GA for the dive boat Summer.

To be an accomplished diving master in Thailand with access to both the Andaman Sea and the Gulf of Thailand would be about as good as it gets. But it is one huge step up the joy register to own your own diving support vessel. This is especially true if you can also accommodate 30 fellow divers and a supportive crew of eight to cater to the divers’ needs and navigate the vessel.

That will be the situation for one man when his new 28.8 by 7.5-meter boat will be delivered from MITS Decisions shipyard in Samutsakhon, Thailand later this year. In early April the sleek craft was already taking shape at the yard. The vessel’s main propulsion engines, a pair of 400-HP Cummins NTA855-M, will be mounted aft and will turn up to 1800 RPM into 4.9:1 reduction gears to turn propellers with diameters in the 57 to 58-inch range.

A pair of Cummins 6BTA-powered generators will meet the vessel’s extensive electrical needs including two 8 HP aircon units. In addition to 22 single and double bunked staterooms for guests and crew, the dive boat will have six heads. Guest cabins will open onto spacious side decks. Spaces on the upper decks are set-aside for dive equipment stowage and air compressors for recharging tanks. A RIB can be launched by crane over the stern from the upper deck aft. A large swim grid is provided for the convenience of divers.

The dive boat is to be named Summer which is appropriate for the year-round summer climate of Thailand. It will move between the Gulf of Thailand and the Andaman sea on Thailand’s west coast in turn with the seasons when diving is best in the two locals.
