Blocking Guidelines

     Agonic Marine Transport recommends the following guidelines for the blocking required to block boats, power and sail. 

Power Boats

     The blocking used to block power boats is usually called "cribbing".  Steel jack stands are the best for blocking power boats for maintenance and storage but are generally expensive and hard to get.  Cribbing is made by using 16" lengths of 2X4's alternating each direction.  For easy of handling we recommend making the cribbing with these dimensions.

  16" X 16"X 16" 

(This is two (2) of the cubes stacked)

       Stacking two (2) of these cubes gives you the height for the back corners of the boat and single ones for the keel.  For larger boats, a block is required under the engines and another stack of two (2) amidships along both the sides. 

    To make a set of cribbing for an average 30ft boat you will need approx 40, 8ft 2X4's made according to the instructions above.

 

Sailboats

     Sailboats are blocked by making a custom wooden cradle or by using steel jack stands provided at most marinas and boat yards.  Custom cradles vary depending on the size of vessel and the keel configuration.  We use 2x6 and 4x4 lumber for the upright supports with the majority of the weight being supported on the keel. 

  A firm, solid and level ground is required for blocking sailboats.
