I have the same problem with the all-alu H16 mast on my Tremolino tri. It has a dent that is not as deep as yours but the mast is like a bow. The dent is in the lower third of the mast, the side. I have sailed the boat for two months now and it is not great but works. Did not really press the mast with the downhaul. I agree that bending aluminum back just might crack it. How about riveting a sleeve on top of the area?

<br>The unfortunate thing is that I bought a mast from FL which arrived with a dent above the forestay attachment, so now I have two bent masts. The second one will work great with comptip replacement though - any takers in Boston area?
