Why didn’t you communicate each morning about your plans for the day? And at the end of the day, review the days paddling? Communication is key. Speak your concerns to your paddling partners. Plus each paddler should have their own map. I’ve paddled with faster paddlers and make them wait until I am rested. I don’t accept “mock paddling” as you did. And when I paddle with slower paddlers, I wait until they are ready to continue paddling. With time and with more group trips, you’ll get the hang of it. Good luck!
