Spent over 20 years working for a TowBoatUS tower. If a boat has a bow eye, we use that. Small boat bow eyes are supposed to be able to hold the boat vertical. Cleats on bigger boats. The problem with cleats are the lack of through bolting or backing plates. Of course with any of the hardware, prope...

Question to Lowrance tech support:
Where do I find these demo files to try with the new 3.0 software updated on my HDS7 Gen 3?

Well most of your comments are above my pay grade :-) How accurate do you think the device displayed error is?

You can see in the picture I posted, mine sits on a keel roller with no problems. Granted it is only a 15' boat though. Haven't decided yet if the 21 Outrage is going to get one, but if I do put one on, the odds are good it will also be on a roller. But with the 21 being significantly heavier I woul...

the one thing that stands out the most is don't attach it where the strakes join the bow edge under the bow eye, go below that area. Also, follow the instructions to the letter.

At that price point I would opt for a conventional sport fisher, either an express or flybridge with twins.

One of the things I like is the easy install for flush mounting. But, that is not without a drawback. These pictures were taken as I did the removal.

I'm hoping cutting the post down a little over 5" and moving it back some will help. That and the addition of a power winch that will "power out" ought to help ease some of the drama during launch.

That was the first time I used the HDS side scan, and I only had an hour or so to try it out.

porthole

The center part of the side scan display only shows the depth right under the boat. It can't show the depth for targets that are 60-feet away--at least I can't see how it could with the presentation we are seeing. I never suggested that depth of targets 60' out could be read. I only said that while...

The 5.7-feet comes not from the left-right side scan presentation. It comes from the downscan presentation, seen in another window. There is no depth information in the left-right side scan presentation. Yes I know, maybe I was a little to generic in my wording. The 5.7' is coming from the TM150, s...

The outboard was tilted enough to not interfere with the side scan beam. The screen shots on this post - the starboard, darker side is shallower water, in about 100 horizontal feet or less it goes from the displayed depth to zero. http://continuouswave.com/forum/viewtopic.php?p=1811&sid=f7ade5e1...

Right off the Jersey coast, we have a Stolt tanker the "Stolt Degali", that was a victim of an at sea collision in November 1964 [52-years ago]. The SS Shalom sliced the Stolt Degali stern section clean off. It has become one of the premiere NJ wreck diving locations. http://njscuba.net/si...

So, two ships collide in Singapore, one sinks. Since both were equipped with AIS we have a interesting youtube video:

My own inboard boats and every inboard I ran had a simple digital depth gauge. Always on, no adjustments other then setting the keel offset. We always used a through hull transducer on the bigger boats. If my boating was what you described, I would add a simple gauge, thru hull or transom mount.

Having done a repair or two below the water line and helped with above the water line repairs (spray "finish" required), I thought it was an OK video. If you have a fear of attempting a repair, the procedure shown can help you give it a shot. As long as you don't grind through the hull, an...

"Smack and pull" is a way I have done many many times in my former career. But, I would not use that method on either a cable or hydraulic helm.
Even the much heavier automotive steering columns can easily be damaged with that method.

It just might, but I would probably need a bow and stern unit. Kind of a narrow fairway with limited room at the ramp.

Thank you. Will try again tomorrow. Soaked with WD-40 tonight WD-40 or any penetrating oils are not going to help, it is an interference fit and there is zero clearance.

Steering wheels are on a tapered shaft. If the nut was cranked down to hard it will be very difficult to remove. Taking the helm apart will not help if your goal is to remove the wheel. What kind of puller are you using? A puller with three-jaws will be best. Set up the puller; put the nut back on t...

Hmm--since the Lowrance pilot will, according to the manual, keep a boat on station using a linked trolling motor, this is certainly on the cool factor.
