Whale Watching

Although you can observe these gentle giants from the shore – the best way to really get up close and personal with the whales is through a whale watch Private Charter. The most common whale sightings include humpback whales that migrate down from cold waters of Alaska to Hawaii every winter to mate and to give birth to their calves. Maui is known to be one of the best places on earth for whale watching. Join us for the most extraordinary whale watching experience!

If you do one thing in Maui this is the one you should do!
Definitely a 5 star experience! Starting from booking until the moment we came back they took care of everything. We decided to go snorkeling and they know the best spots.The staff were so accommodating, even my girlfriend was happy and she is hard to please. She loved how upbeat Jessica was, the day pretty much felt like we were out boating with friends. We saw turtles, dolphins AND whales. One of the most memorable trips we’ve taken. Thank you guys for your Aloha!

All I have to say is WOW! LOOOOVED IT! Definitely the best day of our trip. This is the nicest boat in the harbour, caught our eye right away. The reservations lady was helpful, they asked us about our preferences on juices and other special requests. We had 6 people in our group, all adults. Wanted to snorkel and go to Lanai, and got to do both!

The crew consisted of 2 people, Captain Rich and Jessica. Both are SUPER friendly and have great personalities. They had fishing equipment and we got to do some fishing, my boyfriend was happy because they took care of the bait and everything. We saw dolphins jumping over a whale! It was so cool, so much closer than Ive ever seen before.

Its BYOB, which was great for us because we usually tend to run up the bar tab, didn’t have to worry about that. They provide mixers and food. It wasn’t just one little sandwich, they had snacks available throughout the trip too. If you want to go snorkeling definitely go earlier, the water was calm and the reef was like something you see on TV in those traveling shows.

When we go back to Maui we’ll definitely be booking with this company again. They truly understand 5 star service. Worth every penny. I would highly recommend to everyone, you will have the best memories and pictures to take home!

We were in Maui the beginning of December and were so fortunate to spend the day on the Sea Monkey ! From the first contact with Karen (who arranged things so perfectly for us) to watching the sun set at the end of our 8 hour charter it was heaven! First and foremost Jessica and Rich made us so comfortable and took such phenomenal care of us…we were never in need for a single thing. Rich is an excellent captain and extremely knowledgeable about the islands and the wildlife. He told us lots of Hawaiian history and he knows every good snorkelling spot there is! Jessica is an absolute delight and we couldn’t have asked for 2 more lovely and competent people to enjoy the day with. I especially enjoyed snorkelling with them.We’re counting the days until we can spend another day in paradise with them both on this gorgeous boat (I especially loved the warm water shower for after snorkelling!). Please please please do yourselves a favour and enjoy a day on the Sea Monkey!Visited December, 2016

We spent Xmas day on the boat with Rich and Jess . It was by far the most outstanding and enjoyable experience our family has ever had in the many trips we have taken to the Hawaiian islands.
From our initial dock greeting by Karen , she set the tone for the amazing service we received on the trip. Great food , whales swimming up to and under our boat , fantastic snorkelling and even good fishing to round out the day made it a truly wonderful Xmas to remember. The entire company deserves a big 2 thumbs up for providing such a wonderful experience for the family. We will certainly be telling our fellow Canadians.

What a day! Prior to our trip we chatted with Karen who made sure we were all set. She greeted us when we arrived, very pleasant, very welcoming. Captain Richard and Jessica took us out, we were interested in whale watching and snorkeling. Within 15 minutes of leaving the harbor we had our first of many private viewing of whales. We saw mama with her calf playing in the water. It was amazing. Snorkeling was fantastic, off the backend of the boat easy off, easy on. Richard was a great guide and shared information about fish and sea creatures. He even removed some trash from the reef floor. What a great steward of the ocean and reef. Jessica prepared a great lunch and took excellent care of us all day. Definitely a do again for us! Jerry and Patrice

We had a wonderful time aboard the Sea Monkey. Everyone was very professional and knowledgeable. Karen worked with us to plan the excursion. Rich was our captain and Tawny was our first mate. They took great care of us from start to finish and we saw amazing views of the Maui coastline. We also saw flying fish, a couple of sea turtles, and rescued a preying mantis at sea. We will make sure the Sea Monkey is on our itinerary for our next trip to Maui.

Had a great time with the Sea Monkey team. We took a 6 hr. tour around Lanai. We saw a lot of whales, got up close and personal to the cliffs on the West side of the island, then had a fantastic lunch and snorkel in a little cove on the South side. The crew took great care of us, Tawny took some pictures of us while we were diving, which were much appreciated. Kudos to Karen, who went out of her way, after hours, to return some glasses that we left on the boat.

Sea Monkey is a beautiful boat, with a fantastic team!

