I have a full battened loose footed main sail with two slab reefs.
The reefing lines are internal in the boom and exit the boom at the stern end, one on each side of the outhaul.
I will have a boom bag and lazy jacks made that will be attached to the boom with slides in the boom track.

Most or many slab reefing lines one sees have the reefeing lines going through the reefing cringle and back down to the boom and tied to the boom with I think usually a rolling hitch.

My Question:- Is it necessary to take the lines back down to the boom or can I simply tie the lines to the reefing cringles with a bowline or halyard knot?
