Crazy Sister Marina — Murrells Inlet Marina Guide
Crazy Sister Marina in Murrells Inlet, South Carolina: head boat and charter fishing, dolphin and sunset cruises, marsh eco tours, pontoon, skiff, kayak and jet ski rentals, dockage and boat services, and the MarshWalk next door.
By BeachLoco Editorial Team
Most marinas exist so that boats have somewhere to sit. Crazy Sister exists so that people without a boat can still get on the water. That is the essential difference between this place and almost every other marina on the Grand Strand, and it explains why a facility on a narrow tidal creek south of Myrtle Beach ends up on so many family itineraries.
Crazy Sister Marina sits on the Murrells Inlet waterfront on U.S. 17 Business, a few minutes from the MarshWalk. Dockage and boat services are part of the operation, but the front of the house is a booking counter: head boat fishing, private charters, dolphin cruises, sunset trips, eco tours, pirate adventures for kids, pontoon and skiff rentals, kayaks and jet skis. The marina has been operating here since 1985.
Why Crazy Sister Marina Matters
Murrells Inlet calls itself the seafood capital of South Carolina, and the description is earned by the working creek behind the restaurants rather than by the restaurants themselves. The inlet is a shallow, winding saltwater estuary that drains into the Atlantic through a single channel, and the boats that use it — shrimpers, headboats, center consoles, pontoons — all have to thread the same water.
Crazy Sister is the largest single point of public access to that system. If you are staying in Myrtle Beach or Surfside and want to go offshore, see dolphins, paddle the marsh or run a rented pontoon for an afternoon, this is the address most likely to have the right trip on the right day, because the range of what departs here is unusually wide.
That breadth is the point. A family with a nine-year-old, a serious angler wanting a Gulf Stream run and a couple who just want to be on the water at sunset can all book from the same dock, on the same weekend, without anyone compromising.
The Setting: Murrells Inlet and the Creek
The marina is centrally located in Murrells Inlet, just south of Myrtle Beach, with access to both the Intracoastal Waterway and the Atlantic. In practical terms, boats run out through the marsh channels and reach open ocean through Murrells Inlet itself.
What that means for a visitor is scenery on both ends of the trip. Even an offshore fishing day starts with twenty minutes of spartina grass, oyster banks, egrets and, frequently, dolphins working the tide line. The inlet is genuinely beautiful at the beginning and end of the day, which is why so many of the marina''s cruises are built around the marsh rather than the ocean.
It also means tides matter here more than at a deepwater harbor. Trip times are set around the water, not around convenience, and early departures are normal.
Head Boat Fishing: The Easiest Way Offshore
Head boat fishing — where you buy an individual ticket and share a large boat with other anglers — is the backbone of the operation, and it is the format most first-time saltwater anglers should start with. Rods, bait, tackle and crew help come with the ticket. You are not chartering a boat; you are buying a seat.
Crazy Sister runs a graduated ladder of these trips, and the differences are meaningful:
The 4.5-hour half-day "Sea Bass" trip is the entry point and the marina''s most popular option. Nearshore bottom fishing, moderate run time, plenty of action for people who mostly want to catch something.
The 4-hour "Shark" trip is a family-oriented alternative aimed at the thrill rather than the cooler — a good pick for kids old enough to want a story out of the day.
The 4.5-hour "Take a Kid Fishing" trip is exactly what the name says and is structured for all ages.
The 8-hour "Continental Shelf" trip is the first real offshore day: longer run, deeper bottom, larger fish, and a genuine commitment of the whole day.
The 11-hour "Gulf Stream" deep sea trip and its semi-private version go far enough out to change the species list entirely.
Specialty long trips — a 12-hour semi-private Gulf Stream jigging trip and a 24-hour overnight — exist for experienced anglers who want the serious version.
If you have never fished offshore, be honest about seasickness and about what a full day at sea feels like before booking eight or eleven hours. The 4.5-hour trips exist for a reason and nobody regrets starting there.
Charter Fishing and Semi-Private Trips
Private charter fishing is the other half of the fishing program, and the fleet is built around three boat types: a 27-foot Gamefish center console, a 36-foot Yellowfin center console and a 40-foot Sportfish. Independent charter operators also run from the marina.
