New Moth MKII semi scale yacht
Haven't built anything for a while due to lack of space (too many models) but the urge to build something was too great. After looking at many options, I decided to go with something 'easy' to build. I found some full size plans for an Australian MkI Moth which I'm building to a MKII (double chine) style.
I'm building in foam and glass again to make things easier. It's 850mm long and 310 wide which is roughly 1/4 scale (original is 11 ft)
Started by converting all the lofting measurements on the redrawn 1953 plan to metric and dividing them by 4 to get the scale.
Next was creating the ply deck, then contact gluing onto it a piece of dense 50mm building polystyrene. This was then shaped with a surform file and the chines shaped afterwards using eyeometry. Then the 10mm deck foam was glued on so the deck sheer could be shaped.
Next the cockpit foam was routered out, and basswood sides and inner transom piece epoxied in. After that, the ply outer transom piece and hardwood nose block was epoxied on.
The centerboard case upper and lower ply braces were routered out (using the mill and a 1/2" slotting bit) large enough to accept the case sides, leaving enough room for the 6mm aluminium keel (can't use a centerboard for obvious reasons) which will have to have a bulb fitted.
A rebate in the bottom of the hull was routered out for the lower c/board brace. These braces are needed to form part of a box structure with the floor and cockpit sides which the c/board can lever on. Once everything is eventually glassed in, it will make it very strong unit, so the foam will just be the shape surrounding the box, and not having any strain put on it. The ply deck will take the strain of the stays/mast.
The cockpit floor was cut, and will be slotted the same as the braces, then the c/board case will be built.
The mast on this is 1.486m tall, - sail is -luff -11.295, foot 609mm, so quite large for a small boat. The full sized boat is a lot of fun to sail, so this model will be interesting to sail. Unfortunately, without the human input required, and being a performance boat, it may assume the attributes of a submarine in a stiff breeze, - time and testing will tell.
The basic mast was made from 12mm ally tube, boom from 10mm. Sail pattern was cut from art card to the plan. All laid out on the floor to get an idea of what it will look like.
PDF is the history of the Moth. There were a number of versions round the world as it went along,- scow, international moth (dinghy type) and todays high speed foiling moth.
Lots more to do yet

1/16th Model Slipway Trent deck splitting
The deck is splitting and cracking on the surface and join to the hull. What glue is recommended to prevent further cracking and fill the cracks?
Thanks

A Banana Boat??!
Happy Groundhog Day fellow model boaters. Seemed like a good day to start a build blog after the weather we have been having here in SE Texas. From hurricanes to snow fall, now nice sunny temps in the 70's.
I asked my grandson earlier this summer what boat would he want me to build next. Without hesitation, he said a cargo ship showing me a picture of a Maresk Lines container ship in a children's picture book. I thought about this one for several weeks wondering how to build a realistic replica of something that large. My dry dock isn't very big, and the Admiral frowns on large models. One morning at breakfast I was peeling my banana, and I realize the perfect boat. A quick google search verified my thinking of the perfect cargo ship.
I have lived in this area all my life, and my first job was in the small gulf port town of Freeport, Texas. In the early 80's it basically only served the shrimp boat operators and commercial fishermen as well as a few cargo ships for Dow Chemical and the like. The size does not compare to the Port of Houston or even Galveston. However, in the 90's the Dole Fruit Company started operations delivering containers of tropical fruit for distribution to the US.
At that time I was commuting to Houston for work, and would see the Dole container trucks on the road and would chuckle to myself "must be a banana boat in port!
The Dole company just celebrated 30 years of service in Freeport, and in 2023 launched two sister container ships, the Aztec and Maya, specifically for the Gulf of Mexico deliveries. These are smaller ships which I estimate carry only about 500 containers.
Since I could not find any plans on the internet for a smaller container ship, I decided to make my own. From pictures of the Aztec, I free handed a graph paper drawing of what I intended to build, and when satisfied, I produced a CAD version in Autosketch.
The attached pictures are of the Aztec in port at Gulfport MS.. The Maya being built in drydock. My hand drawn rendering on graph paper, and a .PDF of the cad version with bulkhead detail.
The model ship will be about 26.5 inches long with a width of about 4.5". I plan to have a brushless motor driving a 1 inch 5 bladed brass prop.

