Joel,
I’m not sure aluminum would be up to the task. I think stainless might be a better choice. Same sizing, but much stronger, but even stainless will bend under the right load. Perhaps a spar maker might be of assistance here. They bolt on cranes all the time. A premade one might be your best option.

I would like to add a crane to move the spinnaker halyard block forward of the headstay about a foot. Selden does not make a pre-fab crane for large boats. I was looking at a 5 inch aluminum channel: <http://www.speedymetals.com/p-2221-1885-x-0325-x-5-325-channel-6061-t6-aluminum-extruded.aspx> http://www.speedymetals.com/p-2221-1885-x-0325-x-5-325-channel-6061-t6-aluminum-extruded.aspx Any idea if this could handle the load? Should I go for stainless? Thanks. Joel
