end of the boom , and secure it using a knot-on-knot .
Please note, the mainsheet block will be supplied in the forward position: if you plan
to sail with a crew you may wish to move the block to the aft position to give the crew
more room, to do this, simply unshackle it from the forward loop and move it to the
aft loop.
It may be easier to compress the spring using a pair of small cable ties until the
shackle is done up, then cut the ties to release it.