Dumas Pay n' Pak
Hey gang! As you may already know I have the Bluebird K-7 on the shelf for final detailing, the C-2 cargo ship Matson "Pacific Trader" awaiting rigging, and 22 inches of snow on the ground. So I wanted a challenge and grabbed an ancient Dumas Pay n' Pak Hydroplane kit to keep myself from going nuts. This may or may have not been a mistake!
And...you may already know that I've already labeled this build as my "3 day running knife fight" as a boat made of 100% warped plywood is not a walk in the park. Here are some pix starting from frame up to a primer. And yes, to fight this beauty from becoming a warped "banana boat" those are bricks and carpenter's clamps helping me keep her straight! The The bottom is glassed and the rest resin covered. The primer is meant to assist in showing all my mistakes and assist in final sanding prior to a finish coat.
Tough build, but it does look like something out of "Star Wars!"
More to follow.

Thames Barge - Veronica
This is a well know model. I think there used to be an active group of TB modellers, this seems to have been maintained through a Facebook page - However, I don't use FB ! But Sarik models have put the original DVD on YouTube, which does help.

Any experience or advice about making this model - always welcome and appreicated.

Something a little different-Horizon Harbor Tug
Hi yโall. I turned 65 last month, and in preparation for celebrating making it this far without getting myself seriously injured or spending time in jail I sold a few boats and cashed out some excess pto so I could do something I normally donโt doโฆspend more than usual for my birthday.
So, I had a budget, and my goal was to use as much as possible from my savings from boat sales without disturbing the family Kitty much if at all. I was successful, came in under budget, my wife got me two kits and I picked up this-the Horizon Harbor Tug.
Now, Iโm not usually a RTR or RTF kind of person. The few times Iโve purchased a hobby grade ready to run or fly model Iโm usually disappointed. Butโฆthis boat has been praised by modelers of all stripes, and Horizon has kept it in production for 4 years, which I think is some sort of record, as usually Horizons scale offerings last maybe a year, 2 years tops. Also, we have 2 members who are dedicated builders of tugs and submarines that love them to death. So here goesโฆ
I was not allowed to touch my birthday presents until my birthday, so I had time to figure out what I wanted to do with the Harbor. Once I got her on the bench, I gutted her like a fish.
The Harbor Tug comes with a barely hobby grade pistol grip radio capable of 4 channels, a combo brushed esc/receiver, an esc for the fire monitor pump, and a radio controlled electronic on off switch for the led lights. Power is a 700 size motor, this is all supposed to be powered by 3 cells. It does NOT come with the water pump, thatโs 60 dollars more, and from what Iโve seen itโs not as strong as I like.
So, I had to make a mount for my preferred motor, the Zippkits 650 brushless outrunner, thatโs coupled to the shaft with a good solid coupler. Esc is a HobbyWing 16BL30 30 amp unit. I had to do some modifications to mount my preferred Amazon sourced pump, which included drilling out the molded in water pickup and epoxying in a brass pickup, and changing the mounting location of the pump. Pump is powered by a 10 amp brushed aircraft esc-the original that came with the boat works well, but is set up for 3 cells, and doesnโt give me enough voltage at the pump. Originally I was going to use a FrSky 7 channel receiver, but I wanted to try my hand at telemetry. So I used a FrSky X8R so I could run the FrSky FAS40 module, which gives my real Tim battery voltage and current draw. I also added ballast to bring her up to 12 pounds, as the stock weight of 9.5 or so is seriously under ballasted.
Now, the first production runs of this boat had some issues, leaks near the stern and along the bulwarks were common. It seems to me that Horizon did what Joysway did with the DF65, and listened to feedback, as my boat ran dry. There was a bit of water in the hull before the maiden as I was checking ballast and leaks the day before, and there was no appreciable water in the hull after. All systems worked well, and the boat exceeded my expectations.
Now, yโall know me. Youโve seen my build logs. Probably wondering why Iโm loving a boat that I donโt have much time at the bench with. You see, the story doesnโt stop here, oh no, I have more work to do. The real boat this was modeled after is the Taucher O Wulf 8. Horizon put just enough detail to please the average boat modeler, and decaled it with an H on the funnel. My goal is to get her recognizable as the Taucher. I have to do some detail work, add some things thatโs missing, do some lettering, etc. The end game is a stand off scale model of the Taucher. So stay tuned, weโre going for a ride!

Trawler
Haven't been working on my deep- sea trawler for a while. I needed to build some railings on the deck, but didn't want to wait and buy them and pay tariffs on them at an American hobby store, so I got some brass rod here at a local hobby store and soldered some up. I also decided to use the lifeboat kits for the ship. Next step: painting railings. Also need to do all the rigging yet.
