Re: Gangplank Ideas?
The quick and easy way might be to buy a six foot aluminum ladder, then screw a piece of 1/4" plywood on top of it as the footing.
Plans for a gangplank...I kind of have to cringe at the thought. I mean, it is two rails, some crossmembers, and something to walk on, and if you need plans for that, you may be best off simply buying one. Like, the ladder plus something to lay on top of it. The ladder will be about the simplest, lightest, strongest piece of fabricated aluminum you can find for the job, and the best way to do it. Bolt two "cart" wheels on the dock end if you want it to roll instead of scrape as the gangway moves. The guys in Ace Hardware or any similar shop can set you up.
