I used 5/16ths for all my lines 1/2 sounds a bit too big for the blocks on my boat anyways. I believe 5/16ths poly braided line gives you about 4,200lbs I think it to be sufficient, also I heard that sometimes it does not make sense to use the "bigger the better" in terms of line, if you are not stressing the load of the line then it may weaken in time, and be less effective.
The mast itself for a B23/25 circa 1975 is 29 feet to the deck. Jibs are usually measured one and a half times the boat, I think 54' is too much in my opinion. Depends what you are flying, I have a 150% Genoa, which already goes past the mast, so you really only need about 20' of sheet on either side.
I put two forward hallyards just incase, and replaced my main hallyard, again 5/16ths, and 65-70' for both will allow you to have the lines running back to the cockpit with some to spare.
Wiring in general in my B23/25 anyways, from the fuse box runs along the port side beside the joining of the deck and hull until you reach the chain plates, then it dissappears inside the cabin lining, goes to the port and starboard lights, to the mast, and one to a light for the v-berth.
Off the fuse box you will see some switch connections with black wire, and a whole bunch of negatives "white" wires soldered, bent, and wrapped with electrical tape. Atleast this is how mine came from the factory. Get yourself a negative bus bar, from blue marine, with cover, and a bunch of terminal connectors, and break up that bunch of negative connections and put them properly on the bar. Then screw the bar, and cover on to the board from the inside, beside the fuse panel. A 20 minute job, but cleans it up nicely. You have a group of grounds connecting to the block, including a ground for your gas tank that is taped on the scuppor drain over the engine and then grounded, you have a wire running to the transom for your steaming light, and from the fuse box to the engine room, then across to the starboard side of the cockpit, you have your engine switch, and your blower, that is if your bayfield is a 23/25, with gas engine.
Check your chainplates, esp. your bulkheads to see if they have been leaking. Check your rigging, to make sure their are no freyed wire anywhere, if it is, replace them. Replace your mainsheets, at the end of the boom/traveller. Get a kit and learn how to splice loops in your braided lines. Once you get good at it you will be glad you learned. Marine Shops in Toronto charge about $20 per splice, and if you are replacing 5-6 lines the price adds up.

Subject: [BYOR] Mast Height
Hi, We recently purchased a Bayfield 25 in some what poor shape. We
have been cleaning it up and it is starting to look good. We need some
information such as the mast height from waterline and also we are
going to put new lines on. I have measured the Jib Sheet as 54' and 1/2
in diameter, Jib Halliard 65' 1/2 in diameter, Main Halliard 67' 1/2
diameter and leech line 62' 5/16 diameter. Do these measurments sound
right and are there anyother lines we should change. If there is
anywhere that has any wiring or layout drawings please let me know.
