates.
Call the marina before you buy the boat. Ask about current availability for your length, the waitlist depth, and what subleases actually cost. This single phone call saves more deals than any sea trial.
What Your Slip Really Costs Per Year
The monthly rate is the beginning, not the end. The true annual cost of keeping a boat in a slip:
- Slip rent: $8,400–$18,000/year (the table above)
- Electricity: $50–$150/month for metered slips — $600–$1,800/year
- Insurance: most marinas require liability coverage, typically $300–$600/year for a mid-size boat
- Bottom cleaning: monthly hull cleaning runs $100–$200/visit in San Diego — $1,200–$2,400/year
- Bottom paint: every 2–3 years, $3,000–$6,000 — amortize ~$1,500–$2,500/year
All in, a “$1,200/month slip” is really a $18,000–$25,000/year commitment before you’ve bought a gallon of fuel or fixed a single thing on the boat. And that’s before depreciation, financing, and the maintenance budget (figure ~10% of the boat’s value per year).
The Honest Comparison: Slip vs. Boat Club
Let’s be blunt: a bare slip rental is cheaper than boat club dues. If you already own a boat, maintain it yourself, and just need a parking spot, no club membership competes with $1,200 a month.
But that’s the wrong comparison for most people reading this. The right comparison is the slip plus everything else:
- Slip: $13,200–$18,000/year
- Insurance, maintenance, repairs: $15,000–$25,000/year
- Depreciation and financing: $20,000–$35,000/year
- Your time managing all of it: significant
Against that $50,000+/year total, club dues of roughly $9,000–$18,000 a year — initiation plus one monthly number, everything handled — start to look very different. The slip was never the expensive part of owning a boat. Everything around the slip is.
Frequently Asked Questions
How much is a boat slip in San Diego per month?
For a 30-foot slip, roughly $700–$1,500/month depending on the marina. Point Loma and Shelter Island run $1,000–$1,500+; South Bay marinas run $700–$1,000.
Are there waitlists for slips in San Diego?
Yes — the popular marinas (Point Loma, Shelter Island, Harbor Island) commonly have waitlists for 30+ foot slips. Always call about availability before buying a boat.
What size slip do I need for a 28-foot boat?
A 30-foot slip is the standard fit for a 28-foot boat — marinas charge by slip length, and you want buffer for fenders, swim platforms, and outboards.
Does slip rent include electricity and water?
Water is usually included; electricity is often metered separately ($50–$150/month). Insurance, bottom cleaning, and maintenance are always extra.
Is it cheaper to keep a boat in dry storage?
Dry storage runs cheaper monthly but adds launch fees, scheduling friction, and trailer maintenance — and most 28+ foot boats aren’t trailerable anyway.
Can I live aboard in a San Diego marina?
Some marinas allow a limited number of liveaboards with additional fees and stricter requirements; most have waitlists specifically for liveaboard slips. Check with the individual marina.
The Bottom Line
A boat slip in San Diego costs roughly $700–$1,500 a month for a 30-footer — but the slip is the smallest line item in boat ownership. Before you buy, price the whole picture: slip, insurance, maintenance, depreciation, and your time.
