Very nice boats. I have been lobster fishing with one of the tresfjord“fishing” editions. It have an open stern deck and is purpose build for costal fishing. Very nice boat. As previously mentioned with the saga it rolls a lot in side winds but is a very seaworthy and nice small boat
Yes it has basically the same characteristics as all other boats that we in the Scandinavian countries call “snipa” or “snekke” . They roll a lot but have other advantages. It will work nicely in the canals and in the Serbian river. No problem with that. These are fishing vessels build for coastal fishing in the nordics. No blue water cruisers.
