For the last 21 years I've been moving large & small floating objects back and forth from sea to berth(s) and back to sea again. Prior to that I was 14 years in the Merchant Marine, primarily on tankers. High School summers were spent as a Deckhand on tugs in SE Alaska primarily towing log...

At some point in time (prior to the video footage) in the vessels transit some event or events occurred (possibly human and/or mechanical) which placed the vessel in a situation that was non-recoverable. A ship of that size near a berth is typically moving very slowly if not almost stopped...

A quick read of reports says the ship was proceeding to Berth 7 when this happened, does not say where berth 7 is in relation to the small ship it didn't hit or the one further down that it did hit. A few comments / observations - 1) Ship is 1200' LOA and is very light draft, probably empty...

Having ridden SWATH boats in the 50'+ range I can attest they do work well when moving at such speed that all the ride control devices are effective. The longer they are the better they ride. If the ride control devices malfunction you can have unwanted conditions such as negative pitch (bow...

One of our pilot boats had an electrical gremlin that would throw various codes (none of which prevented the engine from running) which were eventually traced to a faulty wiring harness. Once a new harness was installed problem solved, everything has been fine since then. Takeaway is if you get...

If vessel and crew are capable and WX is good going the outside is the easiest way to Ketchikan to start your summer cruise. No tide / current windows to worry about, much less floating debris, etc.

I have the Garmin 1222 xsv plotter, 24xHD radar, AIS B (receive & send) and GT 51m transducer on my 28' Crozier which was built in 2018. Overall I'm very happy with the system. One thing that I would do differently now that I've used the system - The AIS has it's own GPS (heading) antenna...

Of the 5 cruise ships that are homeported in Galveston they are either tied up, at anchor offshore or at a lay berth else where.

"Setting up to run off waste engine heat while underway is a wonderful thing, so I highly recommend it if at all practical." Also if you set-up the heating system to keep the engine coolant / engine warm when not underway you will always have warm coolant = :) engine. All of our tugs are...

I have Seahawk bottom paint on my 28' aluminum boat. Best to sand blast hull then apply barrier coat then bottom paint. You must use aluminum alloy anodes otherwise the anodes on your outboard will be doing all the "work". A zinc anode on aluminum hull in salt water does not protect at all.

110' LOA, Built in 1943.

"I think the next big evolution will be going to high voltage DC. And I'm not talking about 48V. I'm talking about somewhere in the 100V to 300V range. That would bring current way down, and I think ultimately be much safer, even at the higher voltage." My fathers boat, former USN WWII...

"Crossing an ocean as a journalist is exciting three times. When you depart and when you arrive and when things go wrong." This pretty much sums up ocean crossings - after x number of days watching the water go by it can get pretty boring. Granted there is great sense of accomplishment upon...

https://oceanplanetenergy.com/ Lots of good info on Li and carbon foam batteries.

In the winter months there can be a very strong current flowing perpendicular to the docks in Cozumel, this in conjunction with a north wind creates a situation where the ships combined thruster power cannot overcome the current & wind - as clearly demonstrated in the video. In Mexico the...

Hard to imagine the boat sinking just from water in the toy garage unless the WT door was leaking or there was a major systems or structural failure.

If the dinghy garage was the source of the water ingress and sinking I wonder if that would be viewed as a latent defect by the underwriters?

Hopefully it is insured with an Agreed Value Policy.

Any updates on the build?

Flume Tanks is a system of controlled flow of water from one side to the other - it is occasionally seen on ships. Gyro's tend to work best on lighter hulls. Active fins tend to work best on heavier displacement hulls.

We get 20,000 to 22,000 hours out of our KTA / QSC 38's. Admittedly these are big engines but have proven very robust. Aside from basic maintenance, injectors around 10,00 hours and heat exchanger plate cleaning annually. Note - this is in GoM where summer water temps can reach 90 F., in...

I've found that Clorox does a very nice job of cleaning the tank, I run it through the toilet and the pump out line, let it slosh around some then pump out.
