CONTINUOUSWAVE

The specifications for the Boston Whaler TENDER 9 are listed in the REFERENCE section article that gives specification and dimensions for many Boston Whaler boats. See

http://continuouswave.com/whaler/refere ... tions.html

You'll find the maximum recommended power is 5-HP.

Due to some problems with ground equipment at the launch pad, the GPS IIF-11 launch has now been postponed to Saturday, October 31, 2015. The launch window opens at 12:13 p.m.

Regarding the cockpit sump drain to the sea: if the trim on the boat at rest is such that the water coming in via the sump drain is always contained in the sump, I'd leave the sump drain open to the sea when on the mooring. The sump pump would then be set to OFF.

If I were leaving my Boston Whaler boat on a permanent mooring, I'd want to have two pendants from the mooring ball to the boat. One pendant would be set shorter so it would take up the strain initially, and a second pendant set slightly longer to take up the strain in case the first pennant failed....

To the best of my knowledge, all the center console assemblies used in Boston Whaler boats are custom fabricated and molded by Boston Whaler themselves. An OEM replacement could only come from Boston Whaler. The usual policy of Boston Whaler is to retain the molds for boat components for ten years a...

I think the most likely problem for recreational boaters with an AIS Aid to Navigation (AIS ATON) will occur in their chart plotters. The chart plotter must be ready to receive AIS MESSAGE ID 21 (AIS AIDS TO NAVIGATION REPORT). AIS Message 21 is a complex message. For details see http://www.navcen.u...

Regarding a radio receiver that tunes to the AIS frequencies: the receiver is already quite neutral about where the stations that send the signals are located. It doesn't care. It is just a radio receiver, and it will receive a signal from a land-based station sending AIS ATON data just as well as i...

Regarding how an AIS Aid to Navigation should be displayed, there are recommendations for the appearance of the icon or graphic representation of such an aid to navigation for display on an electronic chart plotter. For more information, see SYMBOLS FOR AIS ATON http://www.nauticalcharts.noaa.gov/mc...

A nautical mile is generally considered to be one minute of latitude, or a distance of 6076-feet. A statute mile (in the USA) is 5,280 feet. The conversion factor for changing knots or nautical miles per hour into miles per hour is thus 6076/5280 or 1.151. If a boat speed is said to be 35.1-knots, t...

I have not tried the mounting method using the RAM brand of gear. One reason: the mount costs as much as some chart plotters these days. I find having a chart plotter mounted on the dashboard with the usual bracket mounting has this added benefit: it creates a space behind the chart plotter where yo...

I was surprised by the mention of the SHOPSMITH. I remember seeing television programs back in the 1960's about the SHOPSMITH. Today we would call them Infomercials, but back then they were broadcast under the guise of do-it-yourself shows. I would not have expected the SHOPSMITH to still lumber on,...

I don't know and have not speculated about the size of a wave that would be necessary to cause the LEVIATHAN II to capsize.

Cracks in gel coat layers usually occur due to stress or movement of the layer. They tend to occur in areas where the gel coat layer has been laid up too thickly. I don't know of any easy method to permanently and cosmetically repair hairline cracks in gel coat. Since the goal of the repair is impro...

Are you sure the c.2008 Mercury 60-HP BIGFOOT has fuel injection? Is there a throttle position sensor? If so, then perhaps the throttle position sensor has become intermittent at the lower throttle setting positions. Do you have the factory service manual? If you are attempting to make a diagnosis a...

A change in the engine trim could affect the engine running characteristics in two ways: --running the trim motor adds a load to the engine from the electrical power being generated by the alternator, and --the exhaust back pressure can change if the through-hub exhaust flow decreases from too much ...

As related to measurement of sound, many people employ the term decibel without really understanding its meaning. The best definition of what amount of sound change occurs when sound is decreased by 1-deciBel is given in this humorous example: Q: When you ask your teenager to turn down the volume of...

Does this vendor have the OEM replacement rub rail components in stock for classic Boston Whaler boats?

FRANK--did you cut off the upper part of the boat hull or the upper part of the jack plate?

Which REVENGE hull do you have, the 19 or the 21?

The term "rogue wave" seems to be imprecise and quite poplar among non-mariners and journalists. In any well-developed sea state, there is a statistical probability that a wave of about TWICE the height of the "significant wave height" will occur once every 1,000-waves. Note that...

This launch is still scheduled for October 30--that's tomorrow. Don't forget to watch the webcast. The launch window opens at 12:17 p.m. EDT.

There is a previous report on the performance of the Yamaha F115B on this1988 Boston Whaler OUTRAGE 18 in a thread from the old forum. In that previous report the boat speed was reported to be (32.5-nautical miles per hour or) 37.4-MPH. It appears that by raising the engine mounting height one hole ...

That is not my interpretation. As far as I can tell, if you have a full-transom boat, or what they call a SEA DRIVE option in the owner's manual, the boat will have a sump pump. And you leave the through hull drains plugged because you don't want the pump to run continually. I don't quite understand...

