hi i would highly recommend the mermaid 1 or 2. Mermaid 1 does 9 day trips mermaid 2 does either 3 or 4 day trips. Both boats are STEEL not wood boats. The boats are very comfortable at sea even in rough weather. I have been on both a couple of times. Food is great and the boats are very well laid out. Mermaid 2 does similian trip for 4 days and south of phuket for 3. Do one or both as the sites are different.
