Find someone who has done this before - if the boat is in the water and has been used but you suspect it wasn't done right, borrow a person with a Loos Gauge, which is used to check the tension on the wires. There are instructions on the gauge. My boat is bigger than yours, so my tensions are likely to be higher and my wire sizes are larger, but I use 1100 pounds for the upper shrouds (wires going to the top of the mast), 700 for the lower ones and 1500 for the back stay. I hope someone has the proper numbers for your boat - I would guess they are no more than 3/4 of what mine are. The gauge has a table on the back which has readings for each wire size.
If the boat has just been launched for you, then you have to start from the beginning - and I would do a search on 'setting shroud tensions on a sailboat' to get the basics (things like how to assure the mast is vertical - side to side - and how much it should be leaning back from the vertical - in the boat) and hope you can find the appropriate measurements for your boat. If all of this is Greek to you, I would suggest finding a person with rigging experience to get you on the right track. It isn't rocket science, but is important for your safety. If the boat was set up by a boat yard before launching, then maybe the club members are just dazzling you with their 'superior sailing' knowledge.....and you can defer this discussion for a while.

I have only had one sailing lesson , so I do not know much about sailing or rigging . The people at the sail club I joined said the lines have a certain tension and since my boat is a 1975 I do not have any info for how much tension. I would like to set it by a gauge for now.
