Discussion

As a look at the table above shows, all pictograms in this collection are based on a side view of some sort of boat with at least one wheel below and an element indicating the ramp or slipway. While most variants also display water in some way, a few omit this element and still seem to be comprehensible.

Besides the variants shown here, additional signs exist to warn of a boat launching slipway, as for example the registered safety sign Reference No W044: Warning; Slipway from ISO 7010. In this case the graphic symbol shown inside the triangle is identical to BS 8501 Public Information Symbol No 9082: Slipway.

We could not find any test data concerning graphic symbols for Boat Launch or Slipway in our database, but there is some information concerning comprehensibility of one pictogram available: since all pictograms that failed comprehension testing in Canada have been retired from use there, the Parks Canada pictogram 6-4-217: Boat Launch displayed above must have reached a comprehension rate of 60 % or higher, as this variant does not have the status Retired.

Recommendations

Pierce, T. (1996): The International Pictograms Standard, page 134: Pictogram Boat Launch, Lanchas

As we expect variants showing a side view of a hanger with boat on a ramp to be well comprehensible, we recommend using a pictogram similar to this example pictogram from Pierce (1996): The International Pictograms Standard, page 134.

In the long term it would make sense to develop improved variants and to examine on basis of tests, if a specific kind of rendering has advantages concerning comprehensibility and legibility/visibility.
