Hi Dave,
Your 200lbs is about 91kg, not really that heavy - the top 2 Mozzie sailors here are about that, then they have crew at about 55-60kg (130lbs), so they`re 330lbs all-up, on 16ft boats with 16sqm sail area upwind & 14sqm spinnakers (about 160sqft main & jib, 140sqft spi.)
Then again, we have either NO wind, or HEAPS of it. In summer we wait until 4pm, where conditions change from not enough to hold a race, to 22-25knots, the transition normally takes about 5 minutes. Kinda weird, paddle out to the start line & then sail in survival conditions.
At the Round Robben Island Race (The prison in which Nelson Mandela spent way too much of his life), the race got off in light breeze, then died away leaving the competitors drifting behind the island. The ride home got interesting when 30knots came through.
In winter, it either rains with lots of wind, or rains with no wind, although right now it`s a beautiful sunny day, 23degC midwinter, and I`m stuck behind my PC. Rain is forecast for the weekend, typical.


Cheers
Steve
