Might have to screw in a little hardware into your boom in several places to tie on and either on mast or under your spreaders but were talking a couple hours here nothing more...some folks like them to retract out of the way some dont care...so it dosent have to be internally lead in the mast or get real fancy to have efective LJ ..here is about the simplest way to do it ...there are tons of examples out there...both retractable and stationary. These would be considered stationary even though they are adjustibal.
Lazy Jacks ( sailnet store keeps steeling my link...Give me a minute )
There are kits for around 2 to 300.00 but you can do it yourself for 50.00
I have a 40 footer so there are 5 attachment points on my boom so you might need 3 or 4 on yours but thats just a couple extra rings or direct ties down from the main line to the boom at angles.. mine was/is 1/4 cotton line...if it has to break it will..
