Hi I thought I had sent a reply but maybe it didn't go after all. The outboard
was stored on a bracket right next to the hoist so there was a little transferring to be done it's true, but it was fairly minimal and pretty all with a straight back. The arm didn't appear to be in any danger
of giving way, but it was straight, so I presume the strain just goes straight through it back down to the base.
Good luck in your deliberations . . . . . It'll need to be an awful lot warmer before I leave dry land again !
