Some packaged marine generators, say 15HP/10kW, are very quiet with full sound enclosures. As far as stability issues go, I would think there are...
A moderate monohull, say 48 x 10 ft, will get you 6 knots easily with less than one horsepower per ton of displacement. Proper choice here...
I was involved with concrete boats as a senior mechanical engineering thesis, way back in 1969. We designed and tested to destruction several...
Your units stated are incorrect, you should get this type of thing properly sorted, and understand the engineering concepts before proceeding....
Inside system fouling can be low, provided the sealed system is protected from corrosion, and kept clean. Sea water side fouling can be covering...
From an engineer that has spent over 50 years as a heat transfer specialist: For this condition, a heat exchanger has resistance to heat flow...
"I was thinking, if they didn't sink, such as supported by some sort of flotation, pontoons, would the drive tracks be able to bring them up to...
The fast snowmobiles get going on the solid, (or very shallow water, a few inches deep) then enter the deep water. They sink like a rock if they...
The better efficiency for displacement boat speeds is fundamentally obtained by moving a large amount of water. Pumped propulsion in 1790 was...
"...One concept had the engine and a lot of linkages hooked up to oars. Not real practical. The other one that is probably the easiest most...
I have been running a sidewheel steamer for more than a decade, and have a couple other steamboats as well as IC boats. See youtube video: <<<...
Is it really feasible to reduce the draft on a vessel of such dimensions by 3' and maintain a good seaworthy vessel? ANS: Yes, it is technically...
I worked for the USACE years ago, and we specified a 34 ft (10 M) crewboat capable of operation in ice up to 2 inches (5 cm) thick. As I recall...
One distinction that has not been defined is that the request is for "Engineering Drawings", whereas the technical issue is really to get the...
Some real numbers, approximate but with accuracy OK for your original question. This data is fundamental, and works for all size hulls. Solar...
"No free lunch just with the throttle." Is that so? According to my training there is a huge saving in fuel with just the throttle. For...
I consider myself a fairly active retired person, launching my boats frequently from trailers, repairing roof parts on our 1693 house, etc....
Cruising with 4 adults - Electric Javelin
I built a small all electric cruiser years ago, and believe your goals are easily met. I converted a 14 foot O'Day Javelin sailboat hull, a...
I have used common tubing compression fittings, with an O-ring inserted instead of the metal furrel to seal the shafts of a few large model boats....
