    hello all
    i have a performance skiff and have been sorting out the bottom, i have come to re pack the dagger board case and have seen that i have the ability to move the board within a 30mm tolerance forward or back.

    which would be better forward or back? or should i stick it in the middle?

    Probably could use a picture of said daggerboard and the case. As far as balance goes...30 mm difference shouldn't make a difference really...depending on the chord length of the board of course.

    Agreed, the 30 mm slop could be used to benefit, depending on conditions, ail trim, boat trim, etc. As to where you want it, well, this is all dependent on what the boat wants, for the conditions it's in. Most craft of this size, rely heavily on the CB (Center of Butt) to trim them out and get her on preferred sailing lines. Having the option to slightly alter (very slightly) the CLP can be a real benefit in very light or heavy wind strengths.
