Another method of reducing dead-air space is adopted by the more macho
members of our underwater hockey league: they saw off their snorkels, so
that the end is at head-top level or below.  The reason for this
modification is actually to reduce drag; a few leather-lungs types do
without a snorkel entirely.  Ya gotta be tough.

Unfortunately, this has limited applicability to open-water diving.
Manufacturers design snorkels to keep the majority of wave-tops out of
the end, and expect their users to object to breathing water.
