    Zincs on 34' CHB Tri-cabin Trawler

    I have a 1978 34ft CHB Tri-cabin Trawler with a single Ford Lehman 120 engine and a Side Power bow thruster. How many zincs are there (or should there be) on this boat and where are they? From above the water, I can see one slab on the stern under the swim deck and one disc on the rudder...

    Ford Lehman 120 Stainless Steel Exhaust Elbow

    Arrrggghh!!! Me, too! Wish I had known. Completely baffled me how an engine design engineer could choose cast iron to have high temperature gases and salt water run through it. Mine was swiss cheese. I thought I had a fire in the engine room.

    Physics question - which line method is stronger?

    Knot relevant No one has yet mentioned that the B configuration contains a knot. It is well established that knots reduce the breaking force on ropes. In Mountain Rescue, we use a rule of thumb that a knot in the system reduces it by 50%. On that basis alone, configuration A has the greatest...

    CHB Clearance

    Don't forget water level changes I have a CHB and there is another one in our covered marina, along with other Trawlers. All of them have their masts down while berthed. I am going to be a bit surprised if anyone makes covered slips tall enough for Trawler masts. Regardless, don't forget...

    Star Board Tip?

    Another +1 for Tap Plastics. Just got a piece there and they shaped, too. Not cheap stuff, though.

    Super Bright Waterproof Flashlight

    Not sure Pgitug had a $125 flashlight in mind, if you are talking about this one: https://www.amazon.com/BigBlue-AL1200N-II-Lumen-Narrow-Light/dp/B07KDY6SQ8/ref=sr_1_2?crid=EXLZ47YRJFZL&dchild=1&keywords=big+blue+1200&qid=1610392330&sprefix=Big+blue+1200%2Caps%2C208&sr=8-2

    2nd Depth Finder

    Take the box off and look for a nameplate, label, sticker, etc. I only see one screw holding it down and it looks like easy access. If you find some markings that will help us identify it, take a photo and post it. If it has no markings, it's likely homemade. In that case, open it up, take a...

    Open vs. Covered Moorage

    Sorry, I tried to read all these responses to make sure I didn't repeat anything, but there are too many. Here's my list: Pro Easier to work/play above decks. You're in the PNW. It rains all the time. Less rot, mold, leak, etc. Water is the universal solvent. Less sun damage. UV radiation...

    What through hull transducer is this?

    What is this through hull transducer on my 1978 CHB Trawler? It's not OEM from the looks of the installation. I assume it is the depth sounder but it doesn't look like any that you can purchase these days. If it is the depth transducer, is there any hope of using it with any modern display...

    AIS receive-only for CE laptop?

    Depends on your definition of cheap. I consider this cheap: Get this marine VHF radio, with built in GPS, Emergency MMIS broadcast, and NMEA2000 output ($408): https://www.amazon.com/gp/product/B089YV4XYQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Then get this NMEA2000 bus starter kit...

    Who has lowest cost insurance?

    We have the same (BoatUS/Geico) on two boats in Washington State, one of which is a 34' Trawler, for which we pay about $450 annually. They required an in-water survey which also cost us $450. We also looked at Progressive, which did not require a survey at all, but the quote we got was about...

    Drawing programs

    For what you want to do, CAD programs are like swatting flies with a sledgehammer. You should probably be looking at drawing programs. Take a look at Draw.io (http://draw.io/). It's simple, free, web-based, and integrates with OneDrive, DropBox, Google Drive, etc, and has a rich set of...

    S&M in Seattle

    No, it's a little farther west, on the other side of the University Bridge. Literally across the street from Voula's.

    S&M in Seattle

    We're in the triangle formed by the I-5 bridge, the University Bridge, and the north shore of Lake Union, where the marina is. It's called the Washington Boat Center.

    S&M in Seattle

    I forgot to mention that it has a bow thruster. I am told the without it we would never get it in and out of the slip we are in. We decided to move to a bigger slip on the other side of our marina where there is twice as much room to get in and out.

    S&M in Seattle

    My wife, Marilyn, and I recently purchased a 1978 CHB Trawler on north Lake Union in Seattle. It is our first power boat of any kind, however, we have been sailing a San Juan 23 for about five years, and crewing on other people's sailboats for years before that. My job and the sailboat are...

    USCG vessel documentation scam warning !!!

    The horse that I am riding has not been beaten to death, namely that unless your buddy, your daddy, or a forum like this forewarns you, these parasites are gaming the ease of electronic transactions via the internet to screw people in a way that should be illegal, or at least made impossible by...

    USCG vessel documentation scam warning !!!

    I recently purchased a “documented vessel” and in the process of renewing and transferring the documentation to my name was scammed by a company pretending to be an agent of the United States Coast Guard (USCG), which is the agency that controls national vessel documentation for the USA. Since...
