I was very puzzled to find it gone.
I am familiar with that sense of puzzlement.
Years ago I permitted a battered Wards Sea King aluminum canoe for use on the reservoir a few miles from our home. It required a $60 permit and agreement not to use the boat elsewhere (zebra mussels and etc invasives), so a good use for a beater.
I took the Sea King up to the launch a week after the season started. There were already dozen of boats chained to a rail, mostly Grummans and Colemans, but also a few decent RX canoes and even a few composite hulls. Some of them where secured with decorative plant hanger chain or $3 combination locks.
I secured Sea King with a beefy-arsed chain and a big Masterlock.
Understand that the Sea King was a beater, dented all to hell (ah, the memories), slightly hogged from a pin (more memories) and covered in grunge from long disuse.
I went back to the launch a few days later with my sons to take the Sea King out on the reservoir.
Well, it was right there. . . . .wha, huh, where. . . . wander the launch shoreline in disbelief, looking at far nicer canoes with far lesser chains. . . .wha, how, I don’t understand. . . .no canoe, no lock, no chain. WTF?
Gone without a trace.
You would think I might have learned my lesson, but a few years later I permitted an ancient poly canoe for the reservoir, a “Whitewater” brand. Made, of all places, in Iowa, and certainly not a whitewater canoe; giant recurved stems and a protruding keel that ran not just the length of the bottom but up the stems and down the oversized molded deck plates.
The single layer poly hull was badly UV degraded, but I thought it would still make a gentle use reservoir canoe.
I chained the bejusus out of it and came back a week later to find that someone had apparently tried to run across the bottoms of the row of overturned canoes. Until they came to the Whitewater, where they punched a foot sized hole though the bottom and shattered the molded gunwales. It might have been worth it had I witnessed the act.
Running across the tops of plastic objects may be a Maryland thing.
