If TP's masts are submerged, then she will have capsized and will be offering the same footprint as a 120 foot motor vessel - she is a big boat. If too far aft you begin to surf. The slow parts of the surf cancel out the fast speeds gained on top of the waves. Quartering wind allows them to run down the waves. Large Waves cause the boat to run into the back of waves, this creates sudden stop low speed and damge to boat, crew and gear.
Weather is top priority for navigator.
Avoid gales their large waves aren't fast. For records the less sail changes the better. They can take 40 minutes. When Playstation the first purpose built Race class cat was launched in 1999, the 24 hour sailing record stood at 540 miles. Playstation soon bested this knocking it up to 580 miles.
