Pax - The only down side will be if a panel rots away too quickly during crabbing season - crabber will bitch to no end ( can not blame him ). Crew forgets to change the panel - it can happen.
Our bay water salinity changes year to year - that can slow or hasten corrosion of panels.
The trotline rigs are OK but have drawbacks. I've seen boats snag anchors on them and bottom fishermen can lose hooks to them.
This adds a serious danger to crabber as a 2 - 5 oz weight comes flinging into the cockpit.
The dark floats are visible on cloudy / rough days but when do most pleasure boaters go out ?
Ghost pots is a tough problem to fix - no one simple answer. Crabbers move gear a lot so any type of semi permanent anchoring is ruled out. Larger floats would help but could drag pots away.
One good thing - the new side scans do make finding lost ones much easier.
What could be more mundane than dying of old age or of natural causes when there is death by misadventure to be pursued ? Skip
