Slack Tide

Tuesday, May 11th, 2010

There’s something to be said for shore diving. No boats to wait for, no people to annoy you—you dive when and where you want. Even places you wouldn’t expect (like New York and New Jersey) can have decent shore diving.

If you spend any time reading about shore diving, either from books or the internet, you’re bound to come across the term slack tide, or sometimes, slack water. Slack tide refers to the time between high and low tides, when the tide is changing. That means there are four a day in most places.

During this time the water is relatively calm, because you don’t have excess water rushing away (low tide) or toward (high tide) the coast. This makes it particularly significant to shore divers. In many places, slack tide is the only safe time to scuba dive. Diving any other time and either you can’t enter the water (high tide) or the water will quickly carry you to sea (low tide).

When shore diving a new spot, read up or talk to people and find out if a slack tide entry is considered a must. If it’s not a must, it often turns what would otherwise be an advanced dive with strong current into an easy dive that could even be used for beginner’s certification.

A downside to slack tide is visibility. Calm water means there’s nothing to move particle matter in the water and visibility tends to go down. If you have the option, weigh that into your next shore dive scheduling.

Many websites and weather reporting services give the times of the daily tides. They are very predictable and can be calculated far in advance. Search for your location and terms like “tide tables” to find them.

Shore Diving Tips

Thursday, April 8th, 2010

With two trips to Bonaire, a good portion of my diving has been from a shore. I love the freedom provided by not being stuck to a boat’s schedule. Your dive can be as short or as long as you want, and the only other person that has to be considered is your buddy. Not to mention there are no half-hour boat rides to the dive site.

Shore Diving
It comes with its own set of challenges, though. Waves and surge can be rough, especially with all your gear strapped to your back. In addition, many sites have a variety of rocks, coral, and ledges that have to be maneuvered while waves are crashing against you. It can catch the unaware by surprise.

The good news is a little bit of forethought goes a long ways. Here I’ve compiled a list of tips to improve your experience.

  • Spy out the best entry point. Shore diving entries are not always sandy beaches, and even if they are, there may be unseen dangers beneath the waves.

    If other divers are around, watch them to see where they enter (or exit) the water. Even if they are inexperienced, watching someone else have difficulty lets you know to avoid a certain entry point. Sometimes just a quick look around can help you avoid a nasty entry.

    If you have other resources, use them. For instance, Bonaire divers have a book made for this very purpose. Check for similar resources in your area.

  • Be prepared. Before you get in the water, make sure you and your buddy are clear on the plan for entry and descent. This becomes even more important in choppier water.

    Have your fins hanging over your arm (if using open back fins). I like to strap my mask on the buckle in front of my chest. Alternatively, you could have it around your neck, backwards on your head, etc. The idea is that it is out of your way and your hands are free to grab rocks or break a fall if necessary.

    Try to have nothing dangling from your body. It’s a bad feeling to hear that “CRAAACK” after seeing your expensive regulator smack into a rock.

  • Slow down. There’s no hurry. Rushing an entry can make you tired and more susceptible to stress in the water. It also increases chance of injury. Take your time, breath, assess the situation, and make as smooth an entry as possible.
  • Time the waves. Slowing down gives you a chance to observe the waves / surge. This has two advantages. First, when the water goes out, you can sometimes see rocks and obstacles hidden by crashing waves.

    Second, you get a feel for the timing of the water. It’s not a good idea to advance while the waves are crashing. Wait until the water begins to draw out and follow it. As soon as another wave comes, find solid footing and hold your ground. It may help to bend your knees slightly (lowering your center of gravity) and turn your back to the wave’s impact. After the crash, move forward again.

  • Float as soon as possible. After you pass rocks and other obstructions, and the water is around your chest, try to float with your inflated BCD.

    Take a moment to catch your breath before putting on your fins (spring fin straps make your life easier here). If you are waiting for buddies to enter the water, you have even more time to relax.

  • Try swimming on your back. Swimming on your back is usually not taught (or encouraged) in open water courses, but it can be far easier, and more relaxing for swims out to drop-off points.

    Before you turn over, you may want to check under the water. You could be passing over some great snorkeling sights worth checking out during the swim.

  • Don’t forget your sunscreen. The water entry and swim out leave you exposed to the sun for more time than you think. Take this into account and apply sunscreen liberally. The back of my neck is particularly exposed during these times, so I like to put a little extra sunscreen there.

Shore diving is awesome, and everyone should try it out at some point. It can be hard work, though, so take the time to be prepared, and I hope these tips come in handy for you.
