Interesting point about the yaw. It estimated the water level and made a quick check on my CAD model. It seems that LCF is close to LCB. I will...
The balance will be achieved later by manufacturing the keel after I build the whole boat (without keel). Now I have a rough estimate about the...
I see. Thinking out loud, having the stern very thin would significantly reduce robustness, i.e. I would have to remove some part of the inner...
I noted a few posts back that the wingsail is buoyant, so the boat won't capsize. It displaces 13kg of water which is even two times more weight...
Hi, here are the pictures of the design as promised! Any feedback is appreciated. [ATTACH] [ATTACH] [ATTACH] [ATTACH] In the picture above,...
This will be my priority to hide everything that can catch seaweed if possible. Also the keel will be swept-back and the bulb won't stick out in...
Do you mean mechanically fragile or does it have another meaning? The whole thing will be made from carbon fiber + Kevlar and all the rods you see...
Thanks, I will post the CAD design of the 2-meter hull when it's ready. I will have to tweak the "standard" competitive shape a little, because...
I mean that there are two things that will happen when I add the side floats: 1) The added resistance of the floats will decrease the speed. 2)...
Without the side floats, the boat may lean too much. It's critical for the correct wingsail operation (the "flap" must not enter the water). The...
Hi all, I would like you to confirm if my approach of designing a proper rig is correct. I am designing a 2-meter autonomous boat that will sail...
Thank you for your valuable comments! I will use the gelcoat.
I am building a 2-meter autonomous boat that will attempt to cross the Atlantic, so it will stay in the ocean for months. I want to paint it with...
It will tack, because it's optimal in terms of speed as you described. I want to say that it's not critical for the long-term mission. I have seen...
I didn't make these assumptions, I have guessed that the preferable wind direction would be approximately sideways just to stress that this boat...
What about a shielded rudder like this? [ATTACH] It's a cross section. The shield would cover the full range +/- 30 degrees for all rudder...
Good suggestion. But first, I will try it with the center of effort of the sail exactly above the keel's CLP, because I don't know how "little...
Sorry about my ignorance, but you ignore my concept. There are two worst wind directions: upwind and downwind. I guess the boat will be fastest...
You are right that seaweed will wrap around the leading edge when the boat is moving forward, but I am worried more about periods when the boat...
The sailwing will be freely rotating in the direction of the wind +/- some small angle adjusted by the tail. I don't think you will find it in...
