Force 7 Ocean Wave

- I think ... if we put a "rear wing" on it ... we would transform it into a Formula 1.

The funny thing about the case is that the honest 'Seat 600' reached a top speed of 20 knots in a tremendous surf controlled by a clumsy autopilot with little more brain than a crystal radio.

 

(Here I had put a music video from 1975 created today)

Music that never existed, this phenomenon that has just been born with artificial intelligence is surprising.

My fantasy is a MiniTransat type sailboat that would have been possible in 1979.

A small step forward following American Express

Hull: 10 mm Plywood Okume, and i think the frames (and the deck) could be made of 15 mm Paulownia and thus not waste the grain orientation, and we would achieve the objective of 400 kg

- A sailboat to enjoy. You're completely crazy. What's next? Adding a motor? You're ruining our glorious tradition of wooden boats and iron men.

Motor

A) Honda 2.3
B) Honda 2.3 Copy
C) Haswing Protruar 3.0 12 volt

PROTRUAR BRUSHLESS MOTOR 3.0 12V https://haswingoutdoor.com/products/protruar-brushless-motor-3-0-12v

D) Protruar 3.0 24 volt
E) Protruar 5.0 24 volt

In any case 2 x 100 w solar panel, because one port and one starboard

(You can't imagine how many hours I've wasted trying to fit 1 fuxxx solar panel on the deck)



(The little Suzuki is more powerful; but the Honda is my favorite)

 

I have seen an 80 ton Baltic Trader towed cross an anchorage by an inflatabubble with a 2.5hp Yamaha.

 

Let's assume a case: crossing the Barbuda lagoon against a strong trade wind.

(And a 24-volt battery weighs 20 kilos)

The most logical thing to me seems to be plan A and plan B.

 

Anchor

Richard Danforth-type anchors are magnificent and very inexpensive.

But with their very long blades, they don't fit: the anchor hangs angled at the bow on a steel rail, and since it's a very small and light boat, it only has a line without a chain, and the anchor can be lowered and raised without stepping on the deck.

I've had a Mantus M1 for years, and I'm very very happy: it's a magnificent anchor, although it's expensive.

I think it comical that this lengthy thread is mostly you agreeing with yourself.

 

If you feel the need to attack people, I suggest you go to the WBF and have at it.

 

Since when did radar reflectors get so expensive? I always fitted Firdell Blipper as i was consistently told i had a good "contact" by watch keepers on large commercial shops. Perhaps an AIS transponder is the way forward.

 

Yes, all these devices aren't worth their price.

It's mostly to maintain symmetry with the VHF antenna, haha

It's a large reflector, and I found a very interesting study, and it sort of works. There aren't many options; the active one is very expensive.

(The bitter and ignorant on duty deserves a psychiatric examination)

 

Right. I owe an apology.

 

With the radar reflector and the 5-watt all-round white light, we have reached the end.
