Sib Ladders

Locozodiac · 28 August 2009, 16:10

All kind of threads and discussions have been treated here, how about you are in the mood to stop in middle of the sea for a nice summer refreshing bath and, 4 lettered word…, you don’t have a ladder, what would be the “best way to get back on board” as opposed to buy/use a regular aluminum, wooden traditionally ladders found in nautical stores ? What are your experiences, self made ladders on this issue ? Post pics if available.

mmmmm can t visulise that a ladder for a sib? best bet is to ask the divers how they get back in the sibs?

We just "swim" over the tube using the grab ropes and a bit of kicking.

m chappelow · 28 August 2009, 18:34

it has been covered on rib net loads of times in the past ,,but even a rope from bow to stern can give u some thing to get a foot on before it swings under the boat ,,alot of divers even rescue crew use the outboard leg cav plate if its a big enough engine to get a foothold , a lot depends though how fit you are and how you are dressed , if its in the tropics and your in a pair of shorts probley not much effort but if in a heavy or stiff neopreane drysuit / floatation suit or heavy oilskins or clothing / or even with a large lifejacket on it can be hell of a job if you are by yourself,,,we used a scaffolding pole with a few short rungs out from the side then we secured the top part with a line to the opposite side of the boat so it would not swing under the hull when standing on it and that could be used with heavy full face commercial diving equipment ,,,, a lifeline rigged on the opposite tube helps a great deal too ,as most people can get up about as far as waist level then drop back in again because there was nothing to get a hand pull on..,, as an extream last resort you could perhaps deflate a tube a little and crawl /slide on board , mart

Just use the outboard cavitation plate.

If you have doel fins fitted, you're laughing.

m chappelow · 01 September 2009, 12:44

until they snap off ,,with some outboards the cav plates are very thin and when doel fins are fitted it can put a big leaverage on them and it can with some outboards make it easy for them to snap off ,,think you would be ok for occasional use but with a fully kitted diver it could be overload time .

I'll second that, the ones who will be laughing will be the crew when you break the doel fin or anticav plate and cannot climb back as expected, will be usefull to use if you are a skinny chap in water jeopardy. At the present time working on a simple, cheap and very portable solution.

something like a hook over transom,made from tubing and a footplate or stirrup would do ,

spartacus · 01 September 2009, 17:06

A marine grade stainless steel (folding step) fitted to the transom is an option. I've tried to get into my own boat in a wetsuit, and it's not as easy as you might expect. I know Zodiac sell a collapsible ladder, but it's expensive for what it is. Even a knotted rope lashed onto the sponson will provide enough leverage to haul yourself out. I've tried the anti-cavitation plate on the outboard, so that works too.

I use one of these ladders by St Croix. It is expensive but works very well. It can be found here http://www.myboatsgear.com/mbg/product.asp?prodID=1409

Seems to me that it would be pretty high.

If you have fins on, it's pretty easy: Grab the lifeline with your hands about shoulder width apart. Push yourself underwater slightly, in an upright position. Two or three fin kicks should propel you high enough to either do a handstand on the lifeline (where you can swing a leg over), or flop your torso over the tube.

Rope ladders are largely useless; they swing under the boat with any weight on them.

A buddy uses a 3-rung aluminum framed ladder, set against the tube so it stays outward. Doesn't really seem ideal to me, but they do OK with it.

Mine is a custom fishbone ladder mounted on the swimstep.

jky, can you post a pic to see ?

Sharkbyte · 02 September 2009, 23:24

So we've gone from a SIBber going for a refreshing dip in the sea, to a fully kitted out diver.

How about a hydraulic engine lift bolted to the transom with one of those sex slings dangling from it???

Forums, don't you just love em.

telescopic HI -AB crane would be even better lol ,,only problems with forums is that some people with not much experience may get an idea ,and not always seeing the implications , may try some thing only for it to go tits up so best we try to cover all aspects ,,its only food for thought at the end of the day,,,,,, the used pair of doel fins that i bought came of a speedboat with a cracked cav plate coz the previous owner had used one side as a step for doughnutting ,

Ummm, of which?

My friends ladder? Don't think I have a pic of that, and won't see them until at least next weekend (this weekend is a US holiday, and the hotels are expensive where I dive.) Theirs is a 3-rung ladder, which has a slight bend near the midpoint (supposed to follow a hull contour, I think.) They use a kludged rope assembly to clip it onto the lifelines, with the outside of the bend against the tubes. The bottom rung ends up a little high, but they're both little short muchkin people, and it works for them.

Mine is shown in the pic below. (Sorry about the image size, if that's a problem. Wanted to get it at least visible.) It's made of 1" Aluminum square tube, with a 3/4" reinforcing bar hammered into the upper section (well, the bottom center section in the pic.) The mount is a plate with a couple of dog-ears welded on, and a hole drilled into those. The ladder mounts using a trailer receiver pin.

I use one of these clipped to life lines ;

http://www.marine-super-store.com/po...edpartno=29008

It does swing under the boat abit , but I can easily move it from boat to boat & it takes up no room at all.

There is a technique to stopping it swinging under , but a line rigged to the other tube is a huge huge help.

Nick Hearne · 08 September 2009, 14:00

I have the smaller one of these & it works just fine!
