All of these trade names and acronyms for trade names of various SONAR methods just keep me confused. I think the acronym HDI is an acronym for hybrid dual imaging, as mentioned above. But this is an awful use of "HD" because Lowrance uses 'HD" to mean high-definition, and they call a...

A much simper way to get a pair of BEARCAT 85 engines on the transom of your Boston Whaler OUTRAGE 21 would to buy a pair of E-TEC 90-HP engine and repaint them to look like a Bearcat. Add some Bearcat decals and cowling decorations. You'd have the look you want, and the modern outboard engine power...

About a year ago, an article in the old forum discussed the multiple legal actions going on among five electronic manufacturers defending their patented methods regarding SONAR techniques. GARMIN was a favorite target as it was getting sued by three of its four competitors. JOHNSON OUTDOORS, the par...

In case you were wondering about the two devices, Elite-7Ti and Elite-5Ti, that are listed above as being compatible with the TotalScan transducer, those yet-to be-seen products are apparently something new and in the works from Lowrance. They should be announced this month. A Bass Pro Shop website ...

That submarine screen capture is amazingly good. That is not side scan--what made that image?

It sounds like the WiFi base unit in your HDS Gen3 must have taken on a different ip-address. If you have other WiFi devices around, that address migtht already be in use. Another common address is 192.162.1.254.

What was the ip-address that you found the WiFi base was using?

I found nothing on the top page of that Antique Outboard Club's website about a BEARCAT 85. It seemed to be a page soliciting people to pay to join an organization, not a source of information on a BEARCAT. The BEARCAT 85-HP four-cycle outboard engine is mentioned in my article about BEARCAT outboar...

Epoxy is a better adhesive for making repairs. Use of epoxy does not lead to failure. Epoxy is not mumbo-jumbo. Epoxy is fabulous for bonding wood. A reason boat builders do not use epoxy for laminating is the higher cost. Cost-no-object boats are put together with epoxy. There is no reason to esche...

Is it possible to summarize what will be seen in this six-minute long recording?

That OUTRAGE 18 with the E-TEC for $18,000--wow that was a deal. And a very interesting, one-of-a-kind modification.

NAVICO, the parent of Lowrance and Simrad, have announced a new SONAR transducer they are calling the TotalScan transducer. They describe this transducer as an "all-in-one transducer that matches [their brand of frequency modulated pulse compression] SONAR with StructureScanHD and DownScan Imag...

I don't think there are any advantages to having a c.1985 OMC Sea Drive engine on a Boston Whaler today. The outboard engines would be old, conventional, smokey two-stroke-cycle engines with very little sophistication, and the mounting system is rather large, heavy, awkward, and probably completely ...

The term SEA DRIVE is an OMC term for their outboard engines with an unusual mounting configuration. Boston Whaler boats could be ordered with a closed transom for installation of a Sea Drive. This option was called a Sea Drive Blank transom, meaning the transom was closed off and ready to have a Se...

On the NOAA ENC chart, the green can is indicated as having a fog signal, a gong. Here is how the official NOAA ENC chart US5NY19M appears for that same location: NOAA_ENC_Chart.jpg The chart was rendered in POLARVIEW NS, a very nice chart plotter application , and, by the way, available for the Mac...

Using a calculator at http://resource.npl.co.uk/acoustics/techguides/seaabsorption/ for a frequency of 400-kHz, and for the typical seawater values for salinity, pH, and temperature, the attenuation of sound due to absorption was calculated to be between 94 and 98-dB per kilometer. Converting to dB ...

The best way to set the winch position is to adjust it to fit the bow stem of the boat as loaded on the trailer. Get the boat loaded onto the trailer with the orientation you want, then move the winch post and winch position on the winch post to fit the bow stop roller and the winch to the boat's po...

I have seen the designator "Gulf Coast Edition" on a Boston Whaler boat. I think it was some sort of equipment package or bundle of options.

If a side scan SONAR transducer is operating in 6-feet of water and tries to get an echo from an target that is 60-feet away, the cone angle echo coming from the object 60-feet away and on the bottom relative to straight down to the bottom would be ARCTAN (60/6) = 84.3-degrees The distance to the ta...

To ftp with MacOS, just open the TERMINAL application. Then use the ftp command

ftp 192.168.1.1

to connect. For user-id use anonymous, and for password try blank password.

Re how an AIS Aid-to-Navigation (AIS AtoN) should be displayed, the recommendations are given at http://www.nauticalcharts.noaa.gov/mcd/updates/ais_aton.html For electronic charts in vector format (ENC) the cited reference says, "NOAA charts will depict the AIS signal with a magenta radio circl...

With a BEAM of 8-feet, the hull of a 190 MONTAUK will probably not be able to fit between the fenders of a boat trailer that complies with the usual restriction on width of 8-feet 6-inches. This means the height of the boat on the trailer frame will have to be set so the chines of the boat hull are ...

Thanks for posting the screen captures of a Lowrance HDS Gen3 showing AIS AtoN targets. Below is the most interesting screen capture, showing both the chart plotter's icons for the aids and the AIS AtoN icons for the aids, overlaid. The use of radiating magenta lines apparently is suggesting a radio...

I believe that the general feeling here is as follows: the best way to avoid hydro lock problems is to avoid situations in which they are most likely to occur, such as yanking the throttle-shift from FWD at on-plane speed to REV at nearly idle speed. That situation is likely to result in a stalled e...

