Skäreläja is a solid boat from around 1970 and various manufacturers and yards have produced them over the years. It's very hard to find a production number, but I have heard there should be one number next to the gelcoat, but to find that you have to take away all layers of paint. There is no exact number of have many boats that are made, most probably close to 500.
The boat is designed to both fish with or go out with your family, and the superstructure of the boat differs from these two models. The fishing boat version is more square inn it's superstructure. The family had also a possibility to "sail" with both mast and sail. My grandfather had such a boat and once tried it, he told us you have to have patience if you think you could "sail" with that boat...
This one (above) belongs to my uncle and the owner before him was his dad, my grandfather. That's the "sailing"-boat version. But there is a wide range of different sizes of masts, most of them you can't sail with.
One of the newest / latest produced boats is this one (below). The windows are different and also now there's an extra small bridge over the pilothouse. And as you see, no front window in the cabin.
The fishing model of the same boat, with the typical square superstructure are these (below). As you also can see, there is no extra interior in the cockpit.
