slightly bent mast.
 
I bought an old Y-flyer yesterday basically for the trailer under it. It is in pretty bad shape. In fact, there is a fiberglass copy of the hull profile sitting on top of the old hull where someone had started to build a modern version of the boat by hand. The mast appears to have been strapped down across the bottom of that hull and pulled down hard enough to shape it over the hull.
Is it acceptable to place a mast that has a small bend in the middle across a curved surface and slowly pulll it back straight with straps? Should it be done a little at a time over a period of days, or all at once. The bend is not severe.
Thanks in advance!

The Y Flyer has a rather "bendy" mast so it will be hard to get it to bend back in exactly the right place. You'll also risk breaking the mast. If the bend is at or near a cutout, screw/rivet hole or other point where the structure has been compromised, there is a higher risk of breaking. I'd say leave it alone.

I think that I would probably just turn the mast over and strap it down to the hull again. Rig up a way that you can pull it down a little at a time until you can take out the bend but don't worry about doing it quickly. Waiting days isn't going to help. If the curve of the hull isn't sufficient to get rid of the bend then you may need to set something else up.

Go for it. Try to bend it back. I doubt you'll get it totally straight, but it's no big deal if it's not.

I used to straighten bent aluminum light poles all the time, after they were knocked down by cars! The small ones I'd place on a couple of wood blocks located as evenly from the center of the bend as possible and I'd bounce up and down on it until it was straight. Sometimes it took two or three of us. On the bigger poles I'd just lower an out rigger from our crane or bucket truck on it. You'll be amazed at how far you'l have to overbend it to actually make it straight! Go for it!!

I'n not familiar with the rig of a Y-flyer but if it has spreaders and a backstay I'd be tempted to just raise it and tune it plumb with the standing rigging. You'll probably have to keep at it frequently but eventually it ought to work back to shape.

I can just see trying to bend it and suddenly finding out that last tug or push was too much. From what I've seen when they go they do it all to once. (Had a wood one let loose on me and it sounded like a .30-06 blast!).
