It is regularly inundated at high tide; local people carry a tide table to avoid being trapped on the wrong side.

I should like a reassurance that tide tables and navigational charts are kept continuously under review.
Seafaring men, who use tide tables, are caused considerable inconvenience by these arrangements.
They control the work and equipment of the survey fleet, compile sailing directions and tide tables, light lists and notices to mariners.
There have been various references to keeping charts and tide tables up to date.
In a document giving tide tables the time used is specified, and to insert "by statutory instrument" would destroy the flexibility of the clause as drafted.
