I just returned from a sail with a friend on his older Mac25. The traveler on his boat was a wierd arrangement that required two clam cleats on opposite sides of the cockpit. He made a new traveler out of a piece of track, new cars and clam cleats attached to a very nicely done piece of teak 1 x 4 that he attached across the vertical supports for the stern rail. This raised the traveler out of the cockpit making easier to release the sheet under strain, gave him more travel for adjustment and more room in the back of the cockpit. I wonder if this will work for my boat? His boom is longer than mine so the angle of the sheet has not changed much so he doesn't have a problem with the boom rising when the wind pipes up and keeps the sail flatter. This would make sailing my boat more comfortable and safer without the sheet clothslining someone in the cockpit during a gybe.
I take it he has no boom vang. You mentioned the boom lifting when the wind came up. You should have one on your C-25. Tention the vang to help keep the boom down and the sails flat in higher wind. With regards to the traveler I guess it would depend on what space your willing to give up and how much head room or clearance you want. If you dont race I dont see a problem experimenting to see what works.
Be very careful in making changes in basic equipment like the mainsheet traveler. I just sailed on a nice boat that was modified by a previous owner. He changed the mainsheeting arrangement and apparently eliminated a simple traveler arrangement. Now the boat barely goes to windward. Your ideas might be an improvement, but the boat's original arrangement was probably devised by a pretty knowledgeable nautical architect, and you should give any changes very careful thought before you make them permanent.
