Beberapa lokasi penyelaman terbaik di dunia hanya dapat diakses dengan perahu. Pada suatu saat dalam karier menyelam Anda, kemungkinan besar Anda akan menaiki perahu untuk menyelam. Berikut ini beberapa tips untuk membuat penyelaman dengan perahu Anda lebih aman dan menyenangkan.
Perhatikan
Awak kapal akan memberi pengarahan kepada Anda dan sesama penyelam sebelum atau segera setelah Anda naik ke kapal. Selama pengarahan ini, mereka akan membahas bahaya yang khusus terjadi di kapal serta tempat yang tepat untuk duduk, berdiri, dan menyimpan peralatan Anda. Hal ini penting untuk meminimalkan risiko terpeleset, tersandung, dan kecelakaan lain saat kapal meninggalkan atau mendekati dermaga atau bermanuver.
This briefing will also cover emergency procedures and include the location of the oxygen unit and first aid supplies. It’s entirely appropriate for you to ask questions about the emergency procedures or to ask to inspect the oxygen unit. A dive operator who prioritizes safety will be glad to show that their oxygen and first aid supplies are clean, organized, and in working order.
The dive staff should also present a briefing of the sites that you will dive. In addition to covering points of interest on the sites, site briefings will also cover entry and exit protocols, depth, expected visibility, descent and ascent protocols, and possible hazards such as currents. Importantly, they’ll also cover the recall system, which the vessel will use to signal all divers that an emergency has arisen and to return to the boat. Common recall systems include revving the engine or banging the ladder with a wrench.
Pastikan untuk memperhatikan selama pengarahan kapal dan pengarahan lokasi.
Di atas kapal
One general piece of advice that’s useful on boats is “one hand for yourself and one for the ship.” This serves as a reminder to maintain three points of contact with the vessel. In general, it means holding on or having a free hand to grab a rail in the event of an unexpected bump or slip.
If you are prone to seasickness, be prepared to manage it. Use anti-nausea medication according to the package directions or your doctor’s instructions, but make sure you’ve taken it successfully on land in the past before you go diving with it. You’ll want to know that it controls your symptoms effectively and doesn’t cause any side effects that may impair your ability to dive safely.
Di Dalam Air
Jika Anda naik dari penyelaman dengan menggunakan tali tambat, carilah teritip, hidroid yang menyengat, dan pertumbuhan yang berpotensi berbahaya lainnya. Hindari memegang bagian tali tersebut, atau pastikan sarung tangan Anda sesuai dengan tugasnya. Jika Anda melakukan pendakian bebas (tanpa tali), gunakan gulungan dan pelampung penanda permukaan (SMB). Ini akan memberi tahu kru kapal selam Anda untuk mengawasi lokasi Anda selama pendakian. Hal ini sangat penting terutama dalam arus dan laut berombak, yang dapat memisahkan Anda dari kapal atau membuat Anda lebih sulit dilihat. Selain itu, SMB akan memperingatkan pelaut lain tentang keberadaan Anda, sehingga memberi Anda perlindungan terhadap cedera akibat tabrakan kapal.
If the vessel uses a live-boat pickup (in which divers board the boat from the water while the engine is running), be sure you understood the crew’s instructions during the briefing, and follow them carefully.
The end of a dive involves hazards including moving ladders, heavy seas, spinning propellers, and divers slipping back into the water on top of the next diver waiting to exit. The crew may ask you to hold onto a tagline as you wait to board the boat, especially if there’s a current. Doing so will prevent the divers from being spread out all over the place. As you exit the water, give the diver in front of you plenty of space. Take a moment to look at the ladder and identify hinges and pinch points, and place your hands carefully to avoid them. Keep your regulator in your mouth until you are safely back on board.
“There is nothing — absolutely nothing — half so much worth doing as simply messing about in boats,” wrote Kenneth Grahame in Angin di Pohon-pohon Willow. Ingatlah tips ini, dan nikmati tahun-tahun menyelam dari (dan bermain-main di dalam) kapal.
