... I really
don't want to have to untie the lines at my slip every time I leave,
since
I'd have to find just the right adjustment again every time I return.

This isn't particularly good reasoning. You should have a good set of
dock lines, you should check them often. Re-tying them is not so much
trouble, think what a PITA it would be if your boat broke free.


Thanks for the advice Doug!

I guess what I was trying to say here and maybe didn't do it as clearly as I
should have is that I know that I need to adjust and inspect my lines often,
but I need additional lines so that I don't have to TAKE the lines from my
slip with me every time I go out. I'd rather leave them in place and adjust
/ inspect them as necessary, but not carry them with me. I'll buy the
necessary lines and carry them onboard, but I was just curious about the
size of line that I should buy. I have 5/8", 3 strand at the dock, but I
didn't buy that line. It came with the boat from the previous owner and
yes...it is in very good shape. I really just wondered what the consensus
was about that size of line...adequate, overkill, too small. It sounds like
it's adequate.

Thanks again for taking the time to write that long reply too Doug, and
thanks to everyone else who took the time to answer this question as well!
