When building either a complete boat or a rig remember the adage – “keep it simple” this serves 3 purposes
1) less to go wrong
2) its normally lighter!
3) It can cut costs significantly

Take a look around there are plenty of examples that demonstrate a bit of wire or a piece of string can do most anything!
