Crazy Sister Marina is the busiest fishing operation on the Murrells Inlet Marshwalk, and it runs the widest menu of any boat in our Myrtle Beach field. From the marina’s New Inlet Princess head boat you can book a 4 hour sea bass trip, a shark trip, an 8 hour run to the Continental Shelf, an 11 hour Gulf Stream day, or a 24 hour overnight, all walk on and by the person, and the marina books three private six packs behind it for groups who want their own deck. The crew on the New Inlet Princess earns real praise for putting people on fish, which is what keeps Crazy Sister in the mix.
The verdict and where it ranks
At 6.7 Crazy Sister is a mixed pick and ranks third in Myrtle Beach, the top of the mixed band and just behind the head boat at Little River. Book it with caveats, and book it for the right trip. Its strengths are the trip menu and the crew: no other operator here offers as many ways onto the water, from a short family sea bass trip to a 24 hour overnight, and reviewers consistently single out the New Inlet Princess captain and mates. What holds it in the mixed band is the day to day experience on a busy walk on boat. The popular trips sail packed, a recurring complaint is a deck so full that lines spend much of the day tangled, and a visible minority of reviews describe a trip that went sideways. For a more consistent walk on day, Little River Fishing Fleet ranks higher, and for a private boat, The Reel leads the field. The full ranking is on the Myrtle Beach page.
The boats
The fishing headliner is the New Inlet Princess, a roughly 90 foot head boat that runs the bulk of the deep sea schedule, with the 110 foot Crazy Sister and the rest of the marina’s fleet handling cruises and overflow. Behind the head boat sit three private six packs: the 27 foot center console Reel Crazy, the 36 foot Yellowfin center console It’s a Write Off, and the 40 foot sportfisher Party Time, each booked for up to 6 anglers. That spread is the marina’s real edge, since it can match a boat to almost any group and trip. The honest problem is the head boat experience when the boat sails full. The deck gets crowded on the popular weekend trips, and the most repeated complaint in the reviews is tangled lines and not enough room, which is the trade a busy walk on boat always carries. The private boats avoid that, at a private boat price.
The fishing and what you target
Crazy Sister fishes the full Murrells Inlet range by trip length. The short trips work the nearshore for black sea bass and sharks, the kind of day that suits a family or a first timer. The 8 hour Continental Shelf trip reaches the mid range bottom for sea bass, vermilion snapper, triggerfish, and grouper, and the 11 hour Gulf Stream trip runs out to the deeper grounds for the bigger bottom fish and a shot at king mackerel and mahi mahi on the troll. The 24 hour overnight and the semi-private trips, capped at fewer anglers, are the way to reach the better water with more room. The bottom fishing carries the South Atlantic season rules: gag and the other shallow water grouper close January 1 to April 30, and red snapper has been closed since a federal court halted the 2026 state seasons in May, so the marina’s seasonal red snapper trips depend on the rule being reopened. Confirm the current limits with NOAA Fisheries and the South Carolina Department of Natural Resources before a season specific trip.
Trips and prices
The head boat pricing is clear and inclusive, and the menu is the broadest in the port. Adult fares run $49 for a 4 hour shark trip, $55 for a 4.5 hour sea bass trip, $109 for the 8 hour Continental Shelf trip, and $169 for the 11 hour Gulf Stream trip, with an 11 hour semi-private option at $199 that caps the boat at 45 anglers for more room. The rod, reel, bait, and license are covered. The 24 hour overnight is quoted separately, so call for that rate. The private boats are booked by the whole boat, from around $650 on the Reel Crazy up to roughly $1,350 to $1,500 on It’s a Write Off and Party Time, the option to choose if you want a private deck. The semi-private trip is worth flagging: paying a little more to cap the crowd directly answers the tangled deck complaint that runs through the reviews. Our cost guide and the party boat versus private charter guide compare the formats.
The crew
The New Inlet Princess crew is the best of the picture. Reviewers repeatedly name a captain, Robert among them, who finds the fish and works the day, and mates who know the job and stay on deck helping anglers rig, land, and clean their catch. On the trips that go well, the crew is the reason. The counterweight is consistency. Because the schedule is busy and the captains rotate, the experience varies with the boat, the crowd, and the day, and a minority of reviews describe a poorly handled trip, including a booking mix up that put anglers on the wrong boat. The marina’s overall review count runs into the thousands, but much of that volume is its cruises and tours rather than the fishing, so the fishing record is thinner than the headline number suggests. That spread, strong crew on a busy boat with real variability, is what the score reflects.
Booking and what to know
Book online or by phone, and choose the semi-private or a private boat if a crowded deck would spoil your day. The boats leave the marina on the Murrells Inlet Marshwalk, a walkable strip of docks and seafood restaurants south of Myrtle Beach proper, with parking at the marina. Arrive early to park, check in, and find your spot. Bring food and drinks for the longer trips, sunscreen, a hat, and a soft cooler with ice for your fillets, and motion sickness medication if you are unsure of your stomach on the 11 hour or overnight runs. Confirm the cancellation and weather policy when you book, since the long offshore trips are the first to move when the wind comes up.
How we scored it
Crazy Sister scores 6.7: the widest trip menu in the port, from a short sea bass trip to a 24 hour overnight, clear inclusive head boat prices, a private fleet for groups, and a New Inlet Princess crew reviewers rate highly, pulled into the mixed band by a crowded deck and tangled lines on the popular trips, a fishing record thinner than the marina’s headline review count, and a minority of poorly handled trips. Trips and access and value are its strongest factors.
