20 or 25 knots with a 6.0.)

4.0 and 5.0 conditions are fairly different. In 5.0 conditions, sailing
a transition board is reasonable. It won't be very smooth: you'll
bounce a fair amount, but you'll still be able to control it. Jibes won't
be easy, because a board that size does not turn as promptly as a smaller
board, and you'll tend to bounce during the turn.
As the wind increases, and so does the chop, the bouncing will get worse.
In 4.0 conditions, the wind will noticeably push the board around when you
are in the air, and controlling it will be much harder. Very hard, in
fact. You'll have to depower the sail and slow down for fear of a slamming
death, while the folks with the short boards will zip all around you in
complete control. ---Luigi

I don't totally agree with this. The smallest size board that you can sail with
the PROPER size sail is the easist to sail and control in the chop and the
But I have found is if I am sailing really overpowered a board that little
larger is a little easier to control. I think the reason for this is that
if you don't have the smaller board under control you don't have proper
balance causing the board to be unstable. The larger (and wider) board will
be a little more stable.
When it gets to 35+ my 8'6" bump-and-jump board is getting to be a big board
and a 115L board is real big.

You can also go to the extreme of having as many boards and fins as you
do sails....then you get a horse van to carry them around in (I've seen
several). I carry 4 boards and could really do with another (9' glass)
for some conditions. Then again, this extreme is for trying to have the
"ideal" set-up to really enjoy the conditions.

Reminds me of Luigi's quote of "sailing is like standing in the shower
and tearing up $20 bills as fast as you can. Windsurfing is just the
same except you get to slam your body into the wall every few
minutes." or something to that effect!

Sail size vs Board size? Correct board size is affected by board speed
and water conditions. These two factors are in turn determined in large
part by wind speed. There is a correlation with sail size because sail
size is also largely determined by wind speed. So the general statement
that you need a smaller board for smaller sails is a pretty sound statement.
But, when this becomes mindless dogma it can lead you to automatic and
incorrect conclusions like:
"When I get down to my 5.0 sail I need to move down to my 8'6" board."
"My smallest board is an 8'6" so I have no use for a 4.0 or 3.5 sail!"
If you are sailing in a place with relatively quiet water you can use a
bigger board on a smaller sail. The advantage to this might be that you
could stay on a plane better through holes in the wind.
If a board becomes too big when the wind picks up to 5.0 conditions that
same board may be just fine if you drop down to a 4.5 sail. By doing
that you have essentially decreased your board speed. It wasn't that
your board couldn't handle a 5.0 sail. Its that your board couldn't handle
the speed that the 5.0 sail generated in that wind.
