On the Salona 2270kg is the ballast for the 2.00m draft and 2000kg the one for 2.25m draft. There is a difference of about 400kg on ballast but even considering the difference in ballast the Salona hull is bigger and 200kg lighter.
The difference in ballast is a design option. If you compare the Salona with the French boats you will find that he has much more ballast than those boats (ballast ratio). For normal sailing conditions a more moderated ballast ratio has advantages to sail in light and medium wind (lighter boat), however for offshore work in bad weather it is better a boat with a high ratio of ballast, a heavier boat.
I don't race so I prefer a slightly worse boat on weak and medium winds and a slightly better boat on strong winds and that's why on the Salona 38 I was near to buy I was having a keel like the one on the picture and about more 300kg on a 2.25m keel. Their internal keel structure has no problem in absorbing and distributing the extra weight. There are guys (cruisers) that have put even more weight (on the previous 37).
Another thing i notice is that Solaris gives the Displacement 6900kg vs 7100 for richardbaldwinyacht...
