aluminum panels Aluminum or Steel Sailboats - Which is Better?

Most sailboats are fiberglass these days.But if you're looking for a strong sailing boatYou may choose steel or aluminum.Fiberglass is a fine for normal use,But if you want to cross the oceanOr give your sailing boat a tough life,metal is best.They are also good material if you want to have your own sailing boat design built.The reason aluminum or steel is the best is that the metal is strong and hard,When it's really hard to hit,they bend -Fiberglass, and even state-of-the-art composites will break,Even crushing.Then the sailing boat will almost certainly sink.Sailing boats with dents on the hull can continue.There are other advantages.too.The glass steel boat usually has a separate keel with bolts in place.Bolt 'work' in the reserved hole of the hull,Then expand a little,You may get a leak in a few years.Worse still,If it's really hard for you to press your sailboat,Bolts can break,You lost the keel.This often happens in racing cars.And cruising sailing boats may occur as well.The keel of a steel or aluminum ship is formed as part of the hull,So it can't fall off-Ballasts of lead or steel are encapsulated insideWhere it can't move.If you're looking for a 20 -?28 feet sailing boats around the river,Small river mouth and sea cruise,Then the fiberglass is good.But if you want to go furtherOr you want your boat to be a specific design,Choose aluminum or steel.Many companies offer excellent designs for metal sailboats,And some offer a set of panels that you weld together-Or welded together -?Usually done with instructions.Twenty years ago.Welding steel is much easier than aluminum,But modern welding devices and alloys,Aluminum can be welded easily with only a little bit of training-Hours, not weeks.Therefore,More and more sailboats-And smaller steamboats-Made of aluminum.But the next question is:Should I choose steel or aluminum?The things to consider are:1.2.3.1.Steel is stronger than aluminum,But this is not the advantage of sailing because if the panels of the hull are too thin,It's hard for them to weld without distortion,You will end up with a wavy plate Hull.The minimum practical thickness is about 1/8 (3 mm)And an aluminum hull made of 3/16 (5 mm)The plate is strong enough for a 35-Foot yacht, lighter than steel boat.If you're building a sailing boat of 40 or 50 feetThe weight savings of aluminum in steel will be considerable-In all cases this allows the designer to take the weight and it is needed for a good sport at Sea-in the keel.As a result,Aluminum sailing ships usually have a sea-kindly motion.There's a rowing boat.Weight loss is an advantage,Although the ship made entirely of carbon fiber is lighter,But fragile.2.On its face,Steel and aluminum should last for a long timeBoth need some attention.Both can suffer current corrosion in brine-Especially in marinas-So you need more sacrificial anode than fiberglass,You need to update them regularly.Aluminum is at a slight disadvantage in this regard-You have to keep a good anode,But it's not a problem because these usually last more than one season.Aluminum plates exposed to the atmosphere automatically form an oxide film,This can prevent further corrosion.As long as the panel is dry,They are not corroded.Therefore,It's best not to paint most of the hull,And will deck non-slip panels -These are like rubber pads that are bonded in position -?Not non-For example, slippery paint.A little concern,The aluminum shell will last for a long time.Steel is very different because it always tries to corrosion or rust.It must be treated,The coating then protects it.It's usually easy to see what's going on outside,And keep the hull in good shape,But it's not hard to see what happened at the bottom of the cabin?And lockers behind and other places.Almost always,A few years later,The steel hull will start to erode the interior,Enter due to condensation or water.Therefore,The steel boat is unlikely to give some trouble for a long time-Unless it has a very thick panel-like a ship,In this case, it will be very heavy.When steel starts to rust badly,It costs a lot of money to repair.I have encountered several steel sailing boats with problems.It took me six months to get to know a couple.Work every day,Remove rust from the hull of their steel sailboatFortunately,The hull is thick and well protected so it keeps the sound.A sailing boat about ten years old was found to rust heavily on the whole hull-Extensive repair requiredNew panel.The ship is worth about $30,000 in good condition,But it costs $20.000 ships came out for welding and were then refitted.The most important thing is that it costs $10 for welding repairs.000.In other words,The ship is almost worthless.Another man I know bought a 32 feet steel sailboat that was only a few years old.On maiden voyage,He found the water in the cabin. he found that the water was leaking from the hull.He returned to the port,Send it safely to a proper yardWhen I first met him, he had already started to fix it.The steel boat cost $75.000,However, the hull is full of rust and can be pushed through a small screwdriver in many places.He told me that rust is mainly along the weld and reinforcements.I met him a year later.He has finished welding the hull.He had to replace almost all the panels under the waterline.Then pack the boat.He got help from his father and friends.But he still thinks he paid $70.000 to repair.On balance,therefore,I suggest you buy an aluminum sailboat instead of a steel one.And resist the temptation to paint the complete hull-There's just a band painted on the top,and of course,Resistance before application of epoxy coated underwater hullfouling.
