Another Option: Lazy Jays
I'm sure someone else has done this before, but it was an original in my marina and everybody started calling them Lazy Jays. Similar to Greg's installation but I don't like Lazy Jacks because they are there all the time. I wanted to be able to use them only AFTER the sail was hoisted, you know, for dropping the sail and holding it until I got sail ties on. I also DID NOT want to rebuild a sail cover or have Lazy Jack lines in sight when the boat was secured. So, here's how it works: (Definitely requires two people)1. Install one eyestrap on BOTTOM of boom in fore and aft manner approximately one foot forward of the sail clew.2. Install one cheek block on EACH SIDE of the mast roughly two thirds the length of the luff up from the gooseneck. (Sorry Greg, I don't care for hanging blocks on the mast, they tend to bang without pressure on them.)3. Install one cheek block on EACH SIDE of the mast roughly three inches below the gooseneck.4. Install one eystrap on the bottom the boom roughly midway between the previous eyestrap installed and the gooseneck. (Probably aft of the boom vang.5. Take a length of shock cord that is the same length as the following route: Port cheek block at gooseneck through eyestrap just aft of boom vang to cheekblock on starboard side. Run the shock cord through the eyestrap and let it hang for now. 6. Here's where the cheap nylon line from Walmart comes in handy but you will probably need a 100' length. Tie off one end to the boom (anywhere for now). Run the other end up the aft side of the mast to the port cheek block, down the port side of the mast through the goose neck cheek block and tie it off for now. Untie the first end from the boom and place a simple pulley with becket on it. (Packets of five are about $5.) Then run the line through the aft eyestrap on the boom (enter from the port side). Place another simple pulley on the starboard side. Then run the line up the to the starboard mast cheekblock, down the starboard side of the mast through the starboard gooseneck cheekblock. At this point you should have one single line run with an end exiting a cheek block on each side of the mast at the gooseneck.7. Pull the two sections from the end of the boom to the upper mast down to the sides of the boom and match them to the ends of the shock cord. 8. Take a picture, this is getting wordy.9. Make sure the two pulleys are on the FORWARD side of the nylon line and attach the shock cord to these same sections. (The pulley should be forward of the nylon line/shock cord connection.This is a temporary connection as you will be replacing the entire line with a nice "pretty" braided line when all the measuring is complete.)10. While holding the two upper sections in place at the gooseneck, take the line exiting the gooseneck cheek block and tie it with as little slack as possible to the becket on the pulley. Repeat this step for the other side.11. You're almost done! Pull the two lines running down the front side of the mast down together and your Lazy Jays will rise. (Don't pull too hard at this point as you do not want to pull out the shock cord conection completely.) Make sure the two sides are even when pulling the two lines. When even, mark the lines or temporarily sew them together.12. If you have a spinnaker pole loop you can place the sewn part of the lines under the loop to hold the pressure on the lines. If you have a track, you can install a track cleat to hold the sewn part. (Most expensive part) You can also install a small horn cleat to hold the sewn part.13. Admire your work and make any small adjustments you like.14. Cut away any extra length of line and measure it. 100' minus this length is the amount of line you need.15. Measure the length of the shock cord.16. Buy the "nice" line and shock cord color/size of preference.17. Install the new line by untying/sewing one end from a pulley and sewing the old line to the new. Pull the entire new line through the system and do your fancy work on the shock cord/braided line connection and the points where you tie/sew to the pulley beckets.18. Even up the lines and permanently sew them together on the front side of the mast at the following point: Pull the lines down to the maximum pressure required to place the Lazy Jays in the position you want for recovering the sail. Sew the lines where you would want to cleat them on the mast. OK, I think it took longer to write than to do it. The beauty of this system is that once installed, it is incredibly easy to operate. Pull down and cleat, Jays go up. Sail is tied, uncleat the line and it comes down and is covered by the sail cover. You can even rig it to operate from the cockpit by tying yet another line to the sewn part of the lines on the front side of the mast and running it to the cockpit; only one Lazy Jay line instead of two Lazy Jack lines. Entire system for 25' boat was less than $100.Pictures are forthcoming