David (aka HOOSIER) did not go back to the launching ramp he launched from. That ramp was at the extreme northern end of Mullet Lake, and it would have taken David three or four hours longer to get there. David wisely took the advice offered by Christine to just get back to the launch ramp in Indian...

Here are the factory specifications for the 1993 Boston Whaler OUTRAGE 21 boat:

LOA = 20' 9"
Beam = 8' 6"
Draft = 14"
Boat Wt = 2,500-ls
Max Wt Cap = 3,755-lbs
Swamped Cap = 6,000-lbs
Person Cap = 11
Max HP = 300
Min HP = 150
Rec Shaft Len = 25"
Fuel Cap = 122-gallons

I believe that the c.1993 OUTRAGE 21 uses a hull mold that is very similar to the popular 21 WALKAROUND cabin boat. If that is true--I think it is--then I would hesitate to have only a 150-HP engine on the transom, and particularly hesitate to have only a 150-HP four-stroke-power-cycle outboard engi...

The USCG Local Notice to Mariners (LNM) was just sent today. It announced many more conversions to Synthetic AIS AtoNs or Virtual AIS AtoNs, including many aids in my local area, the Detroit River, Lake St. Clair, and Lake Erie. Here is an excerpt from the LNM: ATON DECOMMISSIONING Lake Erie - Toled...

Have you read the REFERENCE section article on the Boston Whaler 15-foot hull ? Have you read the section of that article under the subheadings "Dimensions and History" and "Description" ? That article first appeared in 1999. I don't know that I have any other information on the ...

The voltage drop in a conductor that feeds a secondary power distribution panel from a primary power distribution source will typically not be affected by outboard engine starting currents because typically those currents do not flow through that conductor. In the problem being analyzed in this thre...

The use of AIS synthetic or virtual aids to navigation is not restricted to the Great Lakes, and, in fact, that is probably the opposite. AIS ATON devices have been in the process of being deployed at many coastal areas, and the are just now coming to the Great Lakes. The use of an AIS ATON at the M...

The capsized boat was the LEVIATHAN II, a 65-foot vessel. The tour operator's website gives some details:

Yes, but the whole point is to know if your display shows targets other than VESSELS.

For example, does your display show AIS BASE STATIONS? Does it show AIS Aids to Navigation?

FURUNO has announced a rebate program that offers a $200 rebate on the purchase of: --GP1870F 7-inch Chart Plotter and Fish Finder with Internal GPS/WAAS receiver --GP1760F 5.7-inch Chart Plotter and Fish Finder with Internal GPS/WAAS receiver The MSRP of these products are: --GP1870 = $995 --GP1670...

My concern is for the chart plotter display of AIS data from an Aid to Navigation (AIS ATON). Most of the chart plotters out today are really intended to show other VESSELS on their AIS display. I suspect they may not be ready to show AIS AtoN targets. I would like to get some reports from users of ...

The best solution to the very common problem of electronic devices on small boats being re-set or rebooted when the outboard engine is started is as follows: --install a separate battery for use with the electronic devices on the boat --isolate all electronic loads to the separate electronics batter...

I believe that the KEVLOK battery hold-down straps used on classic Boston Whaler boats were custom assemblies made from components manufactured by AGM CONTAINERS. AGM CONTAINERS has a website that shows their custom assemblies: http://www.agmcontainer.com/tie_downs/customassemblies Can you give the ...

No one can know how your boat is wired from your description of the behavior of your chart plotter. What is evident: the battery voltage is sagging too much during engine cranking. The remedy: reduce the voltage sag in the engine cranking battery during engine starting. To reduce the voltage sag in ...

A repeat of my earlier question: Does your chart plotter display synthetic or virtual ATONs created by AIS transmissions?

Regarding how to handle the plugs for the through-hull drains, see the owner's manual:

The gel coat layer in a Boston Whaler hull built to workboat specifications (or a red dot hull) is not likely to be particularly thicker than in a regular hull. The portion of a hull built to workboat specification that is thicker are the layers underlying the gel coat layer. A thick layer of gel co...

The NTSB report explains the cause of the capsize and deficiencies in the ballast, the launching method, and the trailer.

Based on a drawing contained in the owner's manual on the folio marked Page 10-4, the four switches on the dashboard of a Boston Whaler SL 16 boat were for --Navigation lamps --Instrument illumination lamps --Bilge pump --Accessory circuit Those four switch functions are the same as my earlier specu...

Thanks for that great link to an index of old Boston Whaler owner's manuals that are available on-line. I added that information to the REFERENCE section. It appears that the owner's manual for a c.1990 Boston Whaler SL 16 is found at http://media.channelblade.com/EProWebsiteMedia/2904/Owner's%20Man...

This discussion is a bit tangential to the usual strictly boat oriented topics, but I would like to solicit advice from the cadre of wood-working experts that read this forum.

Considering the EPA regulations that prohibit the tampering with any part of a regulated engine that can affect exhaust gas emission, it seems possible that you might not even be able to buy an ECM without demonstrating that you had the appropriate model engine for its use. The easiest way to increa...
