The transom looked really ugly since we bought the boat and needed some attention. The red gelcoat was faded, with badly done hole repairs and there was a small vertical crack in the middle. The original plan was to just widen the crack a bit with a Dremel tool and apply a gealcoat filler. But when I started opening up the crack, it turned out that it's deeper than expected. Probably the water got into the laminate at the top of the crack and worked its way all the way down. So I decided to sand all the damaged laminate out.
The Scanmars, at least the SC33 and SC35 that I'm aware of, are infamous of developing a swinging/pendulum keel due to the lack of structural members in the bilge that could prevent the hull from flexing sideways at the hull to keel joint. Here is an article (in Swedish) that mentions this problem (svajköl) and here is another one from a surveyor who claims it's a weakness in the construction. The "stringers" on these boats are only floor beams, that are not going down deep enough to the bilge to act as a structural element. If the boat had harder groundings the attachments of the floor beams could delaminate from the hull, making the hull-keel joint even weaker and the swinging keel symptom worse. When we were on a boat hunt we've checked out almost all the SC33 on the market at the time and paid attention to how their bilges looked like (and in the end bought a SC35 without reinforcements 😄). As the bilge on the SC33 and SC35 looks very similar, I thoug
