A light boat is a joy and a heavy boat is a dog. And who else thinks that is a general rule of thumb???And for what kind of boats???
When I am driving our 30,000 pound GB36 and three adults and a dog or two walk up to stand on the foredeck there is no discernible difference whatsoever in the boat's trim, handling or feel. I know the additional weight up there is pushing the bow down a bit, but in terms of the boats feel, handling, or even sight picture out the front, there is no discernible change.
Do the same thing on Carey's lobsterboat and there may well be a change in the handling, feel, ride, etc. But on a heavy boat like ours, the difference between an all chain rode in the locker and a combination rode of the same length would be zero from a handling, ride, etc. point of view. Same with an anchor. We used to have a 33 pound anchor on the pulpit. Now we have a 44 pound anchor up there. I suspect we could put a 55 pound anchor up there and there would still be no discernible difference in the trim, ride, handling, or feel of the boat.
As psneeld says, it all depends on the boat.
