Hi Bob,
About your question for the weight limit on the mast and boom to lifting a RIB tender :

In 1986 I visited the Grand Banks shipyard (American Marine LTD) in Singapore. On this occasion, I asked many questions to the technicians of the shipyard, one of my questions was the weight limit of the lift capacity with mast/boom.

The answer I got was very clear : the woody 42' GB have mast and boom made with wood, the weight limit of the lift capacity with wood mast/boom was 200 kg maximum (440 pounds). The fiberglass 42' GB have mast and boom made with ALUMINUM, the weight limit of the lift capacity with wood mast/boom was 150 kg MAXIMUM (330 pounds).

With both wood and aluminum mast/boom they told me it is very important to check the wire tension of the shrouds of the mast before operating a lift.

Fair winds,

Olivier
