A full metal hull should do that. But don't forget about the mast top VHF antenna and the other wires going up there. There needs to be lightning arrestors on the antenna feed line and also on the power wires going to the lights. Else the surge will just come in through there and spread in to the whole electrical system.
As for the wheel and tiller, they should be electrically connected to the ground that the mast uses. This ensures that everything is at the same potential and there isn't a different voltage at your mast, rigging and lifelines than there is on your wheel or tiller.
