In Toronto, many boats , including mine, store with mast up. It's a huge job on a 49 to de-rig every year.
Not sure where the notifications stand.
Hunter just found out very recently, by their customers who saw the notice calling them.
I guess I've only seen the clubs along Lake Ontario that use a crane to lift out, not any marinas with a travel lift. Yes it will be a pain to drop the mast if you can't find anyone willing to do this mast up.
Selden seem to be pointing blame to owners for the failure..... may be a case of CYA.
All the failed fittings origin from long distance cruising boats with inadequate rig tune and long periods of sailing using only the genoa
