I have searched but cannot find in the forums what the stock chain type and size is for my boat. I have the stock Windlass and need to replace both chain and rope. Thank you in advance.

Have you considered going all chain? Great peace of mind if you are buying chain

I have but really don't want to put up with the noise the chain makes. I have had all chain previously. Thanks!
 
It's most likely 5/16" and 9/16" or 5/8". But check the gypsy - there may be markings on it. A previous owner may have changed the gypsy. You can also check with Lofrans - either contact directly or the owner's manual... or even just look in your boat's owner's/parts manual. Some chain has markings directly on the links, as well.

FYI, if the wind is blowing enough that the chain is making making noise, you should be using a bridle - which both eliminates the noise and takes the stress off the windlass.

Also... the chain in the picture doesn't appear to be bad, at all. Check the inside of the links for wear, but from what is seen in the pic it looks perfectly fine. Meaning, you may not really need to replace it.

Thank you. I have considered brindle but just don't want to fool with it. My chain is OK, the splice to line is shot and i figure for a few bucks I might as well replace both since they are 13 years old. I will look where you said on the gypsy. Thanks so much!

So to determine exactly what you need, look on bottom of the gypsy with the chain pulled aside and on a Lofrens, there is a stamp code. Mine was 08101. I contacted Defender and they cross referenced this # and provided me with 6 options. They are great.

Another option for you is to simply cut-off a couple feet of the rope and splice it (or have someone local) right back onto the link. You could also look at flipping the rope end for end. Another thing is to take the rope home, once cut off, and put it in a mesh bag and toss it in a front load washing machine, then soak it in fabric softener. Should come out almost like new. If you can find someone local to the splice, they may even do it right there on the boat. Check around the docks... or how 'bout learning how to splice yourself? A little extra work to do it this way, but it's pretty close to free.

Adding to the info you gave about Defender... as Jim mentioned, that code is listed in the manual, as well.

I flipped mine as the end in the locker was like brand new. Cost $20 to get spliced back on.

Not to be flippant about $, the rope is 13 years old, too short (under 100ft.), the splice was shot, and the chain probably has 1,000 or more cycles on it. All the suggestions are great and will do them for all of the reasons noted over time. $460 got me 200 ft of 8 and 20 ft of G4 chain. Seemed like the right thing at the right time. I really thank all of you for your help. This is an incredible forum and I hope to contribute as time goes on. Calm waters.
 
No worries. I think the most important thing is just know your options. Then you can make the decision that is best for you. And, in the end, that's all that really matters. If you were making a dangerous decision, I'd

EDIT: Not sure what happened to my last thought there, but it obviously that wasn't a complete sentence! "...I'd be more emphatic about making sure you were safe, but obviously in this case it's completely a personal preference thing".

Looks like it was "10180". Just so no one else runs off in another direction. Like me. :)
 
Ok if you dont mind me jumping in here on the chain discussion - i have the same vessel '05 420 and all chain. My issue is that she rides bow down and isnt "level" and it annoys the hell out of me! My friend has the same boat with diesels and his is perfectly level at the bow (the attitude), he is chain and line. I have thought about placing weight in the stern but just cant do that. Once she is up on plane all is good, I just dont like that she rides bow low normally.
Am i crazy and OCD?????
thanks

The biggest difference is not necessarily the all chain vs chain/rope... it's the extra weight of the diesels vs gassers. This is just a guess, but I would think he's probably got somewhere between 500 to 1,000 extra pounds in the rear - a google search will probably get you the real difference.

I doubt that converting to chain/rope is going to make much of a difference on your size boat, but an easy experiment would be to simply remove the anchor and all chain and see what happens to your low speed running attitude. If there's no appreciable difference, then you know that converting will be of no help.

-- Do you carry a lot of gear/supplies in the cabin... maybe more than your friend?

G4 chain (which is probably what you have) weighs over 1 lb./ft. No idea what rope weighs. Given the chain is at the far most reach of the opposite side of a lever, it will have a huge affect relative to something much lighter. I think some discussion could be made for diesels producing a lot more torque vs. gassers and that will help bow rise along with more weight in the aft since the diesels weigh more. It sounds like trimming isn't enough of a solution for you. Lazy Daze wrote the test, take it off the boat and see if there is a change, otherwise offload stuff forward perhaps. I would not add ballast in the rear-that would have a lot to do with changing the weight and balance of the original design and IMO a real negative.

The diesels are around 1,500-1,600 lbs each. I'm guessing it's more than twice as much as the gas engine.

Thanks all, and is going to be my plan this summer after the wrap comes off. It hasnt effected the maneuverability of the boat, just the dock appearance and the attitude at slow speed running. Honestly i haven't been around any other gassers and could just be the additional weight of the chain rode at the furthest most bow point AND the lower weight of the 8.1's. I do like having the security of the chain rode but if by removing and switching over to the combination changes the attitude i might just do that this summer.
Thanks everyone!
