Ini summary dari pengalaman boat diving di area ini, sebenarnya banyak point bisa diaplikasikan untuk daerah lain juga. Selamat membaca.



1. If you’re prone to seasick during a boat ride, take seasick pills at least 15-minutes prior getting onboard. DRINK ENOUGH WATER.

2. ALWAYS USE SHORTS (hey you’re on the beach, what’s with the pants?), sandals is preferred. Boats depart from non-jetty beach, which require you to walk on sands and knee-deep water to get to the transfer dinghy or to your boat.

3. Make sure all your carry-on items are secured in a dry-bag, don’t put anything inside your shorts’ loose pockets to avoid it from getting wet at knee-deep water or from breaking waves on the beach.

4. Do not bring your dive gear in big-sturdy travel bags or those square plastic boxes on board. The space inside the boat is very limited. USE MESHBAG. Some dive shop may lend it for free. MAKE SURE YOU HAVE YOUR NAME ON IT to avoid confusion from the porters/crew during the loading/unloading process at the beach.

5. Always make sure your FEET AND SANDALS ARE FREE FROM SANDS before get on board the dinghy/boat. Lean and hold on to boat side, dip one foot at a time into the water before set it onboard. Sands ruin equipments, and it’s messy.

6. The transfer dinghy from the beach to the diving boat is very unstable. Make sure you SIT STILL DURING TRANSFER and not moving around from side to side.

7. When the dinghy gets to the side of your diving boat, hand over any bags/cameras to the deckhand or captain, BEFORE YOU STEP IN. Again make sure no sands on your feet. Most boats have narrows area for entering, so make sure you grip on something, or don’t hesitate to receive the crew’s extending arms for safety.

8. When you’re on board, place your personal non-gear bag in a secured area. Do not scatter your things around on the bench, THINK OF OTHER PASENGGER’S COMFORT. During the boat ride, things may fall down / tip-over if you place them recklessly.

9. Ask the crew where the driest/safest area of the boat, in case your items or camera need to stay secure or dry. Some boats cabin can be very wet during a rough surface ride. Camera housing may rollover if not placed properly.

10. Right away CHECK YOUR DIVE GEAR PERSONALLY, EVEN IF IT’S RENTAL! Make sure your gear are correct and completes on-board. If something is missing/broken, you’re still near the shore, the crew can still recover whatever item need to be replaced from the beach/the shop.

11. Most of the time, your gears maybe assembled by the boat crew. They are trained to do it, but you know your preference better, so always DOUBLE CHECK your set up personally.

12. When your BCD & Regulator are secured to a tank, make sure your fins, booties & mask are secured and wrapped inside/on the BCD. This to make sure you have everything you need, and to save space inside the boat. Fold your empty mesh bag and place it underneath the bench. THINK TIDY!

13. With a full-capacity boat, most of the time the Divemasters will ask you to PUT ON your exposure suit until waist high just before departing. This is to avoid:

- Wetsuits piling up on the bench or gear-up area and picking the wrong suit. Many wetsuits are alike these days, especially when you rent it from the shop.

- A good practice to put on your booties too, for extra padding for your feet absorbing a bumpy ride, and to avoid slippery.

- Seasick. When you put your wetsuit on the dive site, the boat is may be rocking from side to side while suiting up inside the cabin. Also to avoid delay on the dive site. Getting in a wetsuit can be a hard task for some.

- In an unlikely even the boat is tip-over by a big wave, everyone is positively buoyant with wetsuits already half on.

14. Make sure you use the toilet on board when the boat is stationary, before departing is the perfect time. Most toilets are at the front side, the most rocking part of the boat during a ride.

15. LISTEN to your Captain or Divemasters briefing/explanation about the boat rules and safety equipment.

16. Be social. Introduce yourself to other guests on board, recall their names clearly. You will spend the whole day diving with them, through any fun or emergency.


