Not at hard as it seems or some make it sound. I assume all of the wood is out of the boat. If it is in decent shape you won`t need to remove the old varnish, simply sand it smooth and feather any areas where the old varnish has peeled. I probably would use 120 sandpaper on the old varnish. You need a warm relatively dust free atmosphere in order to varnish. Use a good quality one part marine varnish. Thin out the first coat about 10-20 per cent. sand with 220 paper, Just scuff sand, to rough up the surface, and remove any dust. Important to use a tack cloth after wiping off sandpaper residue with thinner. Wait at least 24 hours between coats. Sanding should not take more than 1/2 hour per coat. Try four at least 5-9 coats. Remember to strain varnish between coats with a funnel strainer, and use a good quality bristle brush. An easy way to varnish both sides of a board at the same time is to take a piece of plywood the size of the board to be varnished, and drive 2" drywall screws at each corner. then lay the board on the screws, Now varnish the flat surface area only of the board, and flip it over, on the screws and varnish the other flat side. Then with a relatively dry brush, brush the edges. Don`t put a heavy coat on the edges as you will have to sand off the runs after it drys.
