I've owned a single pump 190 and about to jump into a twin, and this got me into thinking about the old jet boat problem of debris entering our pumps.
It was while I was in the "no wake" zone that my theory hit me as I went through some floating Palm fronds and weed but came out unscathed. Now, I'm not saying single pump boats cannot suck in debris, that's just dumb, but my theory is there a lot less likely to, the reason being to the location of the intake grates.
As a single hull boat pushes through the water its displaced to the sides, so any floating debris is also pushed away from the boat, but at certain speeds some of it will naturally mix with the water and submerge. This is where my theory hits, a single pump boat has its intake grate at the lowest point of the hull, where twins have them either side a little way up from the keel, so, making ingress more likely.
I like to live by logic, and most of the time it works for me, making my theory logical Mr Spock
.
I've tried to illustrate my thoughts, a bit rough but I hope it gets my thinking across.
