Hauling and Blocking a Great Harbour 47
Disclaimer – this has been written by Henry Dennig from comments I have collected from various owners. I do not have any engineering background. I would recommend anyone having their boat hauled and blocked, should discuss this event with Ken Fickett before having it done. If you have any suggestions or comments on this post, please let me know – hjd
When hauling a Great Harbour 47, the slings should be aligned with the internal structural walls. The aft lifting point is salon/engine room wall, which is forward of the salon windows, and before the port light.
The forward lifting point is the forward berth wall. Directly forward of the bathroom / office port light. Below the pilot house doors.
Ideally the boat should be lifted with four lifting straps to spread the weight but can be lifted with a travel lift using two straps.
The boat does not have stabilizers, nor spray rails.
The Great Harbour 47 does NOT have a keel. The weight of the boat must be supported around the edge of the boat. Each side of the boat should have five blocks/jack stands. If jack stands are used, they must be chained.
A blocking under the transom and bow can be done after the sides are supported.
