you can build a homemade steamer out of a long piece of pvc pipe, crawfish type boiler and a duct work to direct the steam into the pipe. takes about an hour or so, lots of info on that subject on the internet.
use some oven mitts to remove it and then a heck of a lot of c clamps to bend it into shape, go slowly
I would use white oak, not the red stuff from the home centers. Also use aluminum fasteners like rivets not stainless. another option is the extruded plastic type lumber, I've seen this and it looks pretty good, especially on a utility type boat.
I've also had good luck resawing it thinner on the band saw, planer, the gluing up a laminate.
