Giulietta-

The problems I see with the mainsheet running directly from the forward boom bail block to the foot block are:

1) the load on the mastbase block increases dramatically;
2) the mainsheet is now an obstacle that will sweep the area under the boom;
3) the mainsheet may cause problems with the hatch that is present,

T34C-

If the boat requires the use of a mainsheet winch, you can probably increase the purchase of the mainsheet by changing the blocks on the boom and traveler, and possibly even eliminate the need for a mainsheet winch.

However, if the increased leverage won't be sufficient, then you will have to run the mainsheet forward to the mastbase block, probably by moving the existing to just aft of the boom vang attachment, so that the main sheet parallels the boom vang but leads fair to the mastbase block.

This should avoid most of the problems associated with just running it from the existing mid-boom sheave to the mastbase block, but the loading on the mast base block will be significantly higher.

My reasoning that the tubing you see is for a bimini is that it is angled down and aft in the photo...which means it is attached somewhere in the cockpit, which is very unlikely for a dodger, and very typical for a bimini. The bimini frame on my boat, when lowered forward, ends up in almost the exact same position relative to the sliding hatch and companionway.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