We took the family to Hawaii for whale watching season and a family vacation. After our charter got cancelled due to mechanical issues we walked down the dock and found the Sea Monkey Private Charter. This was a hit with the kids and so much more intimate and comfortable. In fact it was so great we cancelled our plans later that week and chartered again later that week. I would highly recommend. Great crew, nice boat and an amazing experience.

If you want to see a LOT of whales in Maui during Jan/ Feb rent a boat from Sea Monkey Private Charters and have a great time.
We did.
We must have seen fifty whales. It was sensational.

We booked with Karen with just 2 days notice. She was so helpful and polite on the phone, answering all of our questions and making sure everything was set up to accommodate our needs and wishes. Rich was an incredible captain with Emily as our awesome crew. They were both very knowledgeable and helpful. We had our 4 children with us, and Rich and Emily worked to be sure the little ones were just as happy and taken care of as the teens and adults, including snorkeling along with them to help. The boat was very well kept and had everything we needed for a fun day on the water. Rich tailored our itinerary to our interests and did his best to see whales and dolphins as much as possible while still having time to get to Lanai and back. Thank you for an amazing experience. We will definitely call again when we return to Maui!

We had a wonderful time! Your crew was wonderful and the boat in great condition and perfect for a private family outing! We snorkeled a beautiful spot, had whales all around the boat and ended the day laughing and singing to a Maui sunset! We will be back and will use the Sea Monkey again and request the same crew!

Exceeded all Expectations!

Our three generation group of 6 had a wonderful time with Rich and Almarosa. From the first to last moment, they listened to what we wanted to do, suggested activities, and brought us on an utterly amazing 6 h trip. (BTW- Highly recommend 6 h!) We saw whales, swam with dolphins, snorkled off the Lanai coast, had plenty of time for breathingtaking scenic cruising. A lovely lunch on board helped round out the day. My communication with the Sea Monkey leadership was flawless. Highly recommend!

We chartered the Sea Monkey for a six hour private Whale watch, snorkel, dolphin watch trip and it was amazing. The crew was awesome and allowed us to do whatever was top on our list. We watched the whales in the Lahaina bay as we headed over to Lanai. We encountered a large group of Spinner Dolphins off the shore of Lanai and we had an amazing snorkel in a protected bay just off the beautiful shore of Lanai! Beautiful boat that holds up to 6 and a large front deck to sit on! It was pricey, but worth every dollar! We would do it again in a heartbeat! I HIGHLY recommend this charter for a very personal experience where you get up close to the best of Hawaii!

First, thank you Sea Monkey, Capitan Mike and Amarosa (sorry if spelled wrong), they were truly fantastic and took care of absolutely everything. They were especially good with the kids, ages 14, 11 and 9. Karen was also awesome organizing everything on the front end. Everything was set as planned. We were very lucky to see some of the most amazing whales swimming together, splashing and just being whales. Wow, an experience and sight myself, my wife and kids will never forget. Amarosa was also fantastic on our snorkeling tour, helping the kids, showing them things and guiding us around the reef. This whole experience far exceeded expectations and this was not our first time chartering a private boat. The best by far, Congrats to Sea Monkey and their operations. Mike and Amarosa Thank You!!!!

We were fortunate to spend a few hours whale watching on the Sea Monkey. Captain Rich and Alisa were a pleasure and such gracious hosts.We enjoyed a lovely fruit and cheese platter and our beverages were always full. We had a pretty easy time of spotting whales and it was amazing! I appreciated their knowledge of the whales and the respect that was shown to not be intrusive but still be able to witness their beauty. I highly recommend treating yourself to this excursion.We look forward to returning next year with our kids for a longer charter.

Saw a sign on Kanapali Beach that advertised Private Luxury Charter. So I took a picture of the sign and checked them out online. Then I made a reservation for the four of us. 4 hours to do three things. I advised Captain Mike and First Mate Emily that my wife’s favorite thing to do on this planet is to snorkel. I told him my daughter loves whale watching and her friend enjoys general pirate activities. With that we were off. We were treated like royalty from the moment we checked in until the moment we departed. We saw whales, we snorkeled a really long time and of course enjoyed pirate activities. Captain Mike and Emily seemed more like friends than a working crew. It truly was a perfect day and we will be back!!!

This is a first class outfit with a mint condition 31′ Sea Ray. Perfect outing for a family of 5 (kids 10, 8, 4). Within minutes of pulling out of the harbor a gorgeous, giant humpback breached about 100 yards off of our bow (see photo above). Then we rode over to Molokai and checked out the scene, and then back to the west shore for some beautiful snorkeling and lunch. On the way back in we blue-toothed my wife’s iPhone to the stereo and had ourselves an epic family dance party. Could not have had a more enjoyable outing! Thanks to Captain Mike and the Sea Monkey team for making us feel so special. We highly recommend this for anyone wanting a special experience while on Maui.
