Does anyone use prop guards on their safetyboats?
If so does it make much difference to manoeuvrability?

We have prop guards on all centre tiller steer boats, doesnt make that much difference, but we are doing a lot more rescues getting people out the water ie raft building, capsized boats, windsurfers, kayakers, than the typical sailing club would do with sailors that are competent.
Not used one on a rib, but performance wise, you might not notice the difference. All depends why you are thinking of fitting one. |

We had a little discussion on this a couple of years back... http://www.yachtsandyachting.com/forum/forum_posts.asp?TID=5993&KW=maib&PID=1058284&title=saftey-boats-prop-guards#1058284
Certainly no harm in resurrecting the topic, given the H & S implications. EDIT; My original link to the MAIB report appears to be dead now, but should still be available out there somewhere.

We got a new rescue boat this year, they didn't fit a prop guard, noticed the three blade prop now has barely two and a half blades..

You all that tough in Kent that limbs can mash a prop up or is it from ramming it up the beach?

The prop guards I've seen don't look particularly good at keeping shingle out.

a)We chew them off with our teeth b)We have muppets that leave the engine running as they charge the beach. One of the above is true. tbh The engine they matched to the boat isn't powerful enough, it's a 20hp four stroke which doesn't quite have the oomph a two stroke has and is heavier, with a prop guard it would be unlikely to get the boat on the plane.

We don't eat too many props this way but if we do it is an accepted cost. I will point out that we only need to use this method about once a month as it is not always that bad.
We did however have some one try to come in the other day with not enough power on and they capsized the rib.

Thank you for the help. We are having similar problems in that people forget to lift the engine sufficiently when approaching the shore. What has prompted the prop guard issue is that the last episode resulted in the prop hitting the bottom and the force was transmitted into the gearbox which was ruined. Result - we had to buy a new engine. Prop guards are more to protect people in the water than the prop. We plan a brief refresher course for all rib drivers before they drive the rib with the new (75hp) engine.
How did you capsize a rib coming into the shore? Edited by Buzz - 25 Oct 11 at 2:20pm |
