Bent top masts in the Laser® are not fast - you loose leach tension which in turn effects your pointing ability. This video shows you how to check for a bent top mast, how to straighten it and then if you are convinced it is close to breaking, how to end for end it so you now have a new top mast.
You will see from this video that I was pretty convinced that this top mast was ready for end for ending. The bend on it was quite extreme, which meant that I was going to have to stress the rivet hole to get the mast straight; they say aluminium only bends and straightens nine times before breaking and as this was also a second hand mast you never know when its going to fall over.
Please forgive my lack of pillar drill, vice, etc. This is what I call boat park engineering. I hope you find the video informative.
