It reduces but doesn't eliminate the need for a boom vang. Having the traveller up there makes it effective over more of the boom distance.
The traveller is used to give you independent adjustment of boom position and leech tension. When you are close hauled you use the main sheet to adjust the leech tension (normally done with the vang) and the traveller to adjust the angle of attack of the boom.
The simplest instruction is to use the main sheet to adjust the leech tension until the top batten is parallel to the boom. Use the traveller to adjust the boom position until you have a neutral helm. If there is weatherhelm then ease the traveller, if the main is luffing then just bring the traveller in until it stops.
With that traveller position you'll probably find that you can use it for close reach and close hauled. When you get to a beam reach the traveller will be fully eased and you'll need to ease the main sheet to get proper boom position.
This is a great upgrade compared to the stock system on the C-25.
...unless by "cabin hatch" he means the companionway, mounted across the seats at the bulkhead. That's what I'd have done (and considered doing). No more decapitations!
That's right. It's located level with the cockpit seat right in front of the companionway. A little inconvenient going into the cabin under sail, but moves out of the way pretty easy.
My 25 has mid boom sheeting. The fiddle blocks are on the bulkheads each side of the companionway. When I bought the boat it was a continuous sheet through all the blocks. I was unable to get the boom to the middle of the boat. I fixed the sheet in the middle block on the boom and now I can get the boom to the center-actually past center. The disadvantage now is that I have to remember which side of the sheet to pull/release where with the non fixed continuous sheet I could pull either side to move the boom, at least until all the line ended up on one side. So far I prefer the fixed sheet as it allows me to point a little better.