If the reports from other users are correct, you should be able to ftp to 192.1681.1.1 and see the files. There are a zillion ways to run an ftp client. I don't know which one you are familiar with. What type of computer are you using? Mac/Unix/Windows?

For information on rub rail replacement, see the REFERENCE article on RUB RAILS. This is mentioned in the FAQ. Reading the FAQ is also recommended. It has good answers to many frequently asked questions.

The two separate threads on this topic are now merged.

You might also enjoy listening to an interview with Jim Watson of WEST SYSTEMS that I conducted 15 years ago. It can be found at http://continuouswave.com/whaler/radio/ The irony of this 15-year-old interview: 15-years ago having audio content on a website was so far ahead of most peoples' computer ...

Information on HDOP is available from Wikipedia.

While it would be handy in some situations to be able to make a DSC call to an AIS target--like a big ship bearing down on you at night while your boat was encumbered and could not maneuver--the big question is would the ship answer the call? In the Great Lakes all commercial traffic is supposed to ...

If you are in only 5.7-feet of water I would not expect the range of the side scan to go very far. Isn't the range of the side scan SONAR related to the water depth?

ASIDE: You should be able to get a much better image of the screen by using the built-in screen capture utility.

The restoration of an older boat that is no longer in pristine condition can be characterized in two general facets: --making repairs that are solid, durable, strong, and waterproof, and --making those repairs undetectable in the boat's appearance. Some restorers go to great lengths in the cosmetic ...

To learn about making repairs to a Boston Whaler boat hull, I recommend the following articles for your reading: -- Repairing Hull Damage the Whaler Way by Taylor Clark, a great article with many illustrations; -- Instructions--Hull Patch Kits , a reproduction of some concise original literature fro...

The accuracy of a GPS receiver position solution is mainly dependent on the particular location of the receiver and the position of the satellites used in the position solution at that instant. Without getting too technical, the more satellites in view and the more favorably their lines of position ...

Being able to initiate a digital selective calling (DSC) call to another vessel that has been discovered by its automatic identification system (AIS) broadcast containing its maritime mobile service identity (MMSI) by using an electronic interface on the display of chart plotter to control the radio...

Lowrance GEN 3 device have a WiFi base unit included, and, apparently--I have not tried this myself--they also have a FTP server built into the device. This means that one can wirelessly connect to the GEN 3 device and use the FTP protocol to transfer files between the GEN 3 FTP host and a connected...

PORTHOLE's comment on AIS target display: "Listed on the HDS vessel display were all of the Ambrose Channel ATONs in the New York Harbor approach." That is very interesting. I was curious about the ability of the NAVICO chart plotters to display AIS Aid-To-Navigation targets. Perhaps you c...

To learn about the history of the Boston Whaler 18-foot hull, read my article about that model in the REFERENCE section. See http://continuouswave.com/whaler/reference/18Outrage/ To see a nicely re-powered GUARDIAN 18 with E-TEC 150 H.O. power, see http://continuouswave.com/forum/viewtopic.php?f=4&a...

In some instances in which a standard Boston Whaler hull has been adapted into commercial or government service, it has been seen that the transom height has been RAISED five inches (at the factory) to 30-inches as an factory option, but I have never heard of any instance in which Boston Whaler offe...

There are FIVE articles in the REFERENCE section on trailer selection and set up. The index to those articles is at http://continuouswave.com/whaler/reference/trailering/ If you read those articles you will have a good background for setting up a trailer to carry your Boston Whaler boat. They will e...

I believe the mechanism by which the VERADO engine discussed here was damaged can be described as follows: --the propeller turned the propeller shaft for forward propulsion; --the shift was in REV; and --the engine was stalled. Therefore, because the propeller was turning for forward propulsion whil...

I do not recommend filling the transom splash well drain holes with rigging cables.

Jeff--thanks for posting that brochure from HiLiner.

I see a lot of resemblance in their SWINGER model to the later Boston Whaler TEMPTATION boats.

The most important aspect of an electronic chart plotter is the electronic charts. You should first determine which brands offer electronic charts for the water you will be operating on. There is no point in getting a particular chart plotter if there aren't any good charts available for it for your...

When I was first in the market for a larger Boston Whaler boat, there was a Boston Whaler YANKEE VOYAGER 22 for sale locally in southeast Michigan. Sometimes I wonder how my Boston Whaler ownership might have progressed differently if I had bought that boat. It seemed to be in very good condition. A...

There is nothing intrinsic in a four-stroke-cycle engine that causes it to behave differently. No engines run without fuel or start without fuel. Your inquiry is really about priming the fuel system of an engine before attempting to start it. Review the operating instructions for your outboard engin...

Someone hacked up that boat's transom.

I have a 1992 Boston Whaler boat. There are no cracks in the gel coat of the hull of my boat.

It is my experience with Boston Whaler boats that the hulls seen in your pictures are very unusual examples of Boston Whaler boats, and they are not representative of what one can find today in c.1990 hulls.

I do not see the size of the boat as having an influence on the decision to use electronic remote throttle and shift controls. The price of the controls is probably the more important aspect of the decision. Electronic throttle and shift controls with some sort of intelligence are usually an expensi...

Jeff--that is a great picture. Who took it? It seems to presage a journey into the mists.
