MSY Seahorse


May 2024

We joined the 11-day Ternate-Sorong cruise on the MSY Seahorse. The wooden dive vessel is built in traditional "Pinisi" style, but unfortunately the masts are mainly deco, there are no sails and the ship is powered by engine only (there are old photos that show the ship with sails). When the ship is not moving, the engine is off and there is only a quiet humming from the generator and we slept well in the comfortable cabin. The very dedicated crew is always friendly and helpful, the dive guides are really good and find the smallest things. The daily schedule is pretty relaxed, there is no rush between dives and meals. When we learned that the area where we were supposed to go during the second half of the cruise had very restricted underwater visibility, the crew showed great flexibility and changed the route to take us to dive sites with way better visibility. This cruise that takes you to some of the best diving within the coral triangle is highly recommendable!

Of course, first of all, the diving/dive sites. The equipment I rented was good and the dive guides as well. Food was incredibly tasty (for sure I gained some weight). The staff was always nice, friendly, helpful and funny. They made this trip perfect with little things like asking how I slept, how the dive was, by making jokes and being happy. When you see, the staff is having a good time and love doing their jobs and it makes you feel so comfortable and welcomed. I was smiling and laughing all day long. Akim did his job seriously and everything was always so well organized and went smoothly. Akim was also joking around and smiling a lot which created a very easy going and comfortable atmosphere.

A big thank you to this unique crew, who with tireless enthusiasm, charm, openness and humor managed to make this trip an unforgettable experience. The organization was top-notch, the food was excellent, the boat was generously equipped, friendly and clean, the cabins were bright and immaculately maintained, the crew was always warm and friendly. Philippe organized everything perfectly and was actively supported by his staff, who accompanied the dives and everything else safely and competently. We weren't always lucky with our sightings, but the trip was still an absolutely remarkable experience, and we grew very fond of the crew. If the journey wasn't so far, I would come back immediately ;-)

MSY Seahorse is an amazing and especially beautiful boat that fulfills all your expectation. The air-conditioned cabins and bathroom are cosy and have enough space to store your belongings. The sundeck is the place I've spent most of my surface time. It was so nice and relaxing. The food is incredible delicious and also the snacks are always so tasty. They even provide massage, which is so good I took one every second day. The crew is a very good team. Most of them are working with Wallacea since many years and you can see, they know each other very well and have a good spirit. They are always in a good mood, laughing a lot and make you feel comfortable from the beginning. It's like a big family. Nico is the best cruise manager I've ever met: polite, calm but also funny and he always puts safety first. He has an impressive knowledge about the marine life and the enviroment. You'll get caught easily by his enthusiasm and motivation. He'll also help you out with anything and give his best to sort out your problem. Also the booking team is very reliable, helpful and friendly. You'll always get a response in a shot time. The whole Wallacea team is taking care of their guests very well. They make sure, you're gonna have an awesome and unforgetable time on your lifeaboard trip with them. Terima kasih guys for everything, I enjoyed it to the fullest and hope to dive with you soon again.
