“Was looking for a quality day trip with my family and found it! The coastline of Vietnam is amazing and we got to places that none of the other boats could reach! Thanks to the crew of SeaYa who took such good care of us. The food was excellent at the Marina when we docked and the facilities/service there is 5 star and included in the price. We decided to stay for cocktails until sunset - the VIP bus took us back. Would do it again in a heartbeat! ”

“We were looking for something totally different to do while in Nha Trang and our Hotel recommended an exclusive adventure on a one of a kind fast boat! We all had a blast, snorkelling and exploring white sand beaches. The weather was very kind. The service with the crew and the Marina was 100% Highly recommended”

“Having decided to do something completely different for our Corporate weekend we headed to the coast of Nha Trang to have some fun! The crew of SeaYa didn’t disappoint. We were picked up by VIP bus to the Marina and took off (it’s fast) to our various destinations along the coast. This isn’t for the faint hearted as we went for the RIB Adventure which was a huge adrenaline rush for us all! Do it! Your staff with either love or hate you! ”
