Re: Something to hold tiller in place
A tiller extension is a must on the dinghy. You can hold it between your knees while adjusting other lines. I do this all of the time on my 5o5.
A line running between two aft cleats, one on each side of the boat, with a clove hitch going around the tiller works really well. I liked it better than the tiller tamer, which always felt like it was getting in the way and added friction to regular steering.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
