Fun in the water on Mars

Here's something that occurred to me the other day, If a soletta was used to warm Mars so that the ice melted, Mars would have enough water to cover its whole surface to a depth of 22 metres and only a fraction of that water would need to turn to vapor to give a high enough partial pressure to reach equilibrium.
Now, here's the fun part, while you still couldn't walk around on the surface of Mars without a space suit, it would only require scuba gear to swim in her seas!
