Re: [Amel Yacht Owners] Sea water chest

Bill & Judy Rouse <yahoogroups@...>


There is another tool that I made for cleaning lines. Have a rigger make it for you. Use 1 meter of 6mm rigging wire. Have one end blunted and welded so that it will not unravel. At the other end have him use a rigging wire sleeve clamped about 20mm from the bitter end. Splay the wires between the sleeve and the end. Insert the welded end in an electric drill. Push the splayed end into the pipe while rotating with the drill. This probably will not turn 90 degrees without some help, but if it does, you have a solution. You can also use it to push out plastic from inside the boat by using the blunt welded end.

Bill, thank you very much for all your help but the early Amels were early in the evolutionary path. Hull #29 has a 90 degree elbow on the bottom of the sea chest that attaches to a 75mm hose that is "U" shaped and is about 90cm in length. This hose terminates at a ball valve that is mounted on a fiberglass elbow that exits the hull. No way to force any brush down this tortuous path. We first removed all the hoses from the sea chest with the exception of the engine supply as this was only a few cm's from the bulkhead and had no play in it. The sea chest was then unbolted from the bulkhead and moved forward to pull out of the engine supply hose. The sea chest could then be raised and removed from the large supply hose. The large hose was then removed from the sea cock. This hose was completely blocked by spaghetti-like marine growth. These were easily removed and the sea chest cleaned. The only area still to be cleaned is the fiberglasses elbow on the hull. As I said ear lier, a diver cleaned about 20cm into the opening but didn't clean out the elbow. We will dive on it today and remove this growth. 

Thanks again for your time and expertise. Unfortunately, we were so involved we didn't take any photos.  We used a GoPro before starting tat really was helpful in planning the operation.

That is because you need to "login with your Yahoo user name and password to be able to view photos and upload or download files and photos.

I CC'd you of this email and I attached the photo that I downloaded for should login on the website because there are lots of things available there. The dimensions for this tool are for a Super Maramu...maybe you can use this idea and make one to fit your Meltem.

Thanks for your help, much appreciated. I recently joined this group and while I can read conversations, for some reason I am precluded from viewing photos.

Yes, there is a photo for the tool with dimensions that I uploaded. 

Search for "sea chest tools" in Photos on the Amel Yacht Owner's Yahoo website. 

You will find the tool I made that cleans from the top of the sea chest. I used this tool at least 8 times while circumnavigating. A few times for plastic removal, once for jellyfish and the rest for growth. Don't leave port without something to clean this!

The inside of that conduit from the outside of the hull to the ball valve is usually missed during the application of antifouling and, it is perfect for barnacle or mussel growth with the huge flow of water.

I have a '76 Meltem and have recently experienced a blockage below the sea cock feeding the chest. A diver was able to clear about 20cm from the hull surface to where the hose makes a 90 degree bend but was unable to clear further. Any ideas as to clear this last area would be appreciated.
