Aluminium vs Fibreglass Boats - 7 Points to Consider

Log in or Sign up. Aluminum or Fiberglass? Steve in SoCalSep 6, Not withstanding personal preference and issues like hull noise, can we fibsrglass an insightful discussion on the unique care of each material?

I have read a number of articles regarding aluminum and fiberglass construction, the waters are a bit muddier when it comes to long term issues and maintainability. Lets suppose there are two boats of the same size with the same or similar equipment, both boats are 20 years old and have been well taken care of, both boats have no history of major repair work.

Where are the pitfalls in each material? Do the boats age at the same rate? Are the costs to maintain each boat similar or is one material clearly more costly to maintain? The sizes of the boats are meters. If we move the time frame up to say 5 year old boats; are the issues constant or has technology changed the areas of concern?

This is rather vague intentionally, the reason being I would like to find the strengths and weaknesses in each material in as close to apples to apples comparison as possible. Thanks, Steve. AMGSep 6, Joined: Jul 26, Messages: 5, Location: Sweden. Hi Steve, I think the answer in all four variables you gave, is who built it and how is it maintained. There are good and bad boats yacjts well as owners.

And this is the same fiberglaws you should look at brand new boats. The only real difference is that a painted aluminium boat needs a little more attention to keep blisters away Biggest issue was too much teak trim, paint blisters where the teak joins the aluminum and in yachts aluminum vs fiberglass vessel areas where the welds were not continous.

The paint blisters would take at least 5 yrs to show up. Capt Yachts aluminum vs fiberglass vesselSep 6, I feel the aluminum is much more maintanence. The aluminum vessel needs to be painted more often, every once in a while a plate needs to be changed on the hull due to electrolyses.

If any metal tools are dropped anywhere in the bilge of an aluminum boat especially copper it is a disaster. Also you have to be careful what metals if any are used throughout the boat when it comes to piping and water lines when doing repairs and. Fiberglass you don't have these issues. It Sluminum harder to do a repair on fiberglass if damaged, but not that much more difficult in most cases unless the yadhts is severe.

Loren SchweizerSep 8, Metal boats are generally constructed with tankage integral with their hull bottoms. Especially in the area of blackwater tanks, the fiberglwss can be prone to wasteage on the inside. There is no substitute for an audiogage periodically.

Yachts aluminum vs fiberglass vessel in SoCalSep 8, Good question. I know freshwater tanks in steel boats receive 'job-specific' paint jobs. As regards sailboats changing the dynamics, I don't think oxidation knows if it's going fast or slow. K1W1Sep 8, It would seem like bladders would be desirable in these locations? Merely an observation.

Hi, IMO Bladders are not any use at all for anything yachts aluminum vs fiberglass vessel term, they qluminum not fill easily and tend to suffer failures from chafe in a short period of time, this can be very short of they are installed and filled on anything that sticks up even as slight as weld splatter.

That is quite contrary to my experience with aircraft. Hi, I yachts aluminum vs fiberglass vessel that Bladders are very good in aircraft, Air craft and yachts are two completely different beasts. I am also aware from my limited experience with Helicopters of the ability of aircraft bladders to be self sealing in event of someone shooting holes in one, These type baldders are quite different in construction from what you will find in use on boats which is what I was referring to with yachts aluminum vs fiberglass vessel post above yours, not aircraft ones.

If and I use the term as a possibility; if bladders yachts aluminum vs fiberglass vessel quality were used in integral tanks, would this eliminate the general areas of corrosion concern with an aluminum hull?

I have not said my preference however you can see where this is going, I will say I have a Dynasty tig welder in my garage Yachts aluminum vs fiberglass vessel you rather run into a log or container in a Aluminum boat or a glass boat? At sail boat speeds. AMGSep 8, Kanter Don't know if you need a builder, but Kanter Yachts has quite a bit of experience in building some great aluminum yachts, both power and sail, while working with yachts aluminum vs fiberglass vessel known designers such as Chuck Paine, Ron Holland, Dave Gerr and Greg Marshall.

Others refer to Guinea coast peoples using war canoes of varying sizes � some 70 feet in length, 7�8 feet broad, with sharp pointed ends, rowing benches on the side, and quarter decks or focastles build of reeds.

The watercraft included miscellaneous facilities such as cooking hearths, and storage spaces for the crew's sleeping mats. From the 17th century, some kingdoms added brass or iron cannons to their vessels. The city-state of Lagos for instance, deployed war canoes armed with swivel cannons. With the development of the carrack , the west moved into a new era of ship construction by building the first regular oceangoing vessels.

In a relatively short time, these ships grew to an unprecedented size, complexity and cost. Shipyards became large industrial complexes and the ships built were financed by consortia of investors. These considerations led to the documentation of design and construction practices in what had previously been a secretive trade run by master shipwrights, and ultimately led to the field of naval architecture , where professional designers and draftsmen played an increasingly important role.

The ships of the Napoleonic Wars were still built more or less to the same basic plan as those of the Spanish Armada of two centuries earlier but there had been numerous subtle improvements in ship design and construction throughout this period. For instance, the introduction of tumblehome ; adjustments to the shapes of sails and hulls; the introduction of the wheel; the introduction of hardened copper fastenings below the waterline; the introduction of copper sheathing as a deterrent to shipworm and fouling; etc.

Though still largely based on pre-industrial era materials and designs, ships greatly improved during the early Industrial Revolution period to , as "the risk of being wrecked for Atlantic shipping fell by one third, and of foundering by two thirds, reflecting improvements in seaworthiness and navigation respectively.

One study finds that there were considerable improvements in ship speed from to "we find that average sailing speeds of British ships in moderate to strong winds rose by nearly a third. Driving this steady progress seems to be continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in a given wind.

