>>859715I was a boy scout for 12 years and I sail. Also a member of the fire service. There are what I have committed to memory.
Bowline
Half hitch
Clove hitch
Two half hitches
Taught line hitch
Timber hitch
Square knot
Sheet/Beckett bend
Water knot
Figure 8
Figure 8 on a bight
Figure 8 follow through
Handcuff knot
Square lashing
Triple lashing
Straight lashing
Sheep shank (party trick, but a knot)
Couple of fishing knots for joining mono line and attaching hooks.
FYI- figure 8s are less stress on your rope than bowlines and can accomplish all the same tasks
