We care deeply about your experience – we can’t blame it on anyone else. We take responsibility for your experience from the first email until long after you leave. Wicked Diving is far more concerned that you have a great experience and enjoy your time than we are to try and sell you any trip we can.

About the Boat

Our boat – The Mariner – will serve as your home during these trips. Air-con cabins, incredible food and a massive sundeck, she makes any trip though the Similan Islands a delight. We also have satellite phone, International and local radios, life rafts, life jackets and a crew trained in emergency procedures. If you would like to read more about the mariner, see her cabins or layout…check out her page.

Safety and Medical Info

We try to assure the comfort of all our guests equally. If you have dietary restrictions – we must be notified of this before your arrival. Due to our remoteness, the activities we undertake and, most importantly, the well-being of our guests – we have strict policies regarding health and safety on our liveaboards. Please learn more about these

Prerequisites/Experience Required

While much of the journey does have sites for the beginning diver and snorkeler, Richelieu Rock is in open sea and exposed – so do mandate that every guests have recent diving experience (less than 1 year ago) before joining! This trip is great for the diver, for the snorkeler and for the whole family! Did you know you can easily do an Advanced Course while on the trip? The cost is an incredible bargain and the opportunity priceless!

*The trip price includes: Pick up from your hotel (in the Khao Lak area) – transport to the pier and back – full room and board on trip – Organic Cotton towels and linen – tea, coffee, water and electrolytes – tanks and weights – dive guides – lots and lots of delicious food – good times, great memories and lots of fun on the Simlan Liveaboards

Finally a note about insurance. As always, Wicked Diving and our staff make every effort to assure your safety but there is no way that we can prevent accidents and acts of God. We have continual contact with land and can arrange care for almost any accident or incident that happens – but we may not be near to a facility that can cater to our needs. We recommend Nomads as a very good company designed for these kind of expeditions.
