Congrats on the new (to you) boat. The Tiger is a blast, I love sailing it.
I will tell you, there isnt much info out there about the line length. I've tried to decipher the part numbers and see if there's a size and length hidden in there, but not much makes sense. I just usually measure the boat itself , then buy a few extra few feet and trim it as needed. I also find that I buy line too big, buy the smallest size that will still work with your cleats and Vee blocks.
I love these calm moments before the storm, it reminds me of Beethoven...
