Re: is it safe to adjust tilt and trim at any speed?
In my perfect world we would always have calm seas gentle winds and relatively flat water and an abundance of fish and they are always willing to bite. Ok, nuff said about that, the real idea as stated before was effiency on the water. On a calm day anyone can look good, but when you have a rough go of it, learn to read the water ahead, and be ready to back down if you see a larger wave approaching. They do run in sets for some reason and from my experience it would seem the 6th to 9th will be larger. Never asked and don't have a clue about that. It's much better to trim down and run then to just back off and plow. Just don't try and see if you or your boat can take the most abuse. The boat will probably win but it won't do it any good.
Just an opinion
Safe boating ya'll
