That bar behind the pilots head is an ideal place to fit a boom traveller. I notice the wheels are fairly upright, is that the way they are going now also?...w
Big yachts have big loads on them, the wheels are probably upright to minimise bearing strain. Talk to any engineer and its well known that bearings are not at their optimum running with a twist in them (like Class5).
Twisted bearings don't survive long if you were running them 24/7 on heavy loaded machinery or a production line.
At one stage I did a lot of work on some machinery that needed to be modified to gimbal bearings for that exact problem.... With fixed bearings the best we would get is 3 months constant use in a high load / high humidity location, I add gimbals, 5 years ago and they are still going strong.
