Aluminium sailboat
Sailboat hulls should be both strong and rigid. A fairly obvious requirement you may think, but it isn't always the case, particularly with lightly built GRP hulls. Out of the water, a boat should be capable of taking all of its weight on its keel without undue hull distortion. Afloat, hardening-up both the forestay and backstay should create only minimum distortion. Metal hulls - steel or aluminium - will flex the least and are strongest in terms of impact resistance. Let's take a look at the options GRP (fiberglass) Hulls. Of the four basic materials - GRP, metal, wood and ferro. Aluminum sail boats in Europe have been sitting around in marinas for many years and European marinas on the most part are pretty shabby and poorly built. Electrical leakage can happen at marinas but aluminum sailboats built properly with hulls at 10 mm, built out of aluminum and with proper zinks will be just fine. We have taken our Boreal and put her on the hard in Panama as a precaution to marina problems but we were leaving her there for 6 months unattended. Aluminum sailboats. 17 companies | 48 products.

There's a lot of legend surrounding aluminum sailboats. But not all of it is true. So what are the pros and cons of an aluminum hull? Let's find out. What are the pros and cons of an aluminum sailboat? Aluminum sailboats need a lot of maintenance; especially when they are located in saltwater.

They need to be painted quite often every years. They are expensive upfront. However, aluminum is a very strong and lightweight material. If done right, an aluminum sailboat can last forever, and can be very fast.

A lot of people think aluminum is a bad material for sailboats. But it's not all bad: aluminum also has its upsides. Most of the problems with this material are due to bad build quality.

So the design is bad, not the material. Some say aluminum is the worst material, others say it is the best. In general, sailors who have actual experience with aluminum hulls are very positive, even saying it is exponentially better than fiberglass and steel.

The quality of aluminum used is crucial. If it's not up to par, it will corrode VERY quickly. So you need a reputable boat builder that only uses marine-grade aluminum. Aluminum has a bad rep. That's because there are a lot of cheap, badly-built aluminum boats on the market. Its a shame: aluminum can be the ultimate boat building material. But you need to pay attention to details when building or buying one.

If neglected, aluminum can corrode away quickly. Good strength to weight ratio - Aluminum is very lightweight and very strong. One of the most important factors that determine your speed is the displacement of the hull - aka the weight. A lighter boat is faster. So a well-built aluminum boat is faster, and also stronger than fiberglass. Fiberglass tends to crack when under stress.

In a collision, aluminum will probably just dent. A dent is not that big a deal. A crack is - you will eventually sink. Lighter than all other materials - Aluminum is lighter than steel, wood, and fiberglass.

While steel is as strong as aluminum, it's very, very heavy, so that's not great. Wood is heavy as well, and prone to rot - so aluminum wins. Even the lightweight fiberglass is more heavy than aluminum, while it isn't as strong. Doesn't rust - Aluminum doesn't rust, so, as long as it's above the waterline, you don't need any paint to protect your deck. So while you need to be careful in the bilge, and everything that comes into contact with salt water, the rest will be absolutely fine without much attention.

Small boats are cheaper - Custom aluminum boats are cheap to build because aluminum doesn't require a mold like with fiberglass. The builder simply cuts the sheets to size and welds the hull together. It's an easy and fast material to work with. The material itself is also cheap. But it also means that larger boats are more expensive, because the price of an aluminum sailboat mostly consists of labor costs.

Scratches aren't a big issue - Because aluminum doesn't rust, scratches aren't a big issue. If you scratch your top paint while docking, it will practically heal itself, thanks to oxidation. Lower insurance rate - Insurance companies offer lower rates for aluminum sailboats because they tend to get a lot fewer claims from them. Lifetime hull warranty - Because a well-build aluminum sailboat hull lasts a lifetime, some manufacturers give you a lifetime warranty on it.

Won't crack - If you hit a rock, your hull won't split open like a fiberglass one. You'll just be able to carry on, which can be a game changer.

This also goes for the deck, which means you'll never have leaks -period - if you maintain your boat properly. This is probably the greatest advantage of aluminum over other materials. Small repairs are easy - Small dents and cracks are easily repaired: they can simply be welded. However, welding aluminum is a bit more complicated than steel, and it requires a lot of skill to create strong welds. It's not as easy as fiberglass, which you can simply patch up using epoxy.

Material is easy to modify - You can literally cut aluminum with a regular sheet cutter. It's a very easy material to modify, and as long as you make sure any attachment points are properly treated for corrosion, you can very easily change things around with just regular tools.

It becomes more difficult if you need to weld stuff, then get help from a professional. Especially if it's structural stuff. More complex anti-fouling paint - You will probably have to paint the hull below the waterline more often than you're used to. Also, you need bottom paint without copper oxide. Due to the oxidation of aluminum, any kind of deck paint you apply will form bubbles after a couple of years. Some people don't paint the deck at all, which is perfectly fine.

Electrolysis and galvanic corrosion - Aluminum is prone to electrolysis and galvanic corrosion. Electrolysis is the chemical reaction of metals with saltwater. When metal comes into contact with saltwater, an electrical current runs through the metals: Aluminium Hull Rib For Sale Manchester it turns your boat into a battery, basically.

You need to place anodes on your boat to protect your hull. I'll explain electrolysis in detail below. You need an anode - Sacrificial anodes protect from galvanic corrosion. If you have an aluminum boat that's in saltwater permanently, you definitely need anodes to protect it. A sacrificial anode is basically a piece of metal that's more anode than aluminum, causing it to corrode before the aluminum starts corroding. Fittings are more complex - Due to electrolysis, adding fittings is more complex.

There's really no error margin here. Wherever your alu hull meets another piece of metal, it needs to be thoroughly painted, fitted, and maintained. Otherwise, corrosion will form pretty quickly. A boat without proper isolation between the aluminum and other metals will weather away pretty quickly. Hull repair is expensive - Aluminum is more expensive than steel, and finding a skilled aluminum welder can be difficult. So it can really cost you if you need to repair the hull.

However, a good welder will be quick, which will save you in labor cost. Large boats are more expensive - Since aluminum boats are welded together instead of casted, the labor cost increases exponentially with length. Quality, large aluminum yachts are way more expensive than fiberglass yachts. But they are a lot cheaper in the long run since they are made of a stronger material. Weak welds - Welds on aluminum are prone to contamination.

This simply means that they're more likely to contain gas bubbles. Which of course makes them weak. This isn't a problem for the top aluminum welders. Good boat builders use very skilled welders.

But cheap aluminum boats are hastily put together, and the welds can be a real problem. So make sure to only buy good quality build when you're looking Aluminium Hull Sailboats 80 for aluminum. Lots of low-quality alu boats - There are a lot of low-quality alu boats out there. Especially US build boats have a bad rep. Because aluminum is so cheap to build, lot's of cheap alu boats are being built.

And that means that the overall build quality is lower. So the welds aren't as strong, the hull isn't well-constructed or fitted. If you're buying an aluminum boat, you really need to Aluminium Hull Sailboats 2020 watch out for these budget ones. More noise from water on the hull - Water crashing into aluminum makes a lot more sound than water crashing into fiberglass.

Nothing disastrous, but important to know in advance. Condensation - Old aluminum hulls and steel ones as well suffer from more condensation than fiberglass. However, this is only the case if the boat is not well insulated. Modern aluminum hulls are properly insulated, so condensation shouldn't be a problem.
