Questioning a claim about deaths caused by lifeboats

Have lifeboats really killed more people than they have saved?

The claim is questioned and supporting information requested. The exchange does not establish that it is true.

An audience claim suggests that lifeboats have killed more people than they have saved. Supporting information is requested before accepting that comparison. Accidents are acknowledged as the proposed explanation, but the scale required to outweigh lives saved remains doubtful and no figures are supplied.
