Western, Gregor, Klamath transoms

I'm looking for a 12-14 ft aluminum boat and am inclined toward welded, rather than riveted boat like Gregor and Klamath (though I once had a Valco riveted that never leaked.) There are a number of Gregor and Klamath boats for sale used, but I also see a few Westerns. As I understand it Western, also welded, was sold to Klamath years ago but has a good reputation. The Gregors and Klamaths I'm looking at all have dropped transoms for 15" shaft motors while the Westerns' transoms are somewhat lower and straight across the stern. Can anyone offer me reasons why one or the other design is better? And any experience, good or bad, with any of these three boats?
thanks,
Larry

Larry - Welcome Aboard !!
you would have to add some more information of how
you will be using the boat - - - ocean, backwaters, rivers,
ponds, big lakes, deep water, yada yada yada
and what size motor would you use ??
The short transom is prone to being swamped from behind
if you get into a pickle with high winds and windswept waves
from the stern. Or, a big boat throwing a wake into your rear.
other than that, I can not think of any negatives of a short transom.
many many members here take it as a personal risk assessment.
The 14-15ft aluminum boats I have had had short transoms with a 25-35hp motor.
I think it boils down to your experience and seamanship in boat handling
to avoid situations that could swamp you from the stern.

be save - have fun !
