Sobre este barco
Greetings to all naval modelers.
In this section of the site (I hope I got it right this time) I want to include a 1:50 scale model that I invented many years ago.
It is not taken from kits or existing projects.
It was born as a toy to entertain my son but little by little I added slightly more accurate modeling elements.
I designed the hull but without using software, I drew it with pencil and paper. However, if you are not capable of designing a hull, the software is of little use.
It's not beautiful (let's even say a little ugly), I know this, because it wasn't born with a homogeneous project but is the result of ideas that came along little by little.
I'm fond of it and "every cockroach is beautiful for its mother" ahahahahahah.
However, it was very useful for me to do nautical tests and learn the rudiments of electronics on board RC models.
The motor is a 24 volt brushed motor but is normally powered by 6 volts. However, there is the possibility of bringing it up to 12, 18 and 24 volts. Up to 12 volts has been tested, above no.
It has no protruding fins or keels and can navigate in about 10cm of water.
Her name is FRANCESCA but I gave her to my son.
I will not include all the assembly phases but only some summary photos, so as not to bore you with an already finished model.
Of course, if anyone asks I will be available for any details.
I will only post four or five more messages related to the most interesting sailings, with very short descriptions of the places.
Length on deck: 80 cm
length on the waterline when empty: 78 cm
length on the waterline at full load: 80 cm
overall length: 112 cm
maximum width: 21.2 cm
full load draft

empty draft

tree height: 41.5 cm
height from keel to deck: 17.5 cm
total height: 59 cm
weight without batteries: 5.42 kg
weight with three batteries
lead acid VRLA AGM, 6V 4Ah: 6.27 kg
motto: LEPANTO 1571

This is the latest video of the schooner brig Francesca.
It is not the last in chronological order, rather one of the first.
In fact, she still didn't have any measures to waterproof the deck.
Navigation is in the very small lake of Villa Ada, one of Rome's public parks.
The peculiarity of this video is that I put a camera on board to take some shots from the ship itself.
The camera was not a micro camera but a small regular camera. It was very heavy and when the ship took a crosswind this additional weight on the deck caused the whole vessel to list too much.
After sailing for a while (and in the meantime I took on water without knowing it) with this camera I realized that the ship was behaving strangely and the freeboard had decreased a lot.
When I finished sailing and put it back on dry land, I found that there was about a liter of water in the hold.
Luckily it didn't damage any electrical components.
At that time I had a different construction philosophy (which I have totally changed).
Electrical components all at the top (also the motor is protected inside a plastic box).
In fact, initially I had studied a transmission system that absolutely did not prevent water from entering the pipe itself.
It worked but I changed it anyway because there were too many disadvantages including excessive noise.

Today is a good Sunday even if a little cold but the temperatures are right for January.
What wasn't normal was the 21 degrees Celsius of the previous days.
Have a great Sunday yourself 😊
This is the third video montage made many years ago.
Navigation is at Lake Paterno.
I hope you enjoy the images.
LAKE PATERNO
Lake Paterno or Cotilia is a lake in the province of Rieti, in Lazio, located in the San Vittorino plain. Very well known in ancient times, it was a sacred place for many Italic peoples, so much so that Varro called it "the navel of Italy".
Lake Paterno is a basin of karst origin, originating from a sinkhole of the ground (sinkhole, of which it represents one of the most exemplary cases). It has an oval shape and small dimensions (150x190 metres, diameter of 204 metres), but is very deep (almost 54 metres).
It is fed by an underground water source; the water drains through cracks in the limestone rock. The temperature at the bottom is 6 °C, almost constant throughout the year; the one on the surface is usually warmer depending on the season.
It is located at 600 m above sea level. upstream from the lake and about 5 km from the town of Ponte Alto.
The lake is suitable for bathing, fishing and scuba diving.
The remains of a majestic villa dating back to the 1st century dominate the body of water. B.C. probably to be identified with that of the Flavian emperors (so-called Villa di Tito); a short distance away are the remains of the Aquae Cutiliae thermal plant.
surface area = 0.03 km²
length: 190 m
width: 150 m
depth: 54 m

This is the second navigation video.
I hope you enjoy the selected sequences in his time.
This time too I tried to cut out and assemble only the parts of navigation that were not too fast, but I leave the last word to you.
The navigation was done in a city lake inside a public park in Rome.
It is very busy and there is not the relaxed and comfortable atmosphere of a private association pond.
Here in Italy, the lakes of private associations dedicated to modeling are more unique than rare.
I saw that in England there are many clubs of this kind; certainly an enviable situation.
There are many advantages because you can stay safe from theft and damage and in the event of a breakdown you can count on many people.
The Italian naval modeling associations, as far as I know, hold rallies, events and even competitions but often do so in public lakes.
There isn't much to say about the Tor di Quinto lake, it will be one or two meters deep at most, it is 190 meters long at most.
The only advantage is that, being in the city, you don't have to travel far to reach it.
