I'm not a boat mechanic but this is how I split my 1986 Smoker-Craft Avanti Deck boat. Unhooked EVERYTHING that connects from top of boat to bottom, pulled rubber out of the bump guard, pulled all the screws out of the trim, pulled about as many screws out that were under the trim (I have a feeling someone's split that boat before and never fixed anything), started with a wedge of 3/4 plywood to hold it apart at the corners, worked in two landscape timbers as cradles (it's what I had laying around), put blocks next to the upper hull to keep it from spreading out, hooked a HF chainfall to each corner and lifted slow. It's not as scary as it looks. If manufacturers made large plugs where you could jist unplug your electrics like the forewall plug in a truck the whole provess wouldn't take but an hour. If I had it to do over again I would put a board on the oitside of the landscape timbers connecting front to back. Would make for a more secure cradle since my lifting points aren't moveable so they aren't right where I wanted them.
