Draft maybe, permits? You couldn't make it around here in a 50' Wesmac. There's a guy down here w/ a 46' and sometimes he has a hard time when the water is low. I think their 50 footer draws at least another foot.
Why a 42, not 46? 55 or 56'' Wesmac would be my dream boat, but maybe not when it comes time to fuel up. Hard to beat what I've got now for efficiency, even w/ the old JT power.
The super 46 is not a plugged 50'.
Was told the 46 super wide started out in the 42 mold. They laid the keel of 42 along with some of the bottom area around the keel, then brought that over to the 50 mold inserted the 42 keel into 50 mold, blocked of 4 ft of transom and brought down the height of gunwales. After this was finished they created a new 46SW mold from this hull.
I have always wondered between engines is there a big difference in fuel burn if you are pushing the boat at the same speed. I have heard a lot of people say the cat c-18 burns more fuel than other engines. When the 42 Duffy sportfish from Texas, I think the name was Lady Dianna, had the fuel burn #s in the for sale add, I thought that as he dropped his speed from hi cruise to low cruise the mpg would increase, but it didn't seem to have much effect as I remember. In a hull such as the 46SW if you put the FPT 750, Volvo 900, CAT C-18, or Deere 750 and pushed them to the same 16 or 18 knots would there be a difference in fuel burn?
