Setting sail - strong rhythm, like sailors working a boat. Feels like it will loop well
Trouble at sea - Same praise here, instruments work really well together, all very balanced levels and reverb, where are the instruments from? I think you could feature the percussion a bit more heavily in this track, any of crash cymbal, snare, bass drum. For inspiration for wind, brass and percussion I would recommend this piece of music by robert w. smith (I particularly enjoy 6:00 onwards)
Really enjoyed the tracks, well done!
