How much water do you need?

[leetudor]

Was cruising in some new areas this afternoon and started think about how much water would our boats need at a cruising speed?

Draft is just shy of 2' on a Saltare to the lowest point, the rudder. On plane obviously it's less water. When I used to ride a protected creek I've seen the depth gauge bouncing between 1'-2' at low tide when turning at either end of the stretch we rode, that was before I set it to correct for 1' that I assume the running gear hangs below where I have the transducer mounted, right under the transmission output flange. Had some pucker factor at low tide but it was a soft sandy bottom in that area and I knew it pretty well, never struck anything.

Numbers sound about right. One must always consider the cost of failure. You may feel better about the soft sandy bottom, but as the water gets thin, you start to suck in mud and sand into the transmission cooler. We boat in some shallow water and managed to overheat the engine when the transmission cooler got totally impacted while forging through a short, but shallow, muddy bit in the river. We shut down quickly and clean out the mess and seems everything is ok now.

I agree with you. You must consider the cost of failure. There are a variety of situations. I had similar problem with cooler.
