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
