Aluminum has a natural resistance to corrosion in salt water because it forms a thin layer of aluminum oxide over its surface when exposed to oxygen. This layer prevents further oxidation and corrosion.

@@alubatamerica Thanks for the reply ! *"Aluminum has a natural resistance to corrosion in salt water because it forms a thin layer of aluminum oxide over its surface when exposed to oxygen"* I heard that from other sources, but still wondered if additional anodizing were theoretically desirable (but maybe not feasible), creating a thicker and harder layer - it would make for fancy metal dyes, though...

Ease of production?

There are many advantages to flat panel construction. It may be worth your while to watch this video tour with Luc that we posted earlier on Building 100% Aluminum Boats: ruclips.net/video/WI4rc9hxRIM/видео.htmlsi=PsAU6cDFpfUi8nf0

@alubatamerica It is just being lazy/cheap aluminium is easily curved with some effort/machinery . Thid is not what i would expect of a professional alloy hull nuilder

@@alubatamerica have you seen Delos's catamaran build in Australia?

Thanks for your compliment about the design of our hulls, we appreciate it! With the long experience of our shipyard in aluminum boats, and even longer experience of our architects, we actually decided on not using fully cylindrical surface development. Instead, we use the properties of aluminum to our advantage, in order to have an additional slight curve in the opposite direction of the main curve. This creates a slight tension in the hull, and thus a more elastic and resistant hull, which is strongly desirable in blue water cruising ships like ours. That also means we use a mix of off-the-shelf aluminum profiles (where possible because of the curves of the ship) and profiles we assemble in our shipyard (cut outs from the same 5083 aluminum sheets as the skin of the hull), to perfectly shape every curve of the hull, as the resulting transverse sections aren’t exactly straight. We actually don’t use 6061T6 for any of the profiles in the shipyard (although it’s the alloy of choice in aerospace), but we prefer stronger aluminum alloys. Although, ultimately, it doesn’t really have any meaning in the strength of the resulting boat; the ISO standards we hold ourselves to take into account both the alloy used and the welding process in structural calculations. Meaning every boat should be able to handle the same pressures, whichever aluminum alloy she is made of. Of course, with a weaker alloy, it will mean a denser structure than with a stronger alloy, but the resulting hulls will withstand the same conditions. We understand the bow round can be seen as ugly by some, but it can’t exactly be called a compromise; we decided to try it on the first Ovni 400 of the new Ovni range, and carried it on for every new Ovni design since then, as this voluminous (and actually conical) shape offers very comfortable sea-keeping abilities to our sailboats; at least according to everyone sailing on board. But to each their own, there's no accounting for taste! Luc Jurien

Träume können wahr werden 😅🎉

Eventually you'll wake up and then reality hits.

Alubat has launched 3 or 4 hybrids to date. As for the Orcas - we know of 4 Orca encounters with an Alubat and 0 rudder damage!

@@alubatamericagood to know!

Longevity could be the best feature of a well constructed aluminum vessel. The durability of these hulls is such that the boatyard runs a secondary business refurbishing older Alubats (20 years+) with new interiors and technology . The alternative of an FRP boat is far more problematic over the long term. Resale value is also strong and easy to verify by shopping the market.

Absolutely.
