There is a summary written by Howard Elliott IJ on the Australian Sailing Rules website. AS will be publishing further info as it is prepared, but Howard’s summary is a very good start. 

There is not an actual presentation, but there are quite a few documents in the "RSS Study Pack 2025-2028" section found here:   https://www.sailing.org/racingrules/

Here's a presentation I gave yesterday.

It's in the context of a review of rules generally and the major changes affecting sailors on the water.
