The northern part of Phang Nga Bay includes all the islands and coastline of the bay to north of the island of North Yao (Ko Yao Noy). 42 islands in the bay are included in the Pang Nga National Park. The sea in this part of the bay is turbid (not to be confused with "dirty") green in color due to the many rivers flowing into the bay from the mainland and carry small particles of mud. Many islands and rocks of unusual bizarre shapes make yachting in this region very interesting. The most popular place here is James Bond Island and the village of Sea Gypsies. It is not only yachtsmen who get here - many tourists are brought to James Bond Island on longtails - long narrow Thai motorboats. However, the real hallmark of Pang Nga Bay are mangroves and the so-called Hongs - potholes in the rock islands, at the base of which either water or sandy bottom or clay swamp with mangroves. Many hongs are accessible only through caves. At high tide, some of the caves are flooded and visits to some of the hongs are only possible at low tide.
The north of Phang Nga Bay is difficult to sailing because the depths there are very shallow. However, a large part of the bay is accessible to travel by yachts.
It should be noted that the wind statistics below are from Phuket airport, the closest place we have wind data for. In the bay itself, the wind is much weaker and there is almost never any waves.
Yachts for a trip to the north of Phang Nga Bay you can be rented on Phuket at Yacht Haven Marina. Monohulls and catamarans are available for rent.
