Bernd:
Thanks Stew,

Well, that's the idea, catch it between the hulls. But when the boat is out there several yards (meter's?) it isn't going to be easy. Will have to video some of that for a good laugh, right?

If worst comes to worst you can always install video telemetry? Boy if your wife reads all these ideas that I keep having she is going to kill me. :lol: :lol:

Cheers :beer:

Wouldn't it be easier to put a high-strength magnet in the bow of the boat-to-be-rescued and a thin steel plate on the stern of the rescue boat? Seems like a lot less fiddly way to take the disabled boat into tow. Get close and let Maxwell's laws do the hard work for you.

Bernd:
Ah Marv. Were talking models here and don't need any great speed to get the boat back. Half the fun is in building this boat and then trying to get the other boat. If I wanted to make it easy I would have a small hook on the front of the speed boat and a large loop on the rescue boat that could be dropped over the hook on the speed boat. A lot less weight and I won't have to worry about the magnet letting loose when the water gets rough.

Got a little more done on the Rescue Boat.

In order to mount a frame work over the top you need to secure that to the pontoons or floats. To have a secure mounting in the styrofoam you need to add some wooden blocks, perferably hard wood that will hold the screws better. So I need to make some cutouts in the floats. I marked them on using a felt marker.

Next is to scoop out the foam. Very easy to do if you have one of these:

All you need to do is use some 12 or 10 gauge copper wire formed to the shape you want to cut out. In this case I needed something about a 1" wide.

Of course you don't want to stick the whole iron through the foam so a stop is needed. I made one out of a piece of 3/4" plywood. Cut two slots in to fit over the wire and presto a depth stop.

And here we have the scooped out 1" wide by 2" long by approx. 3/4" deep pocket.

Here are the blocks that are going to be expoied in. They are 1" X 2" X 3/4" hardwood. I ACC'ed small pieces of wood over the top so they would be level with the top of the foam.

Filled the hole full of epoxy.........

.....and dropped in the blocks and taped them down so they wouldn't float to the top.

Next will be a super structure over the top of the two floats to tie it all to gether, but first I need to get the propellers so I know about where to mount the motors. They have been ordered and so have two 6 volt batteries the will power each of the motors. So it'll be a while befor I get back to this project. I figure the items should be here by next week sometime.

In the meantime I can think about what I'm going to use for the superstructure. It's going to be either real small PVC pipe or 1/4" luan. Right now I'm leaning toward the luan.
