Size of rope, chain and anchor for '06 Regal 3560

Windlass? You'll have to refer to the windlass mfgr. to determine the chain & rope size.
Anchor will depend on what bottom(s) you will encounter.
Anchor size depends on the type of anchor. Mfgr., again, will say the size for your boat, but strongly recommend 1 size larger.
Length of rope & chain also depends on your anticipated max depth of anchoring. Rule of thumb is 7x depth. You'll want lots of extra length, though, for safety sake.

I'm a big fan of going with an all chain rode. My windlass on my 4460 was perfectly fine, but the nylon rope always slipped, as well as the knot where the chain met the rope always swelled and then wouldn't go through the windlass. Typically my wife was up there dealing with this situation as I was at the helm and it was always a source of frustration for her and me, when the windlass would get stuck. Going with all chain rode eliminated those issues. The only issue with all chain rode is when you are in a windy environment, clearly there is no real give to the chain if it pulls tight, so in a really windy environment you'll get some sound from the front when that happens. With the nylon line, there would be some shock protection in the give of the rope. I believe there are options of using some kind of shock protection linked into the chain and tied to a cleat, but I haven't gotten something like that yet since it doesn't happen often.

I probably should have mentioned this but the only other drawback or advantage of all chain rode is that you get about 200 to 400lbs added depending on the thickness of the chain and size of your boat on the very front of the boat. Helps planing, but also is more weight for the boat to carry around. Also, throws off your waterline a little bit for your bottom paint. More so in a smaller boat, like my 33 OBX, than a bigger one like my 4460.

Good to do  50' of nylon rode! We would have done that other than the ss spring loaded paddle holding nylon rode to windlass broke/gone/no longer available so just wen with all chain. Not too worried about a hundred pounds of additional weight on the bow, on the 4160. That is just one  of a pretty gal on the vessel

Good info, thanks! As your basically on the ocean and have some high waves our situation is different. On a fresh water inland lake (about 25 miles long) hardly any wavers over a foot or two, no problem for us. The largest waves we have is when a big cruiser (like ours) comes out of a no wake zone and then full throttle, 2-3 foot waves

On my 3560 I replaced the original rode and chain with this:

8 Plait 5/8 200 ft anchor rode 30 ft 5/16 G4 chain

The original was 3 strand, but I decided to go 8 Plait this time. I'm sure the original was 5/8 rope and 5/16 G4 chain, but check your gypsy to be sure.

I just noticed this was an old thread, but maybe someone can use the information in the future.
