After answering the question of how much rode you have.. the next qualifier is windlass or not? We still use the Armstrong retrieval method and so try not to anchor deeper than 50 feet or so with chain/rope rode. That can be a challenge in BC as we are not known for shoal waters, but most good anchorages do provide areas of 20-40 feet.
Of course with all chain rode lifting by hand is much more severely limited. Then you want that typical 15-20 feet so that that's all the chain you actually need to lift at any one time. We too anchor in 5-6 meters max in the Caribbean with all chain and no windlass on our friends' boat and hoisting that back aboard can be a challenge when the wind pipes up.
