i agree with the points Gdavid made. that skiff will be very tender. if you don't stay in the center of it when boarding it will flip you out in the blink of an eye.
i tried a very similar dinghy to tow behind my sailboat as they have almost zero drag. i ended up in the drink the first time i got in it. it was super easy to tow, but really impractical for me and my wife. and we're weren't exactly big either, maybe 275 pounds combined.
i much prefer a wide, stable dinghy.
