Yup--Corrosion at horizontal joint of dissimilar metals covered with crappy looking old powder coat on non-anodized mast! No surprise to me.
In 30 years I've NEVER seen a anodized (Hobie or Nacra) mast break like this. Their holes wallow out where stainless steel pop-rivets are wet with salt water, tho.
Also many extrusions are thicker on the side walls.
