Similan Quest is one of the best-value Similan liveaboard diving boats. Similan Quest has a 'flexible' schedule. You can join the boat in the morning on any day, and stay as long as you choose. Most people choose 2D/1N (6 dives) or 3D/2N (10 dives). You need to stay in Khao Lak the night before departure, and you're taken by transfer speedboat from Tab Lamu Pier to the main boat that is out at sea. Although the main boat spends all its time at sea, it does not stay in one place. Every day it's at a new area and for every dive you enjoy a different dive site. Five days of the week it's exploring The Similan Islands. And on Thursdays and Sundays it goes to Koh Bon.
The boat has air-conditioned twin & double cabins, great food, helpful friendly staff and the prices are hard to beat. With nine air-conditioned cabins, up to 18 guests can stay on Similan Quest for its great value Similan diving trips.
Similan Quest is 25 metres long and therefore able to offer safe & comfortable sailing between dive sites. And there is a motorized dinghy to retrieve divers and to take you to the pristine beaches.
The boat has four double-bed cabins on its upper deck, which is where the main dining and socialising area is. On the main deck there are five twin cabins and a large dive platform. There’s also a large sundeck, which has shaded and open areas. Delicious food is served throughout your Similan cruise, and it’s a blend of Thai and western cuisine; tasty, but not too spicy.
All in all the boat is very well designed to offer safe & comfortable Similan diving cruises. The local crew are friendly and helpful, and the international team of Divemasters and instructors are experienced, patient & fun.