By contrast, looking at every voyage between the Netherlands and East Indies undertaken by the Dutch East India Company from to , we find that journey time fell only by 10 per cent, with no improvement in the heavy mortality, averaging six per cent per voyage, of those aboard. Initially copying wooden construction traditions with a frame over which the hull was fastened, Isambard Kingdom Brunel 's Great Britain of was the first radical new design, being built entirely of wrought iron.

Despite her success, and the great savings in cost and space provided by the iron hull, compared to a copper sheathed counterpart, there remained problems with fouling due to the adherence of weeds and barnacles. As a result, composite construction remained the dominant approach where fast ships were required, with wooden timbers laid over an iron frame Cutty Sark is a famous example.

Later Great Britain ' s iron hull was sheathed in wood to enable it to carry a copper-based sheathing. Brunel's Great Eastern represented the next great development in shipbuilding. Built in association with John Scott Russell , it used longitudinal stringers for strength, inner and outer hulls, and bulkheads to form multiple watertight compartments.

Steel also supplanted wrought iron when it became readily available in the latter half of the 19th century, providing great savings when compared with iron in cost and weight. Wood continued to be favored for the decks. During World War II , the need for cargo ships was so great that construction time for Liberty ships went from initially eight months or longer, down to weeks or even days.

They employed production line and prefabrication techniques such as those used in shipyards today. The total number of dry-cargo ships built in the United States in a year period just before the war was a grand total of two. During the war, thousands of Liberty ships and Victory ships were built, many of them in shipyards that didn't exist before the war.

And, they were built by a workforce consisting largely of women and other inexperienced workers who had never seen a ship before or even the ocean. After the Second World War, shipbuilding which encompasses the shipyards, the marine equipment manufacturers, and many related service and knowledge providers grew as an important and strategic industry in a number of countries around the world.

This importance stems from:. Historically, the industry has suffered from the absence of global rules [ citation needed ] and a tendency towards state - supported over-investment due to the fact that shipyards offer a wide range of technologies, employ a significant number of workers, and generate income as the shipbuilding market is global. Japan used shipbuilding in the s and s to rebuild its industrial structure; South Korea started to make shipbuilding a strategic industry in the s, and China is now in the process of repeating these models with large state-supported investments in this industry.

Conversely, Croatia is privatising its shipbuilding industry. As a result, the world shipbuilding market suffers from over-capacities, depressed prices although the industry experienced a price increase in the period � due to strong demand for new ships which was in excess of actual cost increases , low profit margins, trade distortions and widespread subsidisation.

All efforts to address the problems in the OECD have so far failed, with the international shipbuilding agreement never entering into force and the � round of negotiations being paused in September after no agreement was possible. After numerous efforts to restart the negotiations these were formally terminated in December Where state subsidies have been removed and domestic industrial policies do not provide support in high labor cost countries, shipbuilding has gone into decline.

The British shipbuilding industry is a prime example of this with its industries suffering badly from the s. In the early s British yards still had the capacity to build all types and sizes of merchant ships but today they have been reduced to a small number specialising in defence contracts, luxury yachts and repair work.

Decline has also occurred in other European countries, although to some extent this has reduced by protective measures and industrial support policies. In the US, the Jones Act which places restrictions on the ships that can be used for moving domestic cargoes has meant that merchant shipbuilding has continued, albeit at a reduced rate, but such protection has failed to penalise shipbuilding inefficiencies.

The consequence of this is that contract prices are far higher than those of any other country building oceangoing ships. Beyond the s, China , South Korea and Japan dominate world shipbuilding by completed gross tonnage. The market share of European ship builders began to decline in the s as they lost work to Japan in the same way Japan most recently lost their work to China and South Korea. Over the four years from , the total number of employees in the European shipbuilding industry declined from , to , Modern shipbuilding makes considerable use of prefabricated sections.

Entire multi-deck segments of the hull or superstructure will be built elsewhere in the yard, transported to the building dock or slipway, then lifted into place. This is known as "block construction". The most modern shipyards pre-install equipment, pipes, electrical cables, and any other components within the blocks, to minimize the effort needed to assemble or install components deep within the hull once it is welded together. Ship design work, also called naval architecture , may be conducted using a ship model basin.

Previously, loftsmen at the mould lofts of shipyards were responsible for taking the dimensions, and details from drawings and plans and translating this information into templates, battens, ordinates, cutting sketches, profiles, margins and other data.

Modern ships, since roughly , have been produced almost exclusively of welded steel. Early welded steel ships used steels with inadequate fracture toughness , which resulted in some ships suffering catastrophic brittle fracture structural cracks see problems of the Liberty ship.

Since roughly , specialized steels such as ABS Steels with good properties for ship construction have been used. Although it is commonly accepted that modern steel has eliminated brittle fracture in ships, some controversy still exists. As modern shipbuilding panels on a panel line become lighter and thinner, the laser hybrid welding technique is utilized.

The laser hybrid blend focuses a higher energy beam on the material to be joined, allowing it to keyhole with a much higher depth to width ratio than comparative traditional welding techniques.

Typically a MIG process trails the keyhole providing filler material for the weld joint. This allows for very high penetration without excessive heat input from decreased weld metal deposited leading to less distortion and welding at higher travel speeds. All ships need repair work at some point in their working lives. A part of these jobs must be carried out under the supervision of the classification society.

A lot of maintenance is carried out while at sea or in port by ship's crew. However, a large number of repair and maintenance works can only be carried out while the ship is out of commercial operation, in a ship repair yard.

Prior to undergoing repairs, a tanker must dock at a deballasting station for completing the tank cleaning operations and pumping ashore its slops dirty cleaning water and hydrocarbon residues.
