Re: Anchoring with changing tides and wind
1 - Observe what others have done and do similar
2 - Anchor in areas of similar size boats with similar rode if you can (a boat on all chain will swing quite differently than one on chain/rope)
3 - Be aware of the expected tidal change - both for depth under the boat at low tide, and for adequate scope at high.
4 - As has been said ensure anchor is solidly set - this goes for swinging free, of course, but ESPECIALLY for stern tie situations. Cross winds/current can put very heavy strains on the anchor and rode.
Seconding Jackdale.. never seen a Bahamian anchoring setup here, and one boat anchoring bow and stern can ruin a bay for others that would prefer to swing free.
We stern tie a lot, but actually sleep better swinging free. On a windy night the only way I can relax if stern tied is if the wind is coming off the beach. Otherwise it's either a crosswind, or you're on a very close lee shore. Remember if the anchor lets go then the only thing you're tied to is the beach.. or rocks... and that's where you'll go... Still, it's a common practice for many reasons, and in reality in summer (in our area) for the most part the winds shut off overnight if the weather is fair and settled...
