    is there a on the Internet for materials for the bottom of the boat, for example, how thick (layers with fiberglass, carbon fiber ..) at what spring should the bottom of the boat be made,
    amount of resin, gelcoat, fiberglass (carbon fiber) per square meter

    There is no such calculator. This is design work which should be done by specialist.

    Especially if you are going to use carbon fiber.

    I found this calculator on the Internet for fiberglass
    Working Out Quantities https://www.cfsnet.co.uk/acatalog/methods_workingoutquantities.html

    as I understand main resin is polyester rezin
    gelcoat is an epoxy paint
    I do not know what is - Tissue, Topcoat.
    "Catalyst/Hardener" this is hardening accelerator for polyester rezin or
    second component for gelcoat

    I'm just trying to calculate the approximate price of a small boat like

    I think the OP needs to explain the context of his asking of these questions. Certainly he appears to have little grounding in the subject, so it would help to know where he is coming from, figuratively speaking. I hope its not as a prospective boat builder.

    All Thermo-Calc installations come with a module called the Material to Material Calculator that lets you look at how materials change from one to another. Compared to diffusion calculations, these computations are far simpler and faster because they are only based on thermodynamic equilibrium. Every installation of Thermo-Calc comes with the Material to Material mwst rechner Calculator.

    At 650 °C, the sample curve illustrates the slow change from martensitic stainless steel on the left to alloy 800 on the right. At this temperature, neither substance is anticipated to generate any harmful phases by itself. However, we observe that the harmful sigma phase may arise in the transition zone of these two materials (red line).

    Although this kind of computation is quick and easy, it ignores non-linear diffusion effects. As a result, the actual phases that are present in a diffusion couple or welding connection of these two materials may differ.

    Common Uses of the Material in Material Calculators
    Any scenario where several materials come into touch with one another and will either react strongly (often at high temperatures) or gradually change into one another by design can be used with the Material to Material Calculator. The calculator avoids the complexity of diffusion calculations by performing equilibrium calculations over linear composition gradients, enabling quick, easy, and stable computations. However, it is unable to consider intricate non-linear or non-steady-state diffusion effects.

    The Material to Material Calculator in Thermo-Calc lets you quickly estimate how materials transform into one another under thermodynamic equilibrium, without performing full diffusion calculations. For example, at 650 °C, a transition from martensitic stainless steel to alloy 800 may produce the harmful sigma phase in the interface zone, even though neither material forms it alone. This tool is useful for scenarios where materials come into contact, like welding or layered components, but it cannot account for non-linear or transient diffusion effects, so actual phases may differ.

    You are asking for the scantlings and laminate schedule for a boat. It can be done from scratch by calculating all the forces, weights, etc. However, for small boats that operate at moderate speeds you can simply follow the same schedule from a similar boat.

    The OP is in the country of Georgia. He may not have a command of English. Yes he needs to explain what he is trying to accomplish but he may not know how to explain it in English.

    I think for a boat like that using a similar one as an example would be fine. However, I don't have a clue of what the regulations are in Georgia, if any.
