First season report









Boating season is about over for this year but it has been very enjoyable. The only changes I have made so far to the boat are to move the throttle control over about 1 1/2 inches away from the steering wheel, to allow more clearance, and to replace the plexiglass windshield with auto safety glass for a clearer view. After trying three propellors, we have boat speed up to 33 mph (at a 7500' altitude). The engine trim control allows us to bring the bow down in waves and trim it up in smooth water for more speed. My wife enjoys the boat which is important. She spent more time driving it than I did on this last trip. That is great; my great joy is to start with a vision, create a plan and then make it a reality. This winter I will start on a new boat.

A Trial Run











We took the boat out this weekend and had a great time. We were part of an Antique & Classic Boat Society club get-together. We were surrounded by beautiful traditional mahogany runabouts. I had changed the engine propeller to one with a more aggressive pitch and the result was more speed- 28 mph. The engine was still achieving 5950 rpm, at the top end of its recommended rpm range, and I am wondering if an even higher pitch will bring the rpms down a little and improve speed further. You can see in the attached image that the boat's bow is out of the water at speed. This is due to the slight rocker in the run. By calculation, the bow should rise about ten inches to achieve its planing attitude, and I don't think that is far off. From a visibility standpoint, the bow rise is not an impediment. At low speed the boat rests at its marked waterline. The ETEC engine is so smooth and quiet, and we are still using our first six-gallon tank of gas. My wife is not much of a boater but seems to really like this one. With the intense sun in Colorado, our bimini top is an essential.

Finally in the water!











Springtime in Colorado. After ten days of cold and light snow, the temperatures finally got up in the 60's, and we were able to launch the new boat this week. Everything went perfectly. I had re-enforced the deck at the bimini support attachment points, put flotation foam in the stern, installed a new battery, and readied my list of supplies. Amazingly nothing was forgotten; everything performed as designed; and the setup-launch-retrieval was easier than expected.
