We had a Westsail 32 which is the plastic equivalent of your boat. Your boat is an Eric if it has a trunk cabin
or Thistle with a flush deck
You do have a roller reefing boom. I'd forget about ever using it as they result in a really crappy setting sail and are much more labor intensive to use. Almost everybody has converted their roller reefing boom to slab reefing because it's so much faster, easier, and results in a well set sail.
As many people have said, go with slab reefing. Put a cheek block on one side of the boom and a padeye on the other so that the when the sail clew is pulled down to the boom, the reefing line makes at least a 45 degree angle with the boom. Schaeffer makes a cheek block with a curved base that should be ideal for your boat. The 5 series block should be adequate. Doing it with a the block on one side and a padeye on the other will work with a bolt rope
set up like yours. Tieing off the other side of the reefing line back to the cheek block willl aslo work as described above. You will probably need to put a winch
on the boom. We couldn't get enough tension on the clew reefing line without a winch
. Put blocks and padeyes for each reef point and at least two cleats
at the fore part of the boom to secure the reefing line. You will also need a way to hold the tack of the sail at the mast
. A line running from one side of the mast
through the tack reefing cringle and back to a cleat will do just fine. Just rereave the tack reefing line as you pull each reef down. You may be able to get by without a winch if you use the topping lift
to take all strain off the sail via the lift
when you're pulling in the clew reef.
If you want to take the time and expense, running the reefing lines and main halyard
back to the cabin
top, it will make reefing way easier. I've done that with separate lines for the clew and tack with my current
boat. It's really nice to reef without having to leave the cockpit
. Harken has illustrations on what you'll need to do that. Using line clutches, you can get by with one winch for both the halyard
and the clew reefing lines.