1. Pick your stationary spot. If you like the sun, ASK for Captain / Divemaster’s permission to sit at the very back or on the roof (if surface is flat).

2. For those with seasick problems, avoid sitting inside the cabin with limited view outside. Try to sit at the back, where the fresh air is. Avoid looking inside the cabin too much, or starring to the hand phone or book if you’re not used to. As much as possible set your eyes to the horizon.

3. Observe and pay attention to the boat layout and its safety equipment, simulate your dive preparation and any actions should there be any emergency situation arises.

4. Do not extend arm or foot or any equipment (especially to wash your mask and snorkel) when the boat is cruising to avoid hard splash entering the cabin. The impact may cause you lose your mask/snorkel (happened so many times).

5. Scan the water and horizon. You may see dolphins or whales or flying fish at distance, and it always a good feeling to be the first who notify the whole boat and share the view, right? Some guests may have never seen them before.

6. Sleep if you need to. It may reduce your discomfort during a ride.

7. Keep your thing and space tidy at all times. Keep an eye on your camera during a bumpy ride. Do not rely on the boat crew to do it for you, they have other important tasks to conduct.

8. Be careful when hanging towels, clothes or rash guards to any railing. The may be blown away by the strong wind unless you knot them.

9. Do not let any unused plastic bag sits on the bench or on the floor. They get easily blown away too, even if they’re inside the boat’s cabin.


1. By the time you get to the dive site, WATCH & LISTEN CAREFULLY to Divemaster’s briefing. DO NOT MULTI-TASKING DURING A DIVE BRIEFING (preparing your camera, defog your mask, putting on wetsuit, etc) as you may get the information partially, and this may lead to potential problems underwater. A good and strict Divemaster will often repeat and ask for your understanding, should he/she sees you doing other things during the briefing. He/she’s not being rude, just to make sure all divers in the group are aware of the dive plan.

2. Anything in the dive briefing is not clear to you, ASK & CLARIFY. Do not pretend that you already know and can handle the diving by yourself, especially if this is your first time diving on that particular dive site.

3. At the site, make sure your group gear up at the same time. If you have more than one group on board, your Divemasters will split the groups into separate preparation. If space is limited, make sure the first group to dive have their space. DO NOT BLOCK OR STANDING IN OTHER GROUP PREPARATION AREA, stay clear of the back of the boat or the entry area.

4. Equipment double check→ Buddy check.

5. BE QUICK AND EFFICIENT. Do not let your group member wait too long for you at the surface, especially when current is presence, or rough surface. Again, gear up at the same time. A good Divemaster will monitor this timing closely for a perfectly planned entry.

6. Make sure you wash your mask after defog it on board, NOT AT THE SURFACE. For some beginners, this will take up some time to remove and replace the mask back to their face, current may push you out of the intended entry point already.

7. Types of Entry for Drift Diving:

A. Normal Entry with Current Line: the crew will deploy a current line behind the boat, normally a minimum of 15m long.
Enter the water with positive-buoyancy (not less than HALF-FULL BCD), immediately find and hold on to this line. STAY CLEAR FROM THE ENGINES. Until all divers is in the water, then the Divemasters will SIGNAL the group to deflate BCD and descend at the same time.

B. Negative Entry: everyone line up at each side of the boat with EMPTY / DEFLATED BCD.
At the Divemasters count, divers from the same group ENTER THE WATER AT THE SAME TIME (No Delay), and immediately orient yourself, swim down to drift or find the planned dive site. YOU SHOULD NOT HAVE EQUALIZATION PROBLEM with this type of entry and be prepared to kick hard/continuously should you need to fight the current to reach the intended reef/rocks/pinnacles.

8. Enter the water (Back roll or Giant stride) only when you get the CLEAR SIGNAL from the Boat Captain and Divemasters. Clear means:
- The boat is at the right position of the entry point.
- Water surface and below are clear from divers or corals/rocks/mooring line/any hazardous objects.
- Boat’s engines are turned idle or turned off.
- All your equipments are tucked in, nothing getting stuck on any part of the boat.


