Big freighters have a bow bulge that seems to be popular if not mandatory. So it is maybe allowable on small boats. A kayaker should know...
Yes, thanks for the warning. My conception could be a likely candidate for such failure. A good reason to not play designer on the internet....
Shaft builders seem to make the design desired. The design I believe is a parametric solution. Meaning two variables must be designed. So in...
ok I won't make shafts for misdesigned conceptions.
I am working on a small 14 foot plywood tug design. The question becomes how to power the tug? In general I have a mandate to have a small...
when I get the prototype done I will report hull speeds using a 4.5 hp Johnson outboard. It will be a basic temporary low strength prototype....
I got to thinking about clarity of communication. There is a likely confounding of sizes of the bilge panels. So to get exact fitting a fitting...
screwed up thinking wise, edge c is cut to a right angle with the flat plane. NOt perpendicular.
Here is a better diagram of the bilge part of my tug boats. It can also be added to contemporary flat bottom tug boats for use as a inboard...
Doug's Tug Inner Hull My fios stinks I will follow up. this posting
My concept is a simple one. There was aa clear statement defining class of chine mating. I never claimed novelty. In my version a dingy must be...
It is kind of hard to explain, but it is like taking a normal mold and forming a plank only mold from its surface. Any direction replicating. So...
I agree it is not to be professionally recommended. If somebody actually made a proper mold for a pure fiberglass chine it would look good enough...
it is just concept. The copper nails would really add strength. Except nails are for planking not plywood. Bolts are not necessarily an invalid...
yeah. I will "can" the whole idea. there is also intergrain corrosion in aluminum. Reynolds is not necessarily honest with the actual rate....
thanks for the replies. I will go back to the study concept stage. Corrosion is a problem! maybe there is some kind of fault tolerant design to...
I like the idea of trying a metal boat build. But cost is an issue. My question is about welding stainless to carbon steel. The goal is to use...
Yes it is rather experimental in intention. It is basically targeted to no chine seams. I see designs without them. You are right the nails...
http://douglaseagleson.blogspot.com I saw the woodenboat show testing self righting of a P.Bolger boat. It is a design from the old days....
on my blogspot I mentioned the concept of the required number of blades. It is obvious that for cost efficiency the number of blades is to be...
