Since the space on your boat is so precious, before you buy, measure up some possible storage areas.
Having coolers that fit your boat is really helpful.
We have nothing fancy. 3 Coleman extreme marine coolers. Two of them over 10years old. They keep ice well. The 100 litre one fits perfectly in the floor of the cuddy of our Double Eagle 206. We put salt ice in it last July and put it down in the cuddy. Didn’t start using it for maybe 4 days still had ice on day 9 to transfer to our little Calcutta fish bag. The little Calcutta 36” bag fits in side pockets on the boat when not being used or also in the floor of the cuddy, out of the way and out of the sun.
