I lived in Brazil for 26 years. Kalmar is a respected yard founded by a Swedish fellow (now dead - the daughter, Lorena Kreuger, carries on). They specialise in high end wooden (cold molded) craft, built to order.

The 70-foot fiber-hull trawler refit project is a complete example of Kalmar Shipyard's one-off custom vessel construction service. The artisanal and exclusive work of Estaleiro Kalmar is not just restricted to color options, finishes and modular interiors. Kalmar has expanded its range of operations, offering a complete service, building 100% customized vessels, understanding and fulfilling all customer requirements and preferences. Kalmar added project management and management of partner teams hired for outsourced services to the construction process, those not included in the scope of carpentry and painting. Systems and equipment are specified and assembled according to the customer's choice.
In projects like this, where the entire interior has been remodeled, it is necessary to hire an architect to develop design and decoration solutions, which follow the client's demands, and which also take into account any construction restrictions that may exist. The customer can choose how they want their internal layout, what type of design and finish they prefer in the furniture (straighter lines, more curves, friezes, etc.), the type of wood tone and other materials they would like to add to the furniture (synthetic straws, stones, mirrors, Corian, etc.), preferred colors, types of hardware (handles, doorknobs, sliding system, etc.), floor finish, appliances, lighting system and types of luminaires, among other details.
In the refit of the Zion trawler, an old boat was renovated, there was a need for hull maintenance work, before starting the fine carpentry and finishing work. This work, also carried out by Kalmar Shipyard, is very important for the durability of the vessel.
