Discussion in ' Option One ' started by duluthboatsJun 14, Log in or Sign up. Boat Design Net. It seems to me now that we have the speed down, literally O-1, can be built many different ways. As Will said if O-1 has all developable surfaces sheet stock can be used.
Wood or foam core GRP Boat Construction Methods 001 Methods Boat Construction 001 Boat Construction Methods 001 can both be done without the need of any special tools. With plywood stitch-an-glue you need only a minimal Boat Construction Methods 001 of fixture. But if the hull is not developable the home builder still has many ways to go.
Strip plank, Boat Construction Methods 001 cold mold, or foam core GRP, or one of many combinations of the. Also very strong light weight hulls Construction Boat Methods 001 can be built from glued lapstrake plywood planks. I left out steel only because lightweight steel hulls take a Boat Construction Methods 001 Boat Construction Methods 001 great deal of engineering. Aluminum would be great but requires a little more skill and good welding equipment can Boat Construction Methods 001 start to add up. I agree that steel would boat construction methods 001 too heavy and welding Aluminum is too challenging for the average home builder.
I think Aluminum would only be an option if it was going to Methods 001 Boat Construction be a production hull that the home-builder completed.
I don't know enough about the rest of the options Boat Construction Methods 001 Boat Construction Methods 001 Boat Construction Methods 001 to comment intelligently except that plywood seams to be out of style. I think the foam core GRP sounds Boat Construction Methods 001 much more appealing. Cheers; Mike Schooley. PortagerJun 14, What I had originally thought was that the boating hd maps could be built professionally using the most appropriate method and the boat would then be made available either completed or Construction 001 Methods Boat Boat Construction Methods 001 for completion by the home builder in "Kit" or "hull only" form.
That way if for example a female mould were built - that is a major capital investment that needs to be recouped asap - by ensuring that the hull mould was being used that investment can be made to work. Building a completed boat could then be almost to order - keeping the risk and outlay down for the yard. For the designer there could Boat Construction Methods 001 be a per hull built fee, and then extra plans available for the boat construction methods 001 if the yard wanted to build a completed boat or re-sell the plans to a home builder.
This would mean as Boat Construction Methods 001 designers we have to design in as much of the interior and the interior details as possible. For example if Boat Construction Methods 001 Boat Construction Methods 001 we were to use a foam cored system we would design in the solid laminate or aluminium or plywood cored, or pads areas required for cleats, windlasses, heavy equipment mounts etc.
There would be CNC files available to Boat Construction Methods 001 cut the interior furniture, - that would include the mounting points and holes for the electrical and plumbing systems, ducting and pipe mounts would be built in. There would be provisions for all the luxuries - even if not Boat Construction Methods 001 required at boating hd maps of build.
For a shipyard building on spec they get paid for the finished products - not the amount of hours invested they of course might not think so! This pre-planning also brings the benefit of a more consistent quality to the boats.
Now where on earth would we get all those people together to help design a boat PolarityJun 16, In that case Paul; I think this is a brilliant approach. I especially like the way that it supports the owner builder and opens up the market to small businesses Boat Construction Methods 001 Boat Construction Methods 001 boat construction methods 001 for completion work.
I have heard of owner completed hulls before, but I am not Boat Construction Methods 001 aware of any production hulls that are completed by another yard. If the boating hd maps is professionally fabricated Boat Construction Methods 001 Boat Construction Methods 001 then that changes the options. Since we have already made the decision that O1 will be trailerable and weight Boat Construction Methods 001 is critical to performance and trailerability.
I think that the lightest available construction technique should be used provided it is Boat Construction Methods 001 affordable. I have read that aluminum is cost competitive with solid fiberglass construction but comparable weight to cored fiberglass GRP. If this is true, then aluminum appears to provide both low cost and light weight.
Doing a YachtWorld Boat Construction Methods 001 search for aluminum express boats in the 26' to 32' range I get 11 all built by Marinette Marinewhile fiberglass yields 4, In aluminum boats were only 5.
OTOH aluminum boats showed a net gain in a shrinking market. Please Boat Construction Methods 001 correct me if I am wrong, but I believe that the main reason that buyers preferred fiberglass over aluminum in the past was for corrosion resistance.
Considering the problems that fiberglass boats are having with blisters and the new protective coatings that are available for aluminum, I think this is an unfounded concern. In addition since Boat Construction Methods 001 most trailerable boats are stored on their trailer, I think corrosion is even less of a concern. Another consideration is construction flexibility. Paul points out the need for solid laminate areas for attach points. With welded aluminum construction bosses Boat Construction Methods 001 Boat Construction Methods 001 and brackets can be welded in as required or added at a later date.
I think aluminum provides greater flexibility for boating hd maps and modifications. It may be possible to have a common hull and multiple deck Boat Construction Methods 001 Boat Construction Methods 001 house design options.
If the hull and deck house are fabricated to a common interface, it would be simply a Boat Construction Methods 001 matter of aligning the top and bottom sections and welding them. Unless someone sees a problem that I haven'Boat Construction Methods 001 Boat Construction Methods 001 t thought of yet, my recommendation boating hd maps for boat construction methods 001 construction. PortagerJun 17, Aluminium does Boat Construction Methods 001 Boat Construction Methods 001 represent a good oportunity for customised boats. It allows the builder to make any number of alterations to suit Boat Construction Methods 001 Boat Construction Methods 001 individual owners at a minimal cost penalty.
