"Best boat ride ever!!!!!"
June 2019
The captain and Mate were amazing. I observed his knowledge of the water and courtesy for other boaters. We were able to see numerous dolpins and a possible hammerhead shark. Overall this was an amazing experience and highly recommend.. even though someone hit our truck in the parking lot.

"Great customer service"
August 2018
My family and I went on the Sea Thunder at the end of July. Since the weather that week had not been great the captain wasn't able to find any dolphins after many attempts. We were disappointed but they gave every group on the boat a card and a text with a coupon code that will allow us to make a reservation for free for the same number of people. We can go back for free as many times as necessary until we see dolphins. I think this is great. Other than no dolphins the boat ride was fun and you get soaked.

"Sea Thunder not so much"
June 2018
While I planned to get to the location an hour ahead of time, plans change with 3 small kids, plus the rotating bridge delayed us getting across on time. So, we were there 30 minutes ahead of time; that meant that we were placed in the last group and we had to sit in the back where the seating is cramped and you cannot see ahead. We were booked for the Sea Thunder but they apparently had a mechanical or other issue and we had to ride on the Sea Screamer, neither of which ever really went very fast. My nephews were pretty bored with the whole thing (ages 6, 7 and 11). It was a pleasant enough ride out to the ocean but I would probably not do it again. The captain tried to find some dolphins for us but we only saw them above the water very briefly a few times. I was disappointed that the kids did not get a seat by the side of the boat or in front. We would have a much, much better time on my boat at the lake. Also, I dislike being asked for tips when I'm already spending a small fortune on my family vacation.

Tip: You should probably be there at least an hour and a half ahead of time, so you can maybe sit in front, or at least on the side nearest the water. It's a pretty slow ride so, if you are looking for something fast, this is not it. It's hard to get good photos with all of the people packed into the boat (around 150). They will ask for a tip at the end and tell you the mate only works for tips. Nice guys but I find that offensive.

We went with family on this cruise excursion and it was a great experience! We got to see many dolphins and the boat ride out was a blast! Prepare to get wet but it's a lot of fun. The staff was great too. Highly recommend going on this excursion.

Wonderful experience. The Captain and crew were great. We had plenty of space and sat in the shade with a whole row to ourselves. Arrive and check-in early if you want to have a chance at sitting under the canopy. I thought we might see a dolphin or two if we got lucky. We ended up seeing probably 50 to 60 dolphins. We highly recommend this to anybody visiting the Myrtle Beach area! To the folks complaining about social distancing, they were barely over half capacity. If folks are that worried about social distancing, maybe don't take a boat ride with dozens of other people. Yes, folks can walk around, but nobody was encroaching on where we were. Some folks would just walk up to the open middle area or the very front or back.

"Amazing Dolphin Cruise"

Omg!!! Must go!!! Highly recommend!!! Dolphins everywhere!!! Saw sharks and jellyfish too. The captain was funny and very knowledgeable. No social distancing but if you want to there was extra space to move around. They didn’t fill it all the way up. We weren’t too worried. People kept to themselves and all of our kids from 17-5 loved it. They know just where to go and made sure everyone was able to see all the dolphins (which came up pretty close to the boat) can’t say it enough. SO AMAZING!!!!!

Amazing trip!! This is the third dolphin trip I’ve been on and this is by far the best one we’ve ever been on. It was like two trips in one. We saw a ton of dolphin and then we got to watch a shrimp boat do its thing. The captain threw over some things he caught and the crew on our boat explained to us what we were looking and and we could touch them. We got to touch shark! Everyone loved it, from the 11 year old to the 40 somethings. Well worth the money.
