middle of the Broad Part thus instead of the side, as in
common Rudders thus . This was for a reason which
Seamen will readily apprehend, and which I apprehended
at the time but have since forgotten.
The great principle upon which the advantage, expected
from this Construction in point of Swiftness depends, is,
that according to a Maxim received, my Brother says,
by all Ship Builders theoretical as well as practical,
a Vessel meets with no sensible retardment from its
length. But by increasing the length you may —
increase indefinitely the number of Rowers, and
consequently the moving force; while the increase
of Length as far as the above Maxim holds good,
makes no sensible addition to the resistance,
What sets Limits to the Length in all Plans of Construction
hitherto known
is the Vessels capacity of holding together without falling to pieces by its own
weight, which is called Hogging by Seamen. My Brother does not know that
anybody before him ever put two rows of rowers close together on the same
side they row without interfering with one another in the least. —
Of the particulars contained in the above description scarce any were
furnished me by my Brother, his attention was sufficiently taken up partly
by an Ague partly by the Conducting of these unexampled and untried —
Vessels with a Crew perfectly raw and unexperienced through a Navigation
rendered as dangerous by sunken or projecting Stumps as a Sea Navigation
by Sunken Rocks. —
When I embarked, he had had his Ague for about ten days and he was
so weakened by it as to be unable to stand and sometime
