Thanks, Roger Ok, Keith and Mark - why are you guys yanking my chain? I’ve been following both of you and your wonderful work for several years now and I haven’t seen any of this hacking you speak of. Your work is top notch. You both are always kind, helpful and supportive to so many of us here at MSW, and a true credit to the forum. And certainly not hacks. Gary

Greetings all, Druxey and Alexander - thanks for your interest in this build and for the nice words! It's so appreciated, and thanks to all for the likes. Plans for this boat came from the Mystic Seaport Research Center. They contain the outboard and inboard profiles, transverse sections, deck and arrangement below, deck framing and the lines. Unfortunately, there is no table of offsets for this boat and even though the catalog lists it - none could be found. And speaking of the boat plans catalog, it is available to view on the Mystic Seaport website, but it isn't downloadable. Here is the link to a digital pdf version that is. Boat Plans at Mystic Seaport - Digital Edition from OffCenterHarbor.com My copies of the plans are quite nice, but as I began working with them, I found the imprints are a little out of square. It's as if the paper sheets had slipped slightly through the copier rolls, not to great extent, but enough to throw what should be straight lines out of whack. Placing a 4' straight edge along a baseline shows the line hooking up or down - a mild curve rather than a straight line, and perpendicular lines veer out of square a short distance from their intersections. Because I imported these plans into CAD for dimensioning and scale printing, the photo process compounded the problem. After much spot checking and obsessing over the accuracy of the skewed lines, I decided to forgo tracing the keel and body plan and instead opted to generate replacements from scratch. This is something of a fool's errand because the differences wouldn't be evident in the final result, even if I were capable of modeling to that degree of precision, which I'm not. But I don't want to begin a new project with inaccuracies already built in. I prefer to create my own inaccuracies and errors, and pepper them throughout the build as I go. I began the process by entering points of intersection on the “half breadths” and “sheer” plans into a “table of offsets” from which to create a new body plan. This was a little time consuming but a straightforward process. First, I created a blank table in a spreadsheet to record all the heights and widths for every hull station. A partial view of that table is shown below. The sheet containing the “lines” is roughly 52” wide by 22” in height, and the greater the distance between any two points on the drawing the more unreliable the measure. So, when I measured the heights of section line crossings at individual stations, I took those measurements from the closest reference rather than the baseline. For the heights, that reference is the waterlines. To assist in that process, I created a macro in CAD that places a measuring ruler between two points of my choosing. It defaults to precisely one foot in length if I set only one insertion point, but it will stretch or shorten to redefine what constitutes 1' when I insert two points. I know the distance between waterlines is one foot, so I set the ruler to span the gap between waterlines at every station where a section line intersects it. In some locations, the default 1' ruler spanned the distance between waterlines precisely, while in other locations it fell short, and I ended up having to define those distances to be 1' by setting the second point. In the example above, the vertical line is station #2 where the #5 section line (buttock) crosses it between WL #1 and #2. In the U.S., offset data points are typically stated in feet-inches-eighths, so this height is 11-6-3 and I entered it into the offset table. I repeated this at every location where a section line crosses over a station line. Then I did the same for the half breadths on every station line where there is a waterline crossing. I also recorded rabbet heights, “bottom of deck at side” and “top of sheer” for every station. I decided to add an extra station between #1 and #2 because I'm concerned about a possible flat spot at that area. So, I struck a vertical line equidistant between stations 1 and 2 and recorded those heights also. I did the same for the half breadths. I created a body plan grid with a center line, horizontal water lines and vertical section lines. Then on to the process of plotting the offset points and connecting the dots with a curve. Below is the added station between #1 and #2 which I cleverly named #1.5. The green lines show half breadth distances, and the turquoise lines are the heights. Then I did the same for all the rest. I did have to nudge quite a few of the points around to obtain fair lines, but not nearly as many as I had anticipated. These nudges in most cases represented 1/4” corrections or less (on the full-size boat}, although I did have a point that was off by more than an inch. And I sloppily made several recording errors, transposed numbers and so on, but those were easy to find. Here's the station curves layered over the original plan sheet. This was before I added the station at 1.5. The match-up is actually closer than it appears because the original is warped in a way that explains some of the differences, but not all of them. Still, after checking and re-checking, I feel confident it will look like a boat in the end. This was an interesting and oddly enjoyable exercise although it didn't practically need to be done. But I'm glad I worked through it just the same. Next comes the backbone. Thanks for looking. Be safe and stay well. Gary

Although I had heard of the RCMP schooner St. Roch, I knew very little about her. After searching her out on the web, I find she has a very interesting history indeed and is a good choice for a scale model. You're doing some very nice work on her so far and I look forward to future updates. Gary

Nice update on the hatch and ventilators, Keith. I hate to display my ignorance in such an obvious way, but what was the purpose of using canvas ventilators over cowled metal ones? Was it to elevate the intake above smoke from the guns? Gary

Wonderful result Alexander, and in my personal opinion, better than what is achieved through CNC. I don't knock anyone for using CNC, but to my eye it doesn't stand up to the hand-crafted artistry that you've shown here. I can't carve for darn, but I admire those how can. Gary -
Valeriy, Denis, Marc and Tom - thanks for the nice comments and your interest in this build. It is so appreciated. Fairhaven is a nice town. In my high school years, the A&W drive-in on route 6 was a regular stop after a beach day with friends on West Island. Yes, it will definitely have some weathering, but nothing extreme, just some honest reality. Well, that’s the goal anyway. Thanks. Gary

Hey Andy, yes a small percentage of the orange guts are saved here also for those same purposes. I’ve not heard of any culinary uses for them though. I can eat my weight in seared scallops and my wife has the cooking technique down, but I’m going to tell her about that chili ginger and garlic treatment - sounds delicious. It’s always good to have you looking in, Paul. Gary

Paul, Andy, Chris, Keith, Roger, Richard, John and Keith – thanks for your warm comments and interest in this build – I sincerely appreciate it and it's great to know you'll be watching. And thanks to all for the likes. I was hoping someone would be able to identify those Coast Guard boats. Never heard of the “Six Bitter” patrol boats, but after a quick search on the web, I found they have an interesting history. Would make a great modeling project - hmm. Thanks Roger. They are shucked on board between dredge haul backs. Only the adductor muscle is kept and eaten. This is the muscle the scallop uses to snap shut its shell halves to propel itself and evade predators (and dredge rakes) that other bivalves such as clams and oysters can't. Once shucked, the meats are rinsed and sacked in 40 pound cloth bags. The sacks are immediately taken to the pens below and put on ice. They are allowed to chill on top before they are totally buried in the ice. This is done to avoid ice melt pockets around the sacks. Because wood can harbor bacteria, the sacks are kept from coming in contact with the pen planks. Atlantic sea scallops are usually less than 6” in height and oddly, their shell is not scalloped. I can't say how modern F/V chill or refrigerate the shucked meats, but it wouldn't surprise me if ice was still being used. Speaking of modern scallop boats, check out this 2019 high-tech New Bedford boat. Viking Power F/V Be safe and stay well. Gary
