Building Lazy Jacks

[Mariner4152]

Greetings everyone,

I am thinking about building a set of Lazy Jacks for my boat. I am getting into doing all my own rope-work. I have a small 19 ft Stuart Mariner. It is essentially a day sailor, my first boat and lives on it's trailer most of the time. I sail primarily with my wife and two young children. Most of our trips involve stops at beaches for the girls to play. The Main is fitted with sail lugs so it stays in the slot but it is still all over the place until I get it loosely furled onto the boom.

While at the Great Lakes Tall-Ship Challenge in Chicago a couple weeks ago, I noticed two different types of lazy jacks. Some with blocks on the legs and others with ropes spliced into the lazy jack halyard. From the information I have been able to find on the internet, the preferred method of construction appears to involve using thimbles or blocks for adjust-ability.

I am planning on building the jacks using 3 strand 1/4 rope. Install a couple cheek blocks about 70% up the mast and a couple of small cleats near the bottom of the mast. I was thinking I could just splice the legs into halyards. Install 3 eye straps along the bottom of the boom. Splice a small fast-eye clip at the bottom of each leg. That way the whole system would be easily installed/removed when getting the boat read to sail/trail. The mast is about 25ft tall and the boom just over 10ft long.

Any thoughts on why this would not be a good solution?

Do you see any problems?

Thanks in advance for any suggestions or opinions.
Greg.
