Carrying loaded boats using correctly placed slings will place less stress on the hull than paddling steep, short chop. If the seals are that weak they are going to fail anyway. A trolley should be placed just about under the aft bulkhead. Also says a lot for wooden boats - you can abuse them and there won't be any bulkhead damage if correctly built.

Try walking back and forth a couple of hundred yards and tell me it is faster than loading beside the vehicle!!!!! And as for dragging it, you can place its bow in the water before taking it off the trolley. Use a trolley. [Jim et al] > Do some tides change faster than others? Yes as the height of tides varies throughout the world, and generally needs to "go the distance vertically" in 6 hours (low to high). Slower would definitely be the answer where there is only one tide a day. The "tide speed" should actually/could refer to the beach slope angle too. The rate of rise and fall varies during the tide cycle as it is in its purest form, a sine wave. Again that varies throughout the world. Have a look at some of the Japanese tides and you'll see what looks like 2 frequencies a little out of phase and differing frequency over a few days. The rate will also depend in any one place on whether it is a spring or neap tide. Check the height of a tide in the Bay of Fundy (40 feet?) and apply that to a gently sloping beach for "drag distance"!!!!!!
