SOSpenders autoinflate in rain?
Bob, I think your comments are an excellent summary of what can be expected and what one should do re: maintenance.
Most boat systems rarely get attention unless performance becomes flaky OR the financial consequences of ignoring the maintenance loom large. This is doubly true of personal safety equipment, which we almost never ''use'', even tho'' we benefit continuously from its presence. All of us tend to overlook the simple truth that an annual inspection and, at the least, bobbin replacement on each of our inflatable harnesses - even if things look OK - is no less important than other critical maintenance items which get that annual attention.
