I have owned 3 SOTAR boats I am from SW Oregon so they are very convenient compared to Maravia. About 15 or more years ago they did have delamination issues, I had a boat that delaminated. They were excellent about making it right; I was extremely impressed with their willingness to back their warranty it is one of the reasons I purchased other boats from them. They switched to another company for their fabric and those issues are behind them. I had a friend who purchased a raft he was horrible about boat inflation. He inflated one chamber to full pressure at a time sitting while in the hot sun. He did the same thing when he deflated his boat, completely let the air out of the chamber while the chamber next to it was still at full pressure. He did everytime he used his boat I tried to tell him you will blow the internal baffles, but he ignored me. Well the baffles blew he took it into SOTAR and they gave him a brand new boat. I was floored, but SOTAR is really good about backing their product, in this case I really don't believe it was a problem with their product. I am sure Maravia makes a great product as well. Love my SOTAR, their willingness to customize, and their product warranty.
