    Default SK Boat Crane Hardpoint Certification?

    Now, I'll admit it's going to be a bit before we are ready for our SK race boat to be craned into the water at one of the Clayton Race Boat Regattas. However, we were looking over the boat and it got me thinking I should at least ask so we know for the future. I read in the literature at some point mentioning boats that are to be craned need to be certified.

    The boat is an approximately 1960-1962 Raysoncraft SK boat and has the hard points for craning. Who would I contact, how long is the process, how is it done, and how much does it cost? Any help is appreciated.

    Thanks,
    Brandon

    Default APBA minimum standards

    http://www.apba-racing.com/sites/all...2INBOARD_0.pdf

    Rule 3.9 SLINGS: All slings shall be manufactured to industry standards. The slings must be identified by a serial numbered patch or identification tag. The
    slings must have an original manufacture rating displayed on the patch or identification tag. The minimum sling standards for each class are as follows:
    4 leg sling = the minimum weight of the boat per leg
    3 leg sling = 1.5 times the minimum weight of the boat per leg
    2 leg sling = 2 times the minimum weight of the boat per leg
    1 leg sling = 2.5 times the minimum weight of the boat
    EXAMPLE: A 5 Litre, 3 leg sling would have overall minimum rating of 5400#.
    (1200# x 1.5 = 1800# per leg x 3 legs = 5400# minimum)
    A single point lift 2.5 Litre Stock minimum would be 2125#.
    A four point lift 2.5 Litre Stock minimum would be 3400#.
    The included angle of the slings shall be 45 degrees or less.
    3.9.1 All slings must be pull tested every three years. A letter of verification of pull test with the sling serial number or identification number will be
    required. The amount of pull per leg will be 2 times the manufactured minimum per leg.
    EXAMPLE: A 5 Litre 3 leg sling would pull 3600# per leg.
    (1200# x 1.5 = 1800# x 2 = 3600#)
    A single point lift 2.5 Litre Stock would pull 4250#.
    A four point lift 2.5 Litre Stock would pull 1700# per leg.
    This does not preclude an inspector’s right to deem a sling unsafe.
    All lifting hardware on the boat must be of sufficient strength, and attached properly as to support the entire weight of the boat from any one of the
    lifting points. All lifting hardware must be visible for safety inspection.

    Interesting. I was unaware it was the slings that we're certified, I just assumed that the crane just used the same slings for all the boats at the race.

    I guess when the time comes I have to purchase some slings.

    Thanks for all the info, very informative.
