Love your coverage of the Silent Yachts and noticed you like to take questions :-)

1) They have the kite setup in the front. Was wondering if they have tested to use the force on the propeller for "regenerative breaking" in the motor and charge the battery packs. If I am not mistaken not all motors can do regenerative breaking though...
2) Besides Silent Yachts. Am endlessly fascinated by foils. And came accross a paper where they tested foils on a catamaran to reduce resistance. The take away is increased resistance at slow speed (foils are in waters way), reduced resistance at higher speeds (boat lifts earlier). As Silent Yachts are all about optimising efficiency. I was wondering if they have toyed with foils. Obviously the break even speed above which resistance becomes less would need to be sufficiently low. Preferably below or at low cruising speed. Not a good idea to make the most efficient speeds less efficient. But if the 40kw for 8knots could be lowered without affecting 6knot 20kw. Might be worth having higher sub 6knot energy consumption. Or slightly higher 6,8knot resistance but 10+knots significantly lowered....

anyway. thanks for all your coverage of these marvels. Looking forward to more. Tours of the 80? 120?

8 knots into a 10 knot sustained headwind???? Also, how about cruising in/out of the Haulover Inlet?

I wish they had a motor power curve on their website so it would be easier to calculate if it fits persons needs and also can you charge the batteries with shore power? I don't really like using generator so i would to charge it with shore power instead if solar is not enough. Maybe a 22kw type 2 charger would be good for this and it's relatively easy to install it too.

I like this guys honesty tbh. When the Silent 100 releases I might sell some crypto and buy one.

I understand the physics behind the trampolines in the bow of sailing catamarans ( we want the air pocket to release air pressure so we don't plain) , but on a plaining power boat wouldn't a solid bow aid in lift for plaining? Just wondering why they chose that design. ??

Why don't install solar panels on sides like sunreef eco? Thank You!

Michael each time I read more about you and your wife I hear only positive about what the two of you have worked so hard for past 30 years to finally achieve 6 models you can produce for sale to the public. You help me to push myself so I don’t give up. Can’t wait to see your next big breakthrough. Keep fighting, Thanks

This is good and honest. Is there any consideration to capturing potential energy from :

Small wind turbines
Propeller shafts
Cavitation from propeller wash

Thanks
