I live on a small island (Full time population ~4,000) off the coast of Vancouver, BC. We have a yacht club which has narrowed it's focus over the years to a racing series and an educational program for kids. Membership (and, of course, funds) has declined as a result. Several people are trying to broaden the programs offered to revitalize the membership, funding, and overall interest in the club. One program being considered is a educational/social series where we would invite guest speakers to talk or hold a short workshop about a boating topic of interest, followed up with a video about a boating adventure or another topic of interest, followed up by a social hour ... "finally we drink!".
The question is, what is an appropriate honorarium for someone to come visit us and do a presentation? There is a bit of time overhead to get to and from the island (15 minute ferry ride plus queue). It seems a lot of people who do such things have something to "sell" (i.e. a service, a book, a product, a marine store, etc) so they derive a non-monetary benefit. It's obviously a small market and a fun place to visit. It seems that the overall compensation needs to be attractive enough to entice someone here. In the same breath it will need to be modest enough that people feel a value in attending for a small "cover" charge... and, of course, something our modest club can afford to subsidize if necessary.
Thanks in advance for any feedback, especially from those of you who might be doing something along these lines already (either as a club or as a presenter).
