Very excited to have acquired a new to me H16! Im keen to start sailing as a novice and have a few questions Im hoping you all can help answer! pictures included!
First:
Is the amount of corrosion on the boom acceptable? is there an easy fix, or just sail it?



Second:
On the mast, the cheek block (which I assume is for the jib halyard) is shot... The pulley has completely deteriorated as you can see. Any recommended fix besides riveting a new block? Is it true you can use the pin above the pulley instead?

Last but not least:
I have a bunch of wire Im not sure where or what is goes to. I will number the pics for ease of identifying.
