Technically yes. Fair point.
Though I'm trying to answer a general question of size and appropriateness to a new ribber. IMHO once under 6m, especially sub 5.5, unless fully suited up, in anything more than a chop you're getting wet! Much Under 6m and with more than a double jockey so you have seating for >2 there is no deck space for a family to move about, which he mentions.
We had a SR 5.4, great boat for two lads in quite bad weather, but with a family of four it wasn't much fun if the weather turned out in the Irish sea/menai straits. Once you get to 6m, we went to 6.3, in my experience it gets much more family friendly, drier and safer, even when it turns from fair to pretty bad.