A private charter means the boat and crew are yours: you choose the trip, you are not sharing rail space, and the captain can adjust based on how the day is going. It costs more, and for a group of four to six it is often the better value once you divide it.
The marina also runs "super semi-private" trips on the 40-foot Sportfish with capped angler counts — a 10-hour bottom fishing charter limited to ten anglers, and a red snapper version capped at twelve. This is the useful middle ground: a large comfortable boat and a real offshore day, with a fraction of the crowd of a full head boat, at a per-person ticket rather than a whole-boat price. Red snapper trips run only in the short federal season, so check timing before you plan around one.

Cruises: Dolphins, Sunsets and the Marsh
The cruise program is the reason a lot of people come here who would never book a fishing trip. It is organized into recognizable families:
Dolphin tours. Several formats run, including a Dolphin & Sealife Cruise, an Ocean Sunset Dolphin & Sealife Cruise, a Lighthouse Dolphin Cruise and dolphin watch tours operated with Blue Wave Adventures. Bottlenose dolphins are resident in these waters year-round, and the inlet''s tidal creeks are working territory for them.
Sunset cruises. An Inlet Sunset Cruise stays inside the marsh; the ocean sunset trip runs out through the inlet. There is also a private 20-passenger sunset option for groups.
Eco and nature tours. A Saltwater Marsh Eco Tour and an Inlet Bird Watching Tour take the estuary seriously rather than treating it as scenery, which makes them the most rewarding trips on the list for anyone interested in what the marsh actually is.
Narrated and history cruises. A 75-minute Murrells Inlet History Cruise covers coastal history, pirate legend and Civil War stories along the waterfront.
Kids'' pirate adventures. The Children''s Pirate Adventure and its sunset version are costumed, participatory trips built entirely for young children, and they are among the marina''s signature offerings.
Specialty cruises. Ghost story cruises, full moon trips, a wine sampling sail, a stretch-and-sip cruise, a murder mystery dessert cruise and seasonal fireworks cruises rotate through the calendar.
The schedule changes by season and by holiday, so treat the list as a menu of what the marina does rather than what is running on a given Tuesday.
Rentals: Pontoons, Skiffs, Kayaks and Jet Skis
If you would rather drive yourself, the rental fleet covers most of the ways to do it.
Pontoon rentals are the family default — stable, slow, shaded and forgiving, and well matched to the inlet''s protected water. Renters must be 21 or older.
17-foot Carolina Skiff rentals suit small groups who want to fish the creeks under their own power. Also 21 and up.
Kayak rentals — single and tandem — are the best way to see the marsh channels at close range, and there is a two-hour guided kayak tour for people who would rather not navigate on their own. The kayak minimum age is three.
Jet ski rentals run in 60-minute blocks for ages 18 and up, and there is a jet ski dolphin tour as well as a Seakart adventure for something faster.
Two things worth knowing before you book a self-drive rental in Murrells Inlet: the inlet is shallow and shoals move, and the creek is busy on summer weekends. Take the briefing seriously and keep an eye on the tide.
Dockage and Boat Services
The marina side of the business is smaller in visitor terms but real. Crazy Sister offers both annual dockage for local owners, frequent anglers and seasonal residents, and transient dockage for privately owned boats, crew and support vessels, salvage boats, dive boats and travelling boaters — for a night, a few days or several weeks.
The marina''s own positioning is that its location makes docking, fueling and resupplying simple for boats running the South Carolina coast or heading offshore. Current dockage rates are quoted on the marina''s booking page rather than published here.
On-site boat services include oil changes, bottom paint, bottom cleaning, detailing, water pump service, spark plug replacement and marine electronics installation and diagnostics. There is also a Crazy Sister Boat Club with skiff and fleet memberships for people who want regular water time without owning a boat.
What Departing from Crazy Sister Is Actually Like
Arrive early. The parking lot fills, the check-in counter has a line in summer, and boats leave on time because they are working around tide and daylight rather than around stragglers.
The dock itself is busy in a good way — headboats loading, charter captains rigging, kayaks going out, a pontoon backing off the end of the pier. It is not a quiet, manicured resort marina, and that is a large part of its appeal.
Bring sun protection, water and a jacket even in shoulder season; the temperature on the ocean bears little relationship to the temperature in the parking lot. For any trip over four hours, food matters more than people expect. And if you are prone to motion sickness, take something the night before, not at the dock.
