No tricks needed
It is so easy to attach the forestay, you'll kick youself. I have had the 170 for 4 years. I used to strain, use the dumb pole, and curse. Now it takes 20 seconds. Really. Because of where the boat ramp is (under trees), I cannot raise my mast while it is on the trailer, so cannot use thr trailer wince and I launch the boat, mast down, drag it to the beach, drag it up and do everything from there.After making sure all of your mast lines are attached to where they should be and properly positioned, cleat one end of the mainsail halyard to one of the two mast cleats. Tie the other end of the main halyard (after it has passed through the blocks at the top of the mast) to another line, about 20 to 30 feet long. Give the end of that line to your helper and tell him/her to walk as far as he/she can straight away from the bow. Place the foot of the mast in its proper place on the deck, and step the mast so that it is standing vertically. Tell your helper to tighten the line as you step the mast and to really tighten the line after the mast is stepped to hold the mast up in its vertical position. Hop out of the boat, go to the bow. Get the pin out of the forstay and place the forestay near where it's going to be pinned in. Tell your helper to lean back. His/her weight is sufficient to tighten the sidestays and bend the mast to place the end of your forestay in the proper position to pin. Pin it. Done. Tell your helper to loosen the line, give her a beer.
