Explorer operation (2001-10-14)

Just plain old fashioned ordinary hovering.
 
Day started much like yesterday and i was looking forward to go for another drive. Absolutely no wind, not at all. Forecast was good weather for weekend.
 
Day started foggy, but unlike yesterday fog didn't disappear. Well, you can't have both: dead calm and sun shine. At least not this late at fall.
 
It was just me onboard and i was determined to go for a longer trip today. As my father-in-law was going to check the fishing nets i started just before him heading for the bay. Weather called for navigational lights which i put on: flashing yellow, bright all-around and red and green sidelights.
 
River section was just fine, but when i got to bay fog was really thick, like a white wall. Visibility varying from 20-40m (70-130ft). Finally a real chance to check the accuracy of waypoints i created with map software. I stopped the craft for awhile to wait my father-in-law to get there too. I asked him if he thought he could find the place where he put his nets and he assured me that fog is not that thick yet. I had my GPS, he had his lifetime experience exploring these waters. We both headed our ways. Feeling a little bit uncomfortable i steered the craft to first waypoint.
 
As waters got bigger the fog got thicker. It really was a bit surrealistic: all white, absolutely dead calm water and round sun shining brigthly somewhere behind that fog. Before getting to the first waypoint simply fear got better of me and i turned back ! That didn't last too long when i again took the course towards first waypoint.
 
Got there easily and then to the next, and next. These were just some 200-400m (220ft-440ft) apart. Visibility varied on different spots and sometimes it was 15-20m and sometimes almost 100m. I did max. 25km/h, but mostly 10-12km/h since these where put in place with pointing a mouse on a digital map and they can be up to some 50m of from real world. I didn't want to hit anyones summer cottage with 40km/h... That would ruin the day i think.
 
Waypoints where in place, just like i'd imagine they be. After passing number 6 and heading for 7 engine started coughing, just like it did yesterday in the beginning of tour.
 
I turned back right away and this time followed my track back to hoverport. I knew my track was OK so i incresed the speed all i could (engine would not run over 2600rpm) showing 30km/h in GPS. All the way back i had this problem, but got home safely. Couldn't find any problems and after checking the most obvious i did a test drive and didn't have any problems. One idea that was later brought up is that maybe carb is icing. I'm having hard time to believe that since air intake is underneath the engine hood and there is quite warm there.
