Welcome Vic (not to be confused with Victor, who is also welcome - but just not Vic) :)

How do you know your stringers are soft?
How far up from stern to stem are they soft?
How did water get in them *to make them soft?
Is your transom soft, too?

Start by going to the "how to" forum, and learn how to do a search. Sugest you search for the words "stringer" and "seacast" and "woven". You are not the first guy, and you won't be the last guy. There have been some good discussions of this, and reading them will help you get started. There are also links on the home page to other worthwhile sites like "thehulltruth" and the Seacraft websites that will also yield good info with such searches.

Good luck, and a picture is worth a thousand words.
