Sometimes running up on plane helps if the conditions are right. For instance heading east on the bank out of cat cat there is a shallow area about 6 or 7 Nm with about 6’ MLW. All flat sand, no coral. at dead low tide, a boat with a 5’ draft will squat at hull speed leaving very little clearance, if any. Moreover, in shallow water instead of doing 10kts, speed will drop to 8 kts... Whenever we go thru the area at low tide, I usually run on plane at 20/22 kts. No risks and the sounder reflects the boat riding about a foot higher in the water.
