| 49 | The Atlantic waves are quite an obstacle for a 2m boat.\r |

| 58 | It is not that easy. If you just start sailing in a straight\r |
| 59 | line, you will end up many kilometers above the sea, which is\r |
| 60 | no good for a sail boat. If instead you point the boat\r |
| 61 | straight at the finish line, you'll be under water for most\r |
| 62 | of the trip. Again, not ideal for a sail boat. The earth is\r |
| 63 | not flat, you know.\r |

| 89 | You are saying that as if it is a problem to hit C,\r |
| 90 | like it would be impossible to continue after 354\r |

| 141 | I imagine that's true, if you have an effectively unlimited\r |
| 142 | energy, but the terms of this contest is to build a vehicle\r |
| 143 | less than eight feet long that can cross the Atlantic.\r |
| 144 | That's not a lot of room to stuff with batteries or diesel\r |
| 145 | fuel, or to cover with solar panels. And that's the whole\r |
| 146 | point. If you could make the vehicle a hundred feet long,\r |
| 147 | this challenge would be expensive, but easy. By making the\r |
| 148 | boat tiny, you make the challenge affordable, but tough.\r |
| 149 | The race has two divisions, sail powered and unlimited, but\r |
| 150 | it's hard to see what they had in mind for propulsion by\r |
| 151 | having an unlimited division. Possibly some\r |
| 152 | seawater-replenished fuel cell.\r |

| 160 | Being small means relative high strength. A solid two\r |
| 161 | meter boat should indestructible by waves. No need to\r |
| 162 | keep a human alive, nor to go very fast. A very basic,\r |
| 163 | fixed, small but strong sail would do.\r |
| 164 | Ice bergs could be a problem. Surely better to start\r |
| 165 | further south. Longer but safer. Also need to stay out\r |
| 166 | of shipping lanes.\r |
| 167 | I think this could be done without a computer. Just a\r |
| 168 | magnetic compass controlling a rudder. Occasionally it\r |
| 169 | would be blown backwards but no big deal. No need to\r |

| 205 | This is a 2 meter vessel, not a large racing hull built to be\r |
| 206 | fast (and nothing but fast). Using the page you link to, the\r |
| 207 | most useful comparison would be the single-handed records,\r |
| 208 | and the one from 1987 which was about 11.5 days was in a 26\r |
| 209 | meter hull! And this is the smallest vessel on the list. You\r |
| 210 | are probably not going to get a 2 meter vessel to tear along\r |
| 211 | at an average speed of 7.5 m/sec which would be needed for\r |
| 212 | that 11.5 day crossing.\r |

| 224 | Tom MacNally aboard the Vera Hugh (1.64m) in 134 days in\r |
| 225 | 1993.\r |
| 226 | Hugo Vihlen again aboard the Father's Day (1.62m) in 115\r |
| 227 | days in 1993.\r |
| 228 | Tom MacNally unsuccessfully attempted the trip again\r |

| 243 | Also note that the world speed record for a radio-controlled\r |
| 244 | sailing vessel (which was also 2 meters long) is [1]157.65 km\r |
| 245 | in 23 hours 42 min [guinnessworldrecords.com] in the milder\r |
| 246 | waters of the Mediterranean. At that world record speed in a\r |
