Hi All,
I am new to owning a trawler, having just purchased a 1982 42' KadeyKrogen. She is a big boat, that does take a lot of windage with a very high bow and lots of area to get blown around. Upon purchasing I noticed that the chain was pretty rusty - up to about 110' (looks very solid after that and it is 5/16" 3B chain). I assume rust up to that point is due to it being pretty old and likely of the 320', this is the part that got the most use. I was trying to decide whether to swap the chain end of end, putting the rusty end where it is unlikely to come out of the chain locker - or was considering getting a chain connector and just cutting off the 110' of rusty chain and replacing. While taking the chain out to get a better look - lots of folks offered opinions. One person said that for a boat that size I needed minimum 3/4"chain, and that 3B was not good enough grade - also that I needed a minimum of 300'.
Thoughts? Opinions? I was always under the thought that 3:1 scope on chain was sufficient and 5:1 in a blow ... this person said that for a boat this size 5:1 is minimum and 7:1 in a blow ... any thoughts on that??
Appreciate opinions