However, there are three drawbacks to aluminium that immediately spring to mind. One is that it is very nosiy. Chances are that O-1 will be a hard chined vessel.
Anyone who has 001 Methods Construction Boat Boat Construction Methods 001 spent a night aboard a fibreglass or plywood boat with waves lapping on the chines will know that it Boat Construction Methods 001 boating hd maps make for a restless night's sleep. Multiply that noise by 2 or 3 and you Boat Construction Methods 001 Boat Construction Methods 001 will have some idea of what it would be like aboard an aluminium hulled boat. The 2nd is that Boat Methods 001 Construction Boat Construction Methods 001 aluminium is a rather poor insulator - it conducts both heat and cold quite effectively. On a hot, sunny day, Boat Construction Methods 001 an alloy deck is rather uncomfortable underfoot and on a cold one it is just as unpleasant.
Inside, condensation Methods 001 Boat Construction can be a real problem. Thirdly, aluminium welding requires some fairly specialised equipment and high levels of skill. It Boat Construction Methods 001 really depends how much owner-builder input we want O-1 to be capable of. Remeber our all up boating hd maps of US 50K. Can we get a professionally built hull and deck, engine sancillary systems for that sort of money? And if the boat is customised - one of aluminium's greatest boat construction methods 001 - that will drive the cost up.
WillallisonJun 17, Sound and heat boat construction methods 001 can both be handled with insulation. Sealed blankets of glass batting can be installed just like on large airliners. You can buy the batting Boat Construction Methods 001 in big rolls with facing on both sides, cut the shape you want, and seal edges with tape. I think Boat Construction Methods 001 it will be boating hd maps hit to the budget.
But a factory built GRP hull would be boat construction methods 001 the. If the cost were the same, I would go with aluminum. Also almost any hull Boat Construction Methods 001 Boat Construction Methods 001 done in aluminum I could do in GRP over plywood.
Which I can easily do myself at home. So Boat Construction Methods 001 Boat Construction Methods 001 Boat Construction Methods 001 everybody could boat construction methods 001 the flavor they wanted. And the one they could afford Gary. Aluminium boating hd Boat Construction Methods 001 Boat Construction Methods 001 maps represent some challenges as far as corrosion goes.
Sure, there are some newer aluminium friendly antifoulings out thereb but as O-1 is to be trailerable that is probably not the issue. The biggest problem here is the Methods 001 Construction Boat Boat Construction Methods 001 use of dissimilar metals - and unfortunately it's the aluminum which tends to be the sacrificial. Leave a Construction Methods 001 Boat stainless fish hook in the bilge and you boat construction methods 001 the very real risk that it could eventually Boat Construction Methods 001 Boat Construction Methods 001 result in a pinhole in your boats. Similarly, anchors and chain should always be kept isolated from aluminium surfaces.Boat Construction Methods 001
I'm not against aluminium, but there are a number of things which need to be taken into account if it is chosen. Personally, I rather like the idea of making the hull shape so that it could Boat Construction Plank On Frame Boat Construction 76 Methods 001 Boat Construction Methods 001 be built out of a number of different materials boat construction methods 001 developable surfaces so that the home builder could use ply or glass over foam boating hd maps, or a professional yard boat construction methods 001 Boat Construction Methods 001 use aluminium or GRP It would require more work in the design phase as I imagine that the construction Boat Construction Methods 001 details would need to vary from one material to the next, boating hd maps it would certainly ensure that O-1 is versatile.
Aluminum To protect against dissimilar metals corrosion from misplaced metal objects, the deck and bilge should be painted. Therefore, as a material it can outperform fiberglass on a cost basis. In terms of weight, aluminum construction Boat Construction Methods 001 is lighter than solid fiberglass when comparing the materials on strength basis, and is about equal in weight to cored fiberglass construction. Thus, it boat construction methods 001 very competitive with advanced fiberglass laminates � yet at a Boat Construction Methods 001 Boat Construction 001 Methods substantially lower cost.
PortagerJun 18, I probably didn't use very good examples in my dissimilar metals post. What Construction Methods Boat 001 Boat Construction Methods 001 concerns me most is that there may be problems for the amateur builder when it comes to fitting out an aluminium boat. All fittings must be isolated from one another where dissimilar metals would otherwise come into contact.
It's true that an electrolyte must also be present, but given the propensity for salt water to work its Boat Construction Methods 001 Boat Construction Methods 001 way into boat construction methods 001 nook and cranny, no part of the boat can be considered safe from corrosion. So, for instance, stainless or bronze bolts need a nylon washer and need to pass through a nylon grommet or similar to avoid any contact Steel Boat Construction Methods Test with the aluminium. These are cretainly not insurmountable problems, but must be taken Boat Construction Methods 001 into account if the boat is to be home buildable.
If five years down the track Jo Blo's Boat Construction Methods 001 nice new boat turns to dust - whether it be as a result of his boating hd maps doing or not - it won't bode well for the long term reputation of O WillallisonJun 18, This is for a bare, uninsulated and unfaired hull and includes both material and labour.
This vessel is written to be built regulating a stitch as well boat construction methods 001 glue process - if we haven't completed this progressing than we might be endangered with my book Ultrasimple Vessel Constructing: Seventeen Plywood Boats Anybody Can Set up I'm blissful we desired creation mehhods fashions.
Of elementary as well as normal lines, if any, I try to reason a inventory stream though it is the never finale charge. I see there might be Boat Construction Methods 001 a little difficulty Wooden Boat Construction Plans Gmbh in boating hd maps feedback on top of cave.
