Any good anagrams for frapping a ship?

The act of passing four or five turns of a large cable-laid rope round a ship's hull when it is apprehended that she is not strong enough to resist the violence of the sea. This expedient is only made use of for very old ships, which their owners venture to send to sea as long as possible, insuring them deeply. Such are termed, not unaptly, floating coffins, as were also the old, 10-gun brigs, or any vessel deemed doubtful as to sea-worthiness. St. Paul's ship was "undergirded" or frapped.
