Hi.
I've decided to go with a simple A frame formed from 2 galvanised steel
tubes (1 3/4 inch inner diameter), 6 metres in length (about 20 feet).
I've drilled 10 mm (1 cm/0.4 inches) holes near the tops of the poles to
take a bolt which allows the frame to pivot at the top.
I'll guy the frame fore and aft.
I'll secure the feet of the A frame to the forward U-bolts on side deck.
(I should "chamfer" the feet so they rest flat on the sidedecks.)
My only (for now) remaining issue is how to protect the side-decks from
the feet of the two legs.
One suggestion - just secure wooden pads to the deck before resting the
legs on wooden pads and securing?
Alternatively: source heavy rubber "shoes" to fit over feet of the two legs.
Or tapered wooden pegs hammered into base of each leg??
Any suggestions welcome.
