many questions about repairing/replacing stringers

[tartuffe]

One thing I forgot to add in my post and that is in regard to the structural integrity of what you are doing.

The fiberglass hull without stringers or cross members/bulkheads is very flexible. When you go over a wake or wave and smack one square on the backside and your teeth rattle your boat absorbed alot of force. The areas furthest from the internal structure flex the most while those at the substructure do not flex at all. While not always teeth rattling, this force and flex happens constantly.

Your goal is to gradually transition that flex to the inflexible point over as large a distance as possible. Multiple layers of tabbing starting 6" from the stringer, then 4", then 2", to your filet disperse the flex and prevent what are referred to as hard spots. Its very important.
