The old A-frame looks awful! Too low and a funny shape and its got all kinds of attachments welded on. Stainless is definatly the way to go!
One idea I am taking from the old A-frame is the horizontal hoop that goes round the back of the engines. Great for protecting them from a knock and handy for hauling yourself out the water when you go for a swim! Nice to keep the odd design feature from the original boat as well I think.
Just got home from fitting the tubes back on tonight, really starting to look like a rib now! The console looks perfect on there now, still with plenty of room to walk round and still looks like its in just the right place on the hull so I'm very happy
