The control of the mainsheet is a multi part block always just above the traveler . One must crawl part way up the entrance to the cabinway to operate it. This arrangment also keeps me from adding a dodger style canvas to the front of the bimini. Has anyone changed this to a block down by the traveler which leads the control aft to the cockpit?? If so please send picks. Thanks. George

Can you please post a photo of the current arrangement? In the meantime, suggest routing the mainsheet to a block attached to a bail on the boom then through a block with springs attached to the base of the mast then through turning blocks on the cabin top then through a clutch then a winch on the cabin top close to the cockpit like the routing in the photo below.

No specific boat pics, but it should be easy enough to route the mainsheet aft. But first, you should run it forward to the mast, then, out and back to wherever you want the cleat to be, preferably somewhere near the helm. The reason you take it forward is to allow the traveler it's movement without disturbing the mainsheet. (isn't that the traveler's primary purpose, anyway?;))
Okay... I'll put up some pics after all. Here's one from our friend Greg's (tally ho) Oday 322:


And another post from forum member Hayden about a year ago featured this diagram:


You can run the sheet back to a cleat near the helm. Just remember that all the additional turns through the added blocks will increase the friction so you must make sure the new sheaves are large enough and of decent quality. One way to reduce friction is to go with a smaller diameter line. From 7/16 to 3/8, for instance.
Good luck, Have fun.

I thought that Mack Pack looked familiar!

Here is a shot that shows how the mainsheet runs forward to the mast, and back to a clutch and winch on the cabin top. The mainsheet (red line) is hanging to the right of the companionway.

I have decided to leave the mainsheet as is and have a single piece of canvas made that will run between the bimini s forward supports and hang from the forward bimini top s edge. This will have a fixed clear window in the top half and be able to be rolled all the way OR part way up. this will always be able to access the mainsheet blocks while allowing some weather protection. My mainsheet has a fine tuning block also and its a cool refinement.
