Guest Posted July 18, 2010 Report Share Posted July 18, 2010 A while ago on here after the terrible accident involving a hire boater killed when she fell over the back of her boat suffering injuries from the prop there was some discussion about how such injuries could be prevented. I recall me asking about why could not props be shrouded to prevent contact between the blades and a person in the water but don't recall seeing a reply if the could be or couldn't. On the way back from Zebrugge to Hull this morning aboard the 'Pride of Bruges' I took the following shot of the prop as fitted to her lifeboats - and it got me thinking again why such a shroud could be fitted to NB's ?? Obviously a lifeboat is going to be in a situation where there is potentially a lot of people in the water around it - but it struck me that such a simple and cost effective mod could be universally applied. does anybody know if such a thing would or would not be practical??

Graham Davis Posted July 18, 2010 Report Share Posted July 18, 2010 Wasn't it tried some years ago, but found the be easily clogged by the detrius often found in canals? Link to comment Share on other sites More sharing options...
zenataomm Posted July 18, 2010 Report Share Posted July 18, 2010 I think I'm saying the same as Graham. It's hard enough to get at a serious bladeful without having to negotiate that as well. Link to comment Share on other sites More sharing options...
GUMPY Posted July 18, 2010 Report Share Posted July 18, 2010 Doesn't look like its there for the safety reason, looks like a type of Kort nozzle that directs the flow instead of a rudder. Link to comment Share on other sites More sharing options...
Guest Posted July 18, 2010 Report Share Posted July 18, 2010 Such devices were marketed for outboard motors used on the cut back in the '60's. Don't think they caught on. Link to comment Share on other sites More sharing options...
carlt Posted July 18, 2010 Report Share Posted July 18, 2010 The props on my boat are "shrouded" well, they are in tunnels formed as part of the hull but this is to protect the props when the boat was carrying out rescues in shallow water. I haven't trapped anything in the prop yet but, if it happens, I don't imagine it will be a pleasant task unwedging the offending article. Link to comment Share on other sites More sharing options...

Having worked on cruise ships for many years....and using lifeboats..I can add 'whats missing from this picture ?' Aha......a rudder. Bob Link to comment Share on other sites More sharing options...
Chertsey Posted July 18, 2010 Report Share Posted July 18, 2010 Even if you could easily deal with one of the dangers of falling off the back of a boat, that still leaves drowning, head injuries, getting crushed... Yes, we could also all wear helmets and lifejackets all the time. But the best and only truly effective safety measure is to make sure that you're standing where you can't fall or be knocked off the boat. Link to comment Share on other sites More sharing options...
