    I have sailed a few times (long time ago) with a similar sized boat with really heavy center board. It had a hole through the board, and some kind of bolt to put through, so when you lifted it, you pushed the bolt through to prevent it from falling back down. It was a very stable boat to sail... That said, it is really long time since I sailed that boat.

    Okay, I found on the Internet the same kind of boat I sailed a bit with. It was a Fabola Pokus. Some claim the center board is 60 kg, other say it is 70 kg (about 130-155 lbs). All I know is that it was really heavy even for an adult.

    The boat is a little bit shorter than a GIS and many claims the heavy center board made to boat boringly safe.

    Heavy center board are best handled if you put them in place on land and then with a trailer put the boat in water. This is of course a luxury not possible everywhere.

    Hi, thanks for the info on that boat with the heavy centerboard. It looks like a daggerboard (it slides up and down rather than pivoting back?) It's something I've thought about, but I'm not sure it would work for me, I'm often launching where I have to use the beach trolley, and I'm not sure I'm ready to put all that work in with steel plate or casting lead.

    I doubt I'll go with ballast as a matter of course, but having some bags I can fill with sand/gravel on the beach and stick either side of the daggerboard case could provide a useful option if I've got a tricky passage to make to get home.

    Thanks,

    Ian

I get the impression that people who have tried a heavy daggerboard have quickly gone back to their conventional one. It would be good if someone can point to some first hand accounts of trying a heavy daggerboard on a boat of similar size, I'm not sure I'm prepared to go to all the trouble of making a heavy daggerboard without having heard of a positive experience from someone, it must have been tried.

    Sandbags at least will be quick and easy to make and try, and throw overboard if I find they're not helpful.

    Good points. David Graybeal, who really started off sailing in his Goat used sandbags - and they worked for him for the first year. Then he got rid of them. BobWes still uses them singlehanded.

    Swinging boards won't work in the Goat - The case is too far back, the floor is too narrow - it is going to be a big impediment to moving around the boat or finding a comfortable place to sit or kneel or move across the boat to balance.

    The few times I have sailed with heavy centreboards it has been a pain. Instability as you come into shore and raise them, or trying to get over a shallow patch becomes difficult. Devoting one crewman to getting the board up coming into a beach or lifting to go over a sandbar.

    Plenty of stories of boats going over anyhow and the board falling out of the case - it is a lot of weight to control.

    I do think the sandbags make a lot more sense.

    Finally a picture of the yawl on the water:

    A nice gentle breeze day, I could get out under full sail with the kids on board. The balance with the centreboard in the "yawl position" was just right - only needed fingertips on the tiller, but turned gently into the wind if I let go the tiller.
