Why do scuba divers always fall backwards out of a boat?
Sounds like you are referring to the 'back roll entry', and it is usually the easiest way to exit a smaller boat with a low gunwale(sp?). The tank breaks the water, allowing you to slide in, roll over, hover and then glide down, especially if done with no air in bc (don't do this unless you know your weighting is spot on and your equipment is all ready to go). I much prefer it to a giant stride, possibly because back roll usually = 6 pack diving and giant stride usually = cattle boat dive, although there are many exceptions.
Try falling in forwards and you'll know. If conditions make standing entries difficult, sitting entries are the next option.
It's easiest to sit on the gunnels facing in, and rolling backwards is the easiest option from that position. In some situations you might prefer to rotate and swing your legs out over the water, then kinda slide in, but it's a lot of work and your tank might ding a wooden or fiberglass boat.
To keep from pushing the lenses of their masks through their eyeballs.
If they fell forward they would land IN the boat.
Out of a small boat, it's the easiest way. However, in large boats, these days, most people do what is known as the giant stride. Personally, I miss the back roll. To me, it's much easier to back roll, and then twist around than it is to walk around the deck.
There is such a thing as a forward roll entry but you have to be careful your tank doesn't slide up and whack the back of your head as you roll forward. It's much easier to sit on some boats and roll backward than to kneel or stand on them in a position that would allow a forward roll. All the forward roll entries I've seen involved the diver rolling over far enough to still hit the water tank first; in other words they do a front flip into the water. I saw two divers in doubles do a synchronized forward roll from the dock at the quarry one day and must admit the "cool factor" was WAY up there LOL! I mean, how often do you see divers in doubles doing front flips?
Please don't try that if you don't know what you're doing.
I've done it off a boat. Took me a bit to do it the first time, mind you.
Some boats its easier than trying to maneuver yourself around to do a back roll.
We don't. It's not even the most common entry. It is, however, the best entry when diving from a small, unstable boat.
I didn't say it can't be done off some boats because it can but you can't do it off all boats. Standing up on the edge of an inflatable and doing a forward roll would be an interesting entry to watch I'm willing to watch if you're game to try it though :eyebrow:
I have to do a forward roll entry off a platform on one of the boats we dive in West Palm Beach and at first I was nervous to do it, but because of the way the platform is, it's an easy entry. I too like backwards entry (I've done this off small boats in Truk Lagoon and also while on a liveaboard in BVIs). That giant stride creeps me out since I'm afraid of heights... I know that sounds silly, but I hesitate every time!
Make for an interesting video at least.
I love either the back roll or giant stride. Assuming the back roll poistion can be a REAL pain on some boats though. One entry I had to do and did not like was a cartwheel (best name I can come up with). I had to step over a short wall, put my foot on a 2" wide ledge, stand sideways to the water and roll out sideways. I was not a fan and quite frankly will never dive with that operation again...for safety reasons not due to the entry type.
That is why the black ops guys (i.e. DIR/GUE/TDI/etc.) wear a crotch strap.
We call that the Tobermory twist Many years ago it was included in the open water classes at the university because Tobermory was a regular trip. Personally I love to forward roll or do a "Nestea Plunge" (for those old enough to remember what that is) style entry when the conditions are favorable. Haven't gotten up the nerve to try the forward roll with the doubles yet, I'd probably kill myself.
Yes it is in fact a Tobermory Twist....:dork2:.....ever get the feeling you know too much? Maybe when you come up here to do the twist I will try on the flips
I'm kinda creepy huh? :eyebrow:
We dive off the Joseph Simon now when we go. Hubby has been on the Mamie and done the twist but I've only been on the J. Simon, I LOVE the raise/lower platform in the back We're skipping Toby this year for Bermuda :eyebrow:
but, if it is forward; then why bother to roll !!! :hmmm:
