Putting a bag over a propellor

[sailaboutvic]

We placed a bag over our propellor 8 weeks ago when we arrived in the marina knowing the fouling is bad .
We plane to start sailing again soon so we decided it was time to remove it and this is what we found after just 8weeks .On the plus side our hull which we copper coat is 100% clean

How clean was the prop?

What a good idea, I think I'll try that & save getting the wetsuit and scraper out!

The bag jus covered the water hole on the sail drive leg so the prop was well covered ,

That was just 8 weeks you can imagine what it would had been like if the boat stood for six months ,like many will have

6 months up a very fertile Brazilian river

Look very much like some of the boats in this marina, there three fish farms in the harbour here so that's doesn't help .
Last time we was here in 2013 boats was haven't to be towed to the yard, now there a diver and for 150€ he will do some cleaning .
We been putting a bad around the prop for some. Time now , if nothing else it keeps the prop and water I let holes clean .

I have a Moody 31 with a conventional shaft drive. The propeller is well under the hull, aft of the rudder which is hung on a skeg and fairly close to it. Does anyone have any clever ideas about how such a bag could be placed on the prop without needing to go in the water?

A long line that you keep hold of tied to the draw string of a suitable draw string bag (cheap plastic sports duffle bag style thing?) on the end of a pole, when the bag is over the prop pull the draw string. Not sure how you might attach the bag to the pole to enable you to recover it after it's deployed. Might work but easier I'd have thought to jump in with a bag & a bit of string...

That way round doesn't sound very conventional to me...

[sailaboutvic]

Sorry to say there only one way if you want to make sure the prop is totally covered .
That's to get in and use your hands .
Believe me even in the Med , it's bloody cold , so you need a good wet suite with seals around the neck and cuffs

The Lagoon cats have the props aft of the rudders but they are saildrives. It's difficult to visualise how one can do that with a shaft drive,

Sorry, got myself turned round. Of course, I meant forward.

Not going to happen on the East Coast, even if marina regulations allowed it!

 

[AntarcticPilot]

The Moody 31 is very flat bottomed, and you can't reach the prop with a pole.

A long line that you keep hold of tied to the draw string of a suitable draw string bag (cheap plastic sports duffle bag style thing?) on the end of a pole, when the bag is over the prop pull the draw string.

I think you have the same problem I had , which is finding the prop in the first place with all that east coast mud

Entirely understandable since you were contemplating an approach from astern when the propeller would be less accessible behind the rudder. I should have included a smiley...

a 6' x 6' sheet cut from an old sail and string to each corner with some little weights perhaps, sunk under the stern and pulled into place. One of those aircraft red warning tags which needs to be removed before takeoff might be useful as a reminder.

I can just touch the prop with my feet without getting my head wet, great pedicure.

Good idea pete , only if you can't get it totatally covered . With no way of growth getting in there isn't much point as it will still get covered .
This year I want to find a way to bag it in shuch a way that pulling on the end of the rope will release the bag and bring it on board , the beginning of the season is the coldest time to have to get in and ours start around early March , plus I could do with having removing it in case of a problem and we have to move .

I might try this, since our boat tends not to move much between big cruises. Last year I was able to dive to scrape some weed from the rudder, using the transom ladder to anchor myself. I should be able to fairly easily go from ladder to rudder and then reach the prop.
Free diving under a boat isn't something I particularly enjoy though...
