This arrangement introduces a lot of unnecessary friction to the system and will cause the line to fail at the slot in the boom due to chafe in any extended blow. Eliminating the bull's eye block below the boom will eliminate these problems and create a fairer lead to what I assume is a turning block at the mast base. Single line reefing sustems are great in theory, in practice, not so much.

Removing the bull's eye will create a new problem...
The reefing line will pull the sail away from the mast casing wrong load pattern on the sail.
So if you remove the bull's eye you must move the reef cringle furter aft in the sail.
