Having an issue getting the arch and permanently attached mast off our boat to get up the Illinois River. Planned to stop in Seneca and try to use a crane to pluck it off. Problem is the sink/refrigerator housing is attached to part of the arch. I’m sure 5200 was used as it was recently removed and reattached for some soft floor repair. I’m sure there will be damage once the arch pulls free. The other option was to cut the arch for removal then have a hinge installed to reattach the arch. Figured this would be the most pleasant/less expensive way but Seneca does not have the ability to cut the aluminum. Any possible local suggestions? I’ve looked for local shops but wanted to check the brain trust here before I do dial a cutter. Thank you in advance.
