Hi All,
I finally got my 1985 Laguna 30 on the mooring. I could use some help rigging the center mainsheet setup - here's the little I know:
I have 2 double blocks mounted on the deck - 1 to port and one to starboard - about 6" to the side and front of the companionway. There is also a double block in the center of the boom. The line was removed ( probably one of several in the locker ), but I don't know which one or how it would be rigged thru these blocks. I think this is the setup used instead of a traveler arrangement. ( the boats in my ASA lessons were all new and had travelers. ). I'll be back on the boat tomorrow so I can shoot some pics if needed.
Thanks in advance for your help!

The pictures will help. One of your blocks likely is a fiddler block. The mainsheet will attach to the fiddler block if there is one. Or there will be a hard point to attach the line to near one of the blocks.
Here is an image of one setup.

It talks about a transom when the boom block is at the end of the boom. But this can also be a mid boat rig.

Excellent! That's going to be a big help. There's not much info out there about these Laguna 30s. I've looked all over the web, but didn't see anything with this type setup. I'll definitely take some pics tomorrow.

Take pics of all your attachment points for all rigging. Also pics of all electrical equipment. Keep 'em for future reference.

A majority of the pics I see online show a traveler in front of the companionway. The rest go to a block in the center of the floor in the cockpit.

I'll take a bunch of pics today - hopefully the rain will hold off a bit. Heading there now.

If you do this where the traveler usually goes just short of companionway, instead of on the transom, you will block all access going forward or into cabin with all those line angles.

Not necessarily John. The rigging is set to the cabin deck on each side of the boat. This type of rig uses blocks set on mast side of the companion way. In the same general area as mid deck traveler system except you have two sets of blocks instead of a single block attached to a sliding car on a traveler track.
I prefer the end of boom design system but boats are designed by different folks with their own ideas. That is one of the beauty's of this whole sailing thing.

There is no traveler in your photo and he stated his blocks are just 6 inches to side and back of companionway on starboard and port sides. This will make getting into cabin very difficult under sail as one or the other line will be in front of door on a tack. The other line will block going to the downwind side of boat. That setup is meant for the transom only.

Without pictures I think we're missing something. He also said double blocks on each side and on the boom. It seems to me he needs at least one more sheave on the boom.

Hi All,
First off - Thank You for replying to my post - I sure appreciate all the help.
I got on the boat last evening and took a bunch of pictures. I'll attach them here.
I did make a mistake describing the block on my boom. There are two double blocks there.
Sorry about that - thats why pics are so helpful. You can also see the two double blocks at the front of the companionway as well as the bottom of the boom.

Could you treat each side as a separate mainsheet? (Just thinking with my fingers here. I never saw or used such an arrangement.)

Run a separate line through the blocks on each side. Use whichever side seems most useful depending on the side from which the wind is coming. Might get complicated, but by hauling in on the windward mainsheet you could surely pull the boom to windward. The attachment point on each block just outboard of the hatch trim would provide the beginning point for each mainsheet.

Are there winches or jam cleats/cam cleats nearby and aft of those blocks?

Putting up the dodger or bimini bow that is in the picture might help you visualize where the lines can not be.

Appears to be a home made set up to work around the bimini. Missing any kind of fiddle block for termination point. I would move to end of boom and install a traveler. That boom bale was originally placed there for the missing boom vang, note the attachment hardware for it at the base of the mast

Have to agree. Just looked at many pics of Laguna 30's,, and ALL had end boom sheeting. Although the spec sheet drawings show a traveler across he companionway,, and mid boom sheeting

Hi All,
I did finally run each side as a separate mainsheet. I found a couple mid boom layouts for smaller boats to give me a clue, and basically added an extra loop thru the second roller. I've sailed the setup two weekends now and it works like a charm. Its really not much more effort, and I'm happy about the leeward sheet acting as a accidental jibe preventer. I can see where the previous owner removed the traveler from the ledge at the companionway, so I'm pretty sure you are correct that the mod was made to facilitate the dodger.
Here's a pic -

If it is working that's great. Sail it. There are many other things that will develop into "oh my gosh how do I deal with this"..
have fun.
