was it refered to -- in history -- as a "U-Boat"? if so, did it reduce sail
powered to commercial vessels to nothingness? If not, when was sail powered
commercial shipping kaput relative to U-Boats?



sail powered commercial shipping was kaput long before any u-boats got on
this
side of the atlantic.

For your information, approximated 25% of ALL
commercial shipping vessels made in the last 50 years of sail powered
shipping
sunk before the boats were retired. one in four.

it was those darn U-boats hiding in LIS.
