Biologist Antonio Carlos Osse took five years to build the Osseanic in Barueri, involved the family in the artisanal project, and launched the 30-foot fast-trawler into the sea in Caraguatatuba
The Osseanic, a 30-foot fast-trawler built by biologist Antonio Carlos Osse in his backyard in Barueri, became a reality after 5 years and 2 months of family work. Reported in 2023, the story combines artisanal construction, technical planning, and the boat’s journey to Caraguatatuba, where it began its life at sea.
Osseanic was born from an old dream connected to the sea
Antonio Carlos Osse’s relationship with boats began in his teenage years, at Saco da Ribeira, in Ubatuba.
There, he watched anchored boats and imagined trips, dives, and landscapes he could explore by sailing.

Workers were excavating the expansion of the VLT in downtown Rio when they found, underground at the construction site, 15 skeletons and a buried 18th-century church linked to the history erased by the city’s major urban reforms.
The dream continued into adulthood and was shared with his wife, who also had an interest in the sea. Over the years, the family undertook other personal projects, such as writing books, planting trees, and raising their daughters Marina and Carolina.
In his 50s, Antonio Carlos decided to turn the old desire into a concrete project. The idea was to have his own boat, but buying a ready-made boat would require a larger immediate investment.
The solution found was to build the boat at home, with his own hands and family involvement.
According to the case information, the family understood that the process would also be part of fulfilling the dream, not just the final result.
Chosen project provided autonomy for medium crossings
The chosen boat was smaller and simpler than the initial dream, but it needed to meet the main goal: to allow navigation with autonomy. For this, Antonio Carlos purchased the design from a naval architect in the United States.
The design envisioned a motorized boat, with semi-planing capability and autonomy for medium crossings. The estimated range provided in the material was up to 500 miles at cruising speed.
Construction began on March 20, 2017. The method adopted was wood with epoxy, a choice that leveraged Antonio Carlos’s previous experience with machinery, wood, resins, and lamination.
He had already been working for over 25 years in the manufacturing of Canadian canoes. Even so, the Osseanic represented a greater challenge, as it was a cabin boat, motorized, and equipped with hydraulic, electrical, and electronic systems.
To make the project feasible, the family set up a temporary metal structure on their own land, measuring 8 by 11 meters. The space functioned as a shed and avoided rental costs during the years of construction.
Construction took five years and involved the whole family
The work progressed on weekends, days off, and periods of intense dedication. In the first three years, family participation was stronger, according to Antonio Carlos’s account.
In the last two years, the routine began to mix passion and obligation. During this period, the daughters were entering adolescence, which also changed the family dynamics during the final phase of the project.
The Osseanic was declared finished on May 15, 2022. In total, it took five years and two months of construction from the start of assembly in March 2017.
Antonio Carlos stated that the boat was made 100% by the family. The family labor was not included in the cost spreadsheet, which reinforces the artisanal nature of the construction.
Among the technical solutions, he mentioned the self-manufacturing of fuel, potable water, wastewater, and sewage containment tanks. These components were molded on-site with fiberglass and vinyl ester resin.
Building in the backyard required not only manual skill but also organization. Cables, sensors, instruments, and accessories were prepared even during assembly, before the final installation of the engine.
From Barueri to Caraguatatuba, the boat came to life on the coast
With the hull ready in the Barueri warehouse, the next step was to take the boat to the coast. The transport to Caraguatatuba covered about 300 km.
The city was chosen for the installation of the Volvo Penta D4 270 hp engine at an authorized dealer. According to the material, this was done to preserve the equipment’s warranty.
The previous preparation helped in this phase. As part of the systems was already ready, the final assembly of the engine and associated components was facilitated.
After that, the Osseanic went through licensing with the Harbor Master’s Office. With the issuance of the registration, the vessel could finally be placed in the water.
In the first test, the boat sailed with full tanks and eight people on board. In this condition, it reached 27 knots, according to Antonio Carlos’s report.
He stated that nothing broke, came loose, leaked, or burned during the test. The result marked the transition from a handmade project, made in the backyard, to an operational vessel.
Months after the christening, the family was already doing training outings. The new goal mentioned in the material was to take the Osseanic to Alaska, expanding the symbolic reach of the dream that began in Ubatuba and took shape in Barueri.