1. Area with heavy boat traffic like Nusa Penida, deploying a Surface Marker Buoy (SMB) during or after a safety stop is mandatory. Always prepare your own SMB and know how to deploy it properly. Don’t rely on the Divemasters, in case you get separated underwater and have to surface by yourself.

2. Most of the time, condition is ideal when group is staying together with the Divemasters during safety stop when he/she deploys the SMB. Finish your safety stop/deco stop accordingly, and surface near to the SMB.

3. A good Boat Captain will monitor the dive timing based on the Divemasters briefing & dive plan, and manouvre the boat according to it while observing bubbles & current change.

4. Deploying SMB will also cut pick up time at the surface, as the boat may have seen you earlier and approaching closer before you surface.

5. Near the end of your safety/deco stop, SWIM OUT TO SURFACE OF DEEPER WATER, away from the reef/shore just before you surface. If you surface at water too shallow where reef and rocks are, the boat can not get there to pick you up, with current/waves pushing the boat inward to shore constantly.

6. Always watch which way the boat is approaching toward you. STAY CLEAR FROM THE ENGINES.

7. STAY ON THE LADDER SIDE AT ALL TIME, some boats have grip line for divers to hang on to while waiting for their turn climbing the ladder. Also the deckhand and Captain can maintain a clear sighting of all divers in the water, in case he needs to reposition the boat or reversing, when it’s to close to reef/shallow water.


8. ALWAYS HOLD ON TO THE LADDER while removing your weights and BCD and hand them to Deckhand. FINS ARE LAST to take off.

9. If diving in a big group, it is advisable to CLIMB WITH ALL EQUIPMENT ON if you are comfortable. Hand out your fins first this time, and climb. This is to save time, not letting other divers waiting too long at the surface.

This method also applies when the SURFACE IS ROUGH and all divers need to get on board IMMEDIATELY:
• Always be careful with the rocking ladder or boat undersides during a rough surface pick up. When you’re still at the surface, DO NOT GET UNDER THE LADDER, maintain a clear safe distance, or stay at its side until you can manage to grab it and climb.
• During exit on a rough surface or very smoky boat engine, you may want KEEP YOUR MASK & REGULATOR ON at the surface and while climbing the ladder.

10. When a diver is climbing, STAY CLEAR OF THE LADDER area until this diver is on board. In case the diver slip the steps and fall back down, he/she will not land on you!

11. When you get onboard, MOVE AWAY FROM THE LADDER or the back of the boat. DON’T BLOCK the way for other divers to climb in the boat.

12. FIND your assigned tank spot and disassemble / reassemble your equipment there. AGAIN, KEEP ALL YOUR HOSE & DIVE GEARS WRAPPED INSIDE & ON THE BCD.

13. When diving trip finished, pack your equipment back in the mesh bag. Some boat crew may do it for you, but it’s a good practice to do it yourself, make sure all your gears are in the bag. Returning back to Sanur in late afternoon, condition may be choppy compare to the morning departure. So it’s good to have your equipment stored neatly in the bag.

14. As much as possible, FLUSH your wetsuit during a safety stop: While maintaining head down feet up position, blow bubbles momentarily (orally or regulator purging) through your wetsuit collar.

15. If condition favorable while you’re still at the surface (less divers, calm surface), after handing out your BCD/Tank, unzip your wetsuit and pull it down to their knees, FLUSH IT. You may do this while holding on to the ladder, or when many divers still need to remove their gears, swimming away from the ladder with your fins still on.

16. On a calm surface, if a diver reluctant to use the toilet, ask the Deckhand to lower the ladder by the side of the boat, jump in the water, hold the ladder, and urinate there. Remember: Your wetsuit must be rolled down to you knee! Peeing while wearing a wetsuit fully may cause the liquid to be trapped inside wetsuit and booties, and leak out when you’re inside the boat. SMELLY BOAT!