The MarshWalk and the Waterfront Next Door
The single biggest advantage of a Crazy Sister trip is what is waiting when you come back in. The Murrells Inlet MarshWalk — a half-mile boardwalk along the creek lined with waterfront seafood restaurants and live music decks — is minutes from the marina, and an afternoon cruise followed by dinner on the water is the classic Murrells Inlet evening.
This is the best-known seafood stretch on the Grand Strand, and it is a genuinely different experience from oceanfront dining in Myrtle Beach: you are looking at a working marsh rather than at surf. If you would rather have the ocean view, Sea Captain''s House up in Myrtle Beach is the long-running counterpoint.
Brookgreen Gardens and Huntington Beach State Park are both a short drive south, which makes a morning cruise and an afternoon inland a very easy day to build.

Who Crazy Sister Marina Is Best For
Families with young children. The pirate adventures, the kid fishing trip and the short dolphin cruises are built for this audience, and few marinas anywhere do it as thoroughly.
First-time saltwater anglers. Head boat tickets remove every barrier — no gear, no boat, no planning — and the 4.5-hour trips are a sensible first step.
Serious offshore anglers. The Gulf Stream trips, jigging specialty runs, the 24-hour overnight and the capped semi-private charters cover the deep end properly.
Non-fishing travelers who want water time. Sunset cruises, eco tours, kayaks and pontoons make this a legitimate stop for people with no interest in fishing at all.
Boat owners in the Murrells Inlet area. Annual dockage, maintenance and the boat club are the local-resident side of the operation.
Less suited to: cruisers looking for a large resort-style marina with a pool and hotel-grade amenities. For that on the Grand Strand, Barefoot Marina and Grande Dunes Marina are the relevant facilities.
Practical Tips
Book ahead in summer. The popular half-day trips and the pirate adventures fill, particularly on weekends and around holidays.
Match the trip length to the passengers, not the ambition. An eleven-hour offshore day is a long time for anyone who has not done it before.
Check the tide chart. The marina publishes one, and it explains why departure times move around.
Plan dinner on the MarshWalk around your return time, not the other way round — boats come back when they come back.
Confirm age minimums before booking rentals. Pontoons and skiffs require a renter aged 21 or older; jet skis are 18 and up.
Ask about red snapper timing. Those trips depend on a short federal season and cannot be planned around casually.

Yes. The Children''s Pirate Adventure and its sunset version are designed for young kids, the "Take a Kid Fishing" trip is all ages, and the shorter dolphin cruises suit families well.
Can I see dolphins?
Dolphin cruises are a core part of the schedule and bottlenose dolphins are resident year-round in these waters, though as with any wildlife trip sightings are not guaranteed.
Can I rent a boat without a captain?
Yes — pontoons, 17-foot Carolina Skiffs, kayaks and jet skis are all available as rentals. Pontoon and skiff renters must be at least 21; jet ski renters at least 18.
Can I dock my own boat at Crazy Sister?
Yes. Annual dockage and transient dockage are both offered, with rates quoted through the marina.
Is the marina near the Murrells Inlet MarshWalk?
Yes — the MarshWalk and its waterfront restaurants are minutes away, which is why cruise-then-dinner is such a common plan here.
What are the marina''s hours?
The marina publishes hours of 6:00 a.m. to 8:30 p.m., seven days a week. Individual trips depart on their own schedules.
Planning the Rest of Your Trip
Murrells Inlet works best as part of a wider Grand Strand trip. Start with the Myrtle Beach destination guide, then things to do in Myrtle Beach for the land side and the best beaches along the Grand Strand for the sand.
Anglers should read the Myrtle Beach fishing charters guide alongside this one, and boaters can compare the two northern marinas — Grande Dunes Marina on the waterway in Myrtle Beach and Barefoot Marina at mile marker 354.
For the rest of the planning, resort options, snorkeling near Myrtle Beach and the Ocean Drive shag clubs cover where to stay, what else to do on the water and the most distinctly local night out on this coast. If you are timing a visit, Myrtle Beach Bike Week and the Myrtle Beach Jeep Jam both fill the area while they run — check the events calendar before booking.
