Hi Alan, I picked Sunday early because the winds are SW 5 Km per hr and rainy.  Also the tray is 60 lbs and is only pulling the  rope down and unspooling the rope.  I think there is little chance the tray will tip from waves.  I will bring spare weights just in case.  You have proven me wrong before!   The problem with an anchor winch is it is hard to estimate pulling force and the rope could break or the HP valve could activate sending the sub up fast and possibly hitting the boat.  The weight is from drag, not actual weight, when I am pulling it up it will coast if I stop and it is heavy to get it moving initially.Hank

 Thanks Hank,beautiful lake. What about buying, making or borrowing an anchor winch?You no doubt had something similar in your rov days!The thought came to mind that if it is slightly rough the bobbing action of the boatcould cause your drop tray to release. Or are you using a separate line for that?Cheers Alan

First test was all good, Elementary 3000 tows nice and strait but slow.  It took me 1\2 hr to go about 1.5 -2 miles.    The launching of both boat and sub is also good except I need to make a small change to the front roller the boat sits on, it is to high.  The only tough part is installing the 30 hp motor while the boat is in the water.  I have to take it slow and it is kinda heavy.    I have to install and remove the mother each time I launch and retrieve.I am going to rig up a slide so that when I pull on the rope to retrieve the sub, a tray will tip out the weights that make it sink.  Then the rope will pull on the valve mechanism in case the sub has taken on water weight.   It is pretty hard on the hands pulling it up with such a small line, even with heavy welding gloves on.  This way it will come up on its own.Hank
