R5 Onboard Cooler
R5 Onboard Cooler
Wondering what R series owners are doing to keep drinks cold. When its just a couple people a small cooler works - more people and more coolers take up to much space. We have tried to make the onboard cooler work but last weekend not much luck. Granted it was 100 degrees but I fed that thing a lot of ice. Feeding it the ice isn't really the problem but it won't keep things cold over night and starting with warm drinks just makes the whole problem worse. Ideas would be appreciated.

Re: R5 Onboard Cooler
We fill a large Igloo with ice and enough drinks to last the weekend.
We buy a 20 lb bag of ice at last place before marina.
We load drinks for the day, add 20 lb ice and it usually works for all day.
We leave the Igloo on the dock...it probably on have legs like a Yeti and won't run off.
At the end of the day, any ice and unused drinks go back to the Igloo.
Repeat the next day.

Re: R5 Onboard Cooler
So I popped out the subwoofer behind the Captain's seat to get a peak at the underside of the built in "cooler". I got a picture but it doesn't show much. I think there is less than 1" off spray foam on the outside of the cooler walls. There is more insulation in a $10 walmart cooler than is on this thing. The space under there is huge, it goes all the way to the bottom of the boat. I know it would help to add some insulation but don't want to make a mess under there. Also thought about filling the space with fiberglass insulation but don't know how it would react when wet. Anyone have other ideas?

Thanks...I didn't want to take anything apart to look. I was pretty sure of your findings by how much quicker ice melted in that one.FirstStar wrote: Sun Jul 11, 2021 8:49 pm So I popped out the subwoofer behind the Captain's seat to get a peak at the underside of the built in "cooler".

Re: R5 Onboard Cooler
On the first full day on the lake with lots of folks and drinks , I’ll throw 5 ea @ 10 lb bags and top-off the onboard ice chests in the morning. On a hot day, I’ll throw in another 2 bags late in the afternoon. As long as I don’t drain the water, I’ll have a little ice left over, and the drinks are still cold the next morning. On day 2, I’ll throw another 5 bags in the chests in the morning, and that will usually last us until the next morning. On my next outing, I’m going to throw a couple of Yeti Ice blocks in the bottom to see if they help. They certainly helped while I was at the beach last week; at the end of each day, I pulled the Yeti Ice with 2” of ice attached to it out of the bottom of my cooler.

Are you talking about the smaller cooler behind the helm or the bigger cooler at the co-captain duel seat?Luv2HuntAR wrote: Tue Jul 13, 2021 11:58 pm On the first full day on the lake with lots of folks and drinks , I’ll throw 5 ea @ 10 lb bags and top-off the onboard ice chests in the morning.

Re: R5 Onboard Cooler
On your boat, is there a noticeable difference between the two ice chests as to how fast the ice melts?Luv2HuntAR wrote: Wed Jul 14, 2021 10:49 pmI fill them both.Krob1114 wrote: Wed Jul 14, 2021 4:37 amAre you talking about the smaller cooler behind the helm or the bigger cooler at the co-captain duel seat?Luv2HuntAR wrote: Tue Jul 13, 2021 11:58 pm On the first full day on the lake with lots of folks and drinks , I’ll throw 5 ea @ 10 lb bags and top-off the onboard ice chests in the morning.

I agree. Spray foam I could get at the home center seems messy. Anyone have thoughts about a method I couldn't mess up?Big Block Power wrote: Sun Jul 11, 2021 9:38 pm I guess I would use more spray foam. Wet pink insulation is no good.

Re: R5 Onboard Cooler
Built in cooler under passenger seat seems like it is actually a cooler and the one behind drivers seat is a space that can be used as a cooler but not really insulated. I sometimes used cooler under passenger seat but put a soft cooler inside the other one.

Re: R5 Onboard Cooler
Good question. Had to think about this one. I’m thinking the bigger cooler at the co-captain seat keeps ice a little better.Krob1114 wrote: Thu Jul 15, 2021 4:05 amOn your boat, is there a noticeable difference between the two ice chests as to how fast the ice melts?Luv2HuntAR wrote: Wed Jul 14, 2021 10:49 pmI fill them both.Krob1114 wrote: Wed Jul 14, 2021 4:37 am

Re: R5 Onboard Cooler
Yes, some say it's a cooler. I think it's more like a wet well. I've seen sales videos from different dealers, some say it's insulated, others say it's not.Luv2HuntAR wrote: Wed Jul 14, 2021 10:49 pmI fill them both.Krob1114 wrote: Wed Jul 14, 2021 4:37 amAre you talking about the smaller cooler behind the helm or the bigger cooler at the co-captain duel seat?Luv2HuntAR wrote: Tue Jul 13, 2021 11:58 pm On the first full day on the lake with lots of folks and drinks , I’ll throw 5 ea @ 10 lb bags and top-off the onboard ice chests in the morning.

Re: R5 Onboard Cooler
I say I've never used a cooler on a boat. We just pack one. Our cooler holds our towels.

Re: R5 Onboard Cooler
Mine does have some foam insulation, maybe an inch or less. Not sure why they wouldn't have put more. I would spray more if I didn't think it would make a big mess.Krob1114 wrote: Fri Jul 16, 2021 4:05 amYes, some say it's a cooler. I think it's more like a wet well.

When it's just us we normally bring a separate cooler but when we have a full boat there isn't room for all the coolers. I guess I'll just bite the bullet and buy more ice. Small price to pay for such an awesome boat!
