I try wherever possible to tailor my talk to appeal to the audience and make it more applicable to their particular interest. For example, when talking to boat clubs the talk can become more nautical, talking to motor or train enthusiasts I can deliver more technical detail of the boats.
At many presentations people approach me with enquiries about lifeboats, old and new, that they have a particular knowledge of or interest in.
If you could feed me with as much information as possible regarding the enquiry before the event then I may be able to bring the information with me.
The RNLI has 190 years of heritage and does have extensive records of its operations and lifeboats.
