Looks like the ideal weight for the front part of the boat is 155 lbs since the drivers are all 175+ it would seem...
Actually it would be best to turn that around. To have a 155 lbs skipper and a 175 lbs crew. While going downwind you need the crew on the wire in a blow so more weight out is best. Going to weather you want the strongest person as the crew so they can play the mainsheet. Having said that I think that you can have more weight on the boat than you are giving credit for. Some of the designs can carry 360 as a combined crew weight just fine.
As for Mr M. Sometimes for the benefit of job security you need to chase across the country. One or the other parent has to choose to raise one's children or you pick a stranger do it. He has put his career on hold to support the efforts of his wife who is a really dedicated worker and seems to love her chosen occupation. Though he is not punching a clock he keeps pretty darn busy. Even without being able to say I am a "fill in the blank" right now, he is always working on something for some company or other. A bonus is that he is always in contact with his child. He was part of the family's decision to move from Paradise to.....well Paradise. I say Bravo for a courageous choice!
