In righting moment terms, height is just as important as weight so from a physics point of view the ideal is to be very tall and thin.
However, there is much discussion about weight ranges for boats but no mention of height at all. Some lard is going to help out of tacks and gybes in a trapeze boat where a lightweight would be in trouble if they didn't hit the wire quickly but for a good sailor it wouldn't be any slower. Is the difference seen in practice? |

The 700 equalises for height as well as weight, so yes it is considered and yes it is important!

It would be better to be very tall, but with a heavy head.

I think height is important in a lot of sports, however unlike weight it's not something you can control. Once your an adult you are stuck with what you've got. However that does beg the question, can you make yourself grow taller by eating the correct food as a child? |

I'm intrigued, how does that work then? Are the rack heights adjustable then? Yes height does matter, well it certainly does racing sailboards, so I guess it must be the same in dinghies for similar reasons. Tall thin = rig more upright, so in all the planing mid windspeeds advantageous, the only time I found short me could deal with tall them was when it was survival windy and everyone overpowered. So I suspect that might be the case in boats where speed and agility (something short folk are better and quicker at) are important. Edit in case anyone was wondering I'm 5'-6", least I was, knowing my luck I've probably shrunk by now and I'm also battling to bring the 70 kgs I've just hit, back to the 65-7kg range, never have I been so heavy at the end of the summer.

If it's the same as the 800 system, the racks are adjusted depending upon righting moment, which therefore includes height. A plank of known length is placed on scales, and you lie down on that, which gives the measure. The amount of lead you carry is dependent upon the all up weight. |

Of course height matters but you can't alter it very easily. However, note that variances in height are tiny compared to body weight. There are many people who weigh 50% more than me but not many that are 50% taller.
