A memoir of life as an adventurer and sailor in the Mediterranean,
by the noted naval historian. Ernle Bradford spent his twenty-first
birthday in Egypt, serving in the Royal Navy during World War II.
It was there that he came across the profoundly affecting words of
Anton Chekhov: "Life does not come again; if you have not lived
during the days that were given to you, once only, then write it
down as lost." After the war, Bradford married and settled in
London, but the mandate of those words inspired him and his wife to
quit their jobs, sell their home, and sail to France in their small
ship Mother Goose. The Journeying Moon chronicles their adventures
as they travel through Europe and the Mediterranean. From the
people of Malta who believed Bradford was a spy from MI5, to his
interactions with the Sicilian Mafia, Bradford tells the charming
and vivid tale of his days as a true adventurer.
High speed catamaran and multihull high speed marine vessel have
become very popular in the last two decades. The catamaran has
become the vessel of choice for the majority of high speed ferry
operators worldwide. There have been significant advances in
structural materials, and structural design has been combined with
higher power density and fuel efficient engines to deliver ferries
of increasing size. The multihull has proven itself to be a
suitable configuration for active power projection across oceans as
well as for coastal patrol and protection, operating at high speedd
for insertion or retrieval with a low energy capability. At present
there is no easily accessible material covering the combination of
hydrodynamics, aerodynamics, and design issues including
structures, powering and propulsion for these vehicles. Coverage in
High Speed Catamarans and Multihulls includes an introduction to
the history, evolution, and development of catamarans, followed by
a theoretical calculation of wave resistance in shallow and deep
water, as well as the drag components of the multihull. A
discussion of vessel concept design describing design
characteristics, empirical regression for determination of
principal dimensions in preliminary design, general arrangement,
and methods is also included. The book concludes with a discussion
of experimental future vehicles currently in development including
the small waterplane twin hull vessels, wave piercing catamarans,
planing catamarans, tunnel planing catamarans and other multihull
vessels.
