Oh! I forgot that they lifted up the middle boat last year, to increase deck space under the wedding that was in Sweden last year. And that RHIB use to be on the port side. The RHIB's is not exactly standard equipment on the boat, if it's onboard then you know that there is a chance that the crown prince is onboard, because he always takes that RHIB with him when he travels!
Yeah I guessed that they might be extra or usually sit on the other side. Since I don draw any real designs myself I always wants to be careful in what I write about errors I see
I didnt konw about that RHIB story so thanks for sharing!
