Combinations are good
We used to have a Danforth anchor with 10' of chain and 100' of 1/2" rode. One night the wind backed and we blew ashore at 2am with a 6 month old baby on board. NOT FUN!! After our Coast Gaurd rescue, I vowed to never let that happen again. Last year I installed a double bow roller that holds a 35lb plow and a 33lb bruce side by side, ready to drop with the pull of a pin. The bruce is my main, with 95' of 5/16" windlass chain and 200ft of 1/2" twist. The plow has 45' of the same chain, and a 200ft 1/2" braid. In reserve, I keep another 200ft 1/2" twist. I have been in 30knots with 3-4ft rollers coming in the anchorage (not fun) and needless to say, never moved an inch! Might be overkill, but I sleep at night.
