At Bering Yachts, our many ocean-going trawlers are built with steel hulls. When it comes to the hull of a large, explorer type yacht, steel boat hulls are a considerably better choice than aluminum. There are a number of reasons, but primarily, aluminum is not built to withstand long, transoceanic trips. On the other hand, steel is incredibly durable and does not require any special treatment in order for it to be ready to go thousands of miles during a single trip. While aluminum has its benefits, the choice is clear when choosing a luxury trawler – steel boat hulls are the superior choice.
While aluminum is an excellent choice for much of the rest of boat construction, it doesn’t make the best material when used as ahull. There are several disadvantages of using aluminum as a boat hull during the construction of a superyacht. To begin with, aluminum is considerably more expensive than steel. Aluminum is approximately $1500 a tonne, while steel is just $50 a tonne. For those looking for the most high-end yacht that money can buy, aluminum might seem like the smarter choice simply because it’s more expensive. This is not the case. There are many benefits that aluminum can not provide compared to steel hull yachts.
Aluminum boat hulls require special corrosion protection to stop corrosion. Aluminum hulls require special bottom paint, as copper in most antifouling bottom paints will corrode the yacht alone. This also plays into the fact that aluminum is not built to withstand long, global trips without being corroded.
For a luxury, multi-million dollar trawler, comfort is critical. Steel hull yachts provide much greater comfort in comparison to aluminum hulls, which can often result in a noisy and uncomfortable ride. The lack of comfort that comes along with aluminum hulls is the result of the lightweight nature of aluminum. It’s for this reason that many yacht owners prefer the added weight and integrity that only steel-hulled vessels can provide.
In comparison to aluminum boat hulls, steel hulls have much better abrasion resistance. Abrasion resistance is the ability of a material to withstand issues such as rubbing, scraping, or erosion that tends to remove material from its surface over time. Having high abrasion resistance allows the steel, and in turn, the boat hull, to maintain its original appearance and structure.
Furthermore, steel is used in many more applications than boat construction, making the material easier to find. Owners of boats with an aluminum hull might find it challenging to find the repairs that the boat requires. Steel hull boat owners don’t have to worry about that, as most shipyards will have the material necessary to repair the boat (if any damages occur, which is unlikely) at the ready.
