Something to be concerned about?

Crack.jpg

Been keeping an eye on this crack since the spring as I cannot tell if it is a gelcoat crack or actual structure crack. It's about a foot long and is right on that strake. It hasn't gotten any bigger since I noticed it. The gelcoat is 37 years old. Boat is an 1981 Glasstream 1500V

If it’s staying the same size and not running it’s prolly ok. Tap it with the handle of a screw driver and see if sounds good and solid.
