I've just begun renovating a 1928 (possible even 1914 - waiting for a translation) Groninger barge. It was a sailing barge until 1935 when a motor was added. The mast is still in place and I've decided to keep as it is beautiful and one day I may decide to acquire some rigging and sails. Who knows? Right now my priority is getting the hull and engine up to scratch to be honest.
My first step will be to make sure the winch operates and the mast can be lowered easily. I'll then check the wood and fittings. When I say 'I' - I actually mean they guys at a shipyard I am working with.
As I said, I'm not sure when (if ever) I'll go further with the sails but whilst I am working on the superstructure is there anything I should avoid to help me later on.
Thanks for any pointers - I realise it is a bit of a vague query.
