Maintenance Plans

Pick a cadence. Forget about it.

Recurring dives that keep your hull clean, your zincs fresh, and your boat ready to leave the slip whenever you are. Cancel anytime.

Active Boat
Out 4+ times a month? Clean every 2–3 weeks. Growth never gets a foothold, your fuel burn stays low, and your bottom paint lasts longer.
Idle Boat
Mostly at the slip? Clean every 4 weeks. San Diego water is warm enough that even unused boats grow growth fast — skipping months means scraping, not scrubbing.
Quarterly
Every 12 weeks
For boats that mostly stay clean and only need the occasional reset.

How It Works

Four steps. No surprises.

From first call to first dive, the process is built around your time, not ours.

01

You Send a Quote Request

Call, text, or fill the form. Tell me the boat, the marina, and what you need.

02

I Send a Real Quote

A real number — usually the same day — based on your boat, not a generic table.

03

I Dive Your Boat

Same-week scheduling. No need to be on-site. Hull, zincs, gear — handled in the water.

04

You Get the Video

Time-stamped underwater footage and a short written summary, sent to your phone.

Straight Pricing

From $2 per foot.

No mystery line items. The starting rate is $2/ft of waterline. The final number depends on what the boat needs — quoted before we touch the water.

$2/ foot · starting

Custom quotes after a quick look at your boat.

FACTOR 01

Bow Thruster

Side-mount propellers add complexity. We adjust for the time and care they need.

FACTOR 02

Oversized Metal

Larger rudders, struts, or trim plates take longer to scrub and inspect cleanly.

FACTOR 03

Paint Condition

Soft or worn antifouling needs a gentler hand. Hard paint takes more work.

Why CaliCoast

Built on the four things owners actually want.

Owner-Operated

Every dive on your boat is done by Gus. No rotating crew, no rushed subs, no "we'll send someone."

You See What We See

Underwater video, a written summary, zinc status, and photos of anything that needs attention — sent to your phone after every dive. Full transparency on hull, zincs, and gear.

Real Pricing

Starts at $2/ft, quoted to your specific boat before we touch the water. Never a surprise on the invoice.

We Show Up

Same-week scheduling. If something changes, you hear from us first — not after we missed the slot.

Service Area

All of San Diego Bay.

We're on the water every day and dive every major marina in San Diego County. If your slip's here, we can be there.

Slip in another marina? Ask anyway — we'll often add a stop if the route makes sense.

Gus Alves, founder of CaliCoast Marine Services
The Diver

Hi, I'm Gus.

I started CaliCoast Marine Services because boat owners deserve someone who actually shows up, on time, and treats the hull like it's their own.

Every dive on your boat is done by me — not subcontracted, not rushed. I check the zincs, scrub the hull, inspect the running gear, film the dive, and send you the video. If something looks off below the waterline, you'll be the first to know.

Same-week scheduling. Honest pricing. No surprises.

Common Questions

What boat owners ask us first.

How often should I clean my hull in San Diego?
In San Diego's water temperature, most owners book monthly cleanings (every 3–4 weeks) to stay ahead of growth. Boats that go out more often or live in warmer slips benefit from the monthly cadence. Quarterly is usually too long if you actually want speed and fuel efficiency.
How does your pricing actually work?
Rates per foot drop as cadence increases — that's how the math should work. Monthly is $2/ft because you book frequent visits and we keep your hull easy to clean. Bi-monthly is $2.75/ft, quarterly is $3.50/ft, single dives are $4/ft. Prepay a 4-pack to save another 8%, or a 12-pack annual to save 12% plus a free emergency dive. The final number adjusts for bow thruster, oversized metal, and paint condition — quoted before we touch the water, never on the invoice.
Do you clean the interior too?
Yes — interior detailing covers cabin, salon, galley, head, helm, and storage. Upholstery vacuumed, vinyl wiped, headliner refreshed, surfaces disinfected. $12/ft for a single visit, $10/ft on a monthly plan, or save 10% on both lines when you bundle interior with a hull cleaning on the same visit.
Do I need to be there when you dive?
No. We dive your boat at the slip with no need for you to be on-site. You get an underwater video and a short written summary after every visit so you see exactly what was done.
Are zincs included in the cleaning price?
Zinc inspection is free with every visit. If anodes need replacing, we use marine-grade zincs and charge cost-plus — you pay what I pay for the part plus my labor to install. No markup, no surprise fees. Note: zincs are a maintenance item, not a guaranteed-lifespan part. Some boats have electrical issues (stray current, bad shore-power grounds) that eat zincs faster than normal. If yours burns through unusually fast, I'll flag it so you can have an electrician check.
Can you help before a pre-purchase survey or haulout?
Yes — both. We dive boats for pre-purchase inspections (the underwater portion that informs the haulout decision) and we do pre-haulout cleaning so the yard sees the hull, not a year of growth. Either one saves you money downstream.
Do you have a referral program?
Yes. Refer a boat owner who books CaliCoast and completes 3 cleanings — your next cleaning is on the house. No referral codes, no app, no fine print. Just text Gus the friend's name and we'll track it on our end.
Do you handle emergencies — line in the prop, dropped item?
Yes. Line-in-prop, rope, kelp, lost keys, dropped phones, sunglasses — call or text and we'll get under the boat the same day whenever possible. Monthly maintenance customers get priority response.
Do you work with brokers, dealers, and charter fleets?
Yes — recurring fleet contracts, brokerage inventory service, and charter turnaround cleanings are all part of what we do. Volume pricing available. Just ask.
How do I cancel a maintenance plan?
There's no lock-in. You're billed per visit, not on a contract. If you want to pause for a haulout or cancel entirely, just text us.
