The Monarch website says:
"The bow and stern lines are tied to a piling, cleats, or the bulkhead (if
there is no dock) and the two spring lines criss-cross. These lines are
for
control of fore and aft movement."
I haven't any idea what they are saying. What lines are necessary, and
where do they go. It is for a 15' sailboat.
