That displays remarkable faith in the local tides. Faith that appears
to be unfounded at least judging by local incidents in E Scotland.

Other than that, knowing how to do a deep
water re-entry is enough for most people.

Same thing applies practice. Deep water re-entry is one thing,
doing it it 2m swell with a gale going on is going to be another.
