Find attached some pictures from the latest (weekend) trip to the Baltic sea in Germany I 'd like to share. Fun surfing, not so fun fighting the wind 
Fall is arriving here too. Good beach and forest walking though, some flat water paddling on inland lagoon and inlets. The later was surprisingly fast (4-5 km/h, light back wind).
We also tried to tie the boats together using a keel pole. This however resulted in no effect, to my disappointment.
I found the longboat even counter productiv. I measured the speed via GPS and came to the result being faster on my own …
Not to mention the greater manouverability and better pictures Have look if you like:
