Hi James,
This is an option if you are happy carrying about 48kg sailing weight.
In over 5 years I have found little need to try doing this, although I do see it as an interesting option for sailing to somewhere, like to a pub lunch or beach picnic!
Instead, if necessary I would tip the RS Aero over in thigh/waist deep water after launching whilst I deal with the launching trolley. That buys a lot more time than leaving the boat upright.
