The only wrinkle for me is additional holes in the hull. Enter the Isotherm option. Same principle but no extra holes.
Does anyone have experience of how the two set ups compare? Performance and efficiency? Pros and Cons for each system?

We have the frigoboat w/the
keel cooler in a stand alone fridge and it works well. We looked at the isotherm w/drain
heat exchanger before
purchasing the frigoboat and if my memory is correct, the BTU exchange off the
keel cooler was greater than the drain
heat exchanger. I took this to mean less run time to remove the same amount of heat from the box.
Our 6 cu. ft. box is only a fridge and now w/the
water temp at 70F we use less than 30 ah/day to keep the box at ~35F. Maybe 35-40 ah when the
water temp is up to 85F in the summer.
Not sure if the isotherm is a capillary system also.
W/the
keel cooled frigoboat (probably the isotherm also) if you
haul out, you will need the auxiliary fan to run the fridge
on the hard. Can do a fan "add on", but if
buying a new system would get the combo right off the bat.
