Just bought a Y30. It seems that there was an inner forestay that is now gone. I've since seen another Y30 with the inner forestay and it has a block and rope tension adjuster integrated on it. I was just wondering if this inner forestay is absolutely necessary or if it is some kind of racing luxury? If I get into heavy wind will the forestay break without it?

Your inner forestay, (baby stay) prevents the mast from pumping in heavy wind conditions. It will also help to bend the center of the mast forward which will reduce draft in the main. I would make sure it's in place if you intend to sail in heavy air as severe mast pumping can cause catastrophic mast failure.

My 1984 Yamaha 30 has a fixed baby stay (the only means of adjustment is a turnbuckle). As much as I would like it out of the way to enable me to carry a dinghy on deck, I have never removed or disconnected it. It would be missing just when you need it most.

Ted is correct, although if it's not that windy, you really don't need it! I have a Y33 and disconnected the wire babystay and replaced with dyneema which is strapped to the shrouds out of the way and easily clipped back in place when needed. You'll only need it when the main is reefed down...to bend the mast you'll need quite a bit of purchase on it (4 or 6:1 tackle) but I just nip mine up with a 2:1 to provide a bit more stability for the rig.

Having the babystay out of the way enables one to easily jibe the spinnaker (or hoist the hammock).Since taking the stay off I think I have put it back on twice when sailing in the relatively light winds here (10 -20kts) but I usually leave it on at the mooring during typhoon season.
