Hey. Moving it 4ft was huge! If you can go 4ft you can go 400ft with patience..
- Don't think in terms of getting all the way in one go. Think in terms of 4ft and then another 4ft.
- Based on the pictures, the high tide isn't going to do you any good until you get the boat another 10ft closer to the water - maybe 20ft -- until the high tide level is about 12" deep to start floating the boat a bit. Until you get that far, it's probably easier to work at low tide.
- The people who keep saying sleds probably haven't tried it. Mud and sand is not very slippery if a lot of weight is on it. And the plywood will tend to dig in at the front and even create a suction. Think "tracks" not "sled". Get some 2x6's (2x10's would be better but probably expensive). Grease them really well with trailer bearing grease that won't wash off. Jack up the boat and put a board under the boat topsides and one under the keel. Line up another two boards straight ahead. Pull the boat onto the 2nd set of boards, then pick up the ones behind and put them in front. Just keep swapping the boards forward as you go. If you are using 2x6's you may want to screw two together to make a 4x6 so it doesn't flex too much - or screw together four 2x4'. If the boards flex, then you will be pulling the boat "uphill". Have some cinder blocks or flat rocks to hold the boards under the water when the boat isn't on it.
If it still doesn't move because the curve of the boat puts the weight on only a few inches of track, grease a 3ft piece of board. Sand a curve into the front of the board so that it won't dig into the track. Put that between the track and the boat. Then attach the come-along to the 3ft board and pull that with the boat sitting on top. Use more grease than you think you need
- Get a 4 ton come-along. They're only about $50. If the anchors are gone just try banging a metal bar into the mud with a sledge. Do it at an angle like a tent stake. Depending on the mud this may not hold - you may need to get an anchor - but it's worth a try and is cheap. You might find someone who will loan you their anchor.
- More weight on the mast would eventually get the keel up but that is an old boat and old rigging. When it was new, you could have put a thousand pounds on it, but it's probably not worth the risk. Just put the track under the keel. But once you get the boat partly floating, it will take much less weight to hold her over. The keel will then become a real problem because it needs 5ft deep water. So hold onto that trash can for the 2nd part of the trip.
