Price is good? It seems insane. You could get a catamaran with more space speed and comfort and the ability to dry out for that price. I...
Pb, Doesn't the Philippines have light wind much of the time though? That's an innovative use for those insulation blocks. What is the working...
Nice job. I think the only real way to quantify that is if you raced in a fleet of one design Nirvanas, then again after the mods to see how you...
So they are travelling at around half hull speed. Even on most cruising yachts going, slower than that wont save fuel. But the engines on...
Check out RM yachts.
Powering requirements seem to be roughly based on displacement. But of course this also changes with scaling too. I am struggling to find...
Need to pay for materials for the big sailing cat eh? Good luck with the sale.
The question was regarding scaling. You agree the issue is not enough power. My arguments relate to the power issue and how it is affected by...
You seem to agree the ships will be grossly under powered. My post demonstrates that the underpowering is worse with the large ship as per the...
How are you calculating the speeds under solar power? Both of those ships will be grossly under powered with the available panel area and would...
The scale factor for panel area VS displacement has been mentioned ad nauseam with links and explanations. The original question has been answered.
:P This is why I said there is a limit to where sail gets more expensive than diesel. I have heard even on megga pleasure yachts with sail its...
This statement is incorrect for a solar vessel, and has been shown to be so due to scaling laws permitting less surface area per unit of...
A good friend of mine is a mechanical contractor for the AU airforce who works on helicopters. I asked him and he pretty much said no chance of...
Might reduce the costs of the mega yacht shell down to 1M from 2M :P
Another benefit. As Oldsailor said his tri tacked much better with the central fin compared to 2 outboard boards. Moving the CE of the board...
Smaller will work better due to scaling laws. Please read this: https://www.av8n.com/physics/scaling.htm#sec-volume-length You will see...
One large foil is more efficient than 2 smaller ones. This is an aerodynamic fact. Less tip losses. 2 regular daggers have 2 sets of tip loss....
A local sail maker, switch sails, races that design. I even think it was on my school uniform!
Agreed Doug. Like I already said, the idea needs to be incorporated into the whole design. The center mounted outboard and fuel tanks and...
