Watch
Tackle (gun tackle purchase, luff tackle
purchase), as used to get the canoes up banks and over
sand dunes. I imagine they used D or E.
Hooks aren't required, obviously!

E.F. Knight, in his book Small Boat Sailing,
gives this information:
A LUFF-TACKLE PURCHASE has the same power as the
whip-upon-whip purchase. It has one single and one
double block, the standing part of the tackle being
fastened to the single block. It is used for a
variety of purposes, among others for the main
sheet on a small cutter.
A WATCH TACKLE is a luff tackle with a tail rope
some feet in length on the double block, and a hook
on the single block. A watch tackle should always
be kept in some convenient place on a yacht's deck,
for it is employed on all sorts of odd jobs which
more beef is wanted.
It is indeed almost worth an extra hand on
board, so sailors dub it the 'Handy Billy.' Among
other things it is useful for setting up the
rigging.
It is employed as follows: the single block is
hooked on to a ring-bolt on deck, or to a strop or
bight of a rope secured to the bits or other strong
piece of timber; while the tail of the double block
is fastened by a rolling hitch to the shroud or
rope which has to be hauled taut.

by a descendant of the Mr. Wilson (sic; actually
Wulsin) mentioned in the book. Dr. Neidé's camp
would have looked something like this.
