Jumping into a lake when the water temp is cooler than you are can be dangerous. Be careful. I try to ease into the water and I keep a line attached to me.

Don't wait till your thirsty to drink. Your late! Start drinking within the first hour. Nutritionist say water, water and more water is the best. Like said earlier start the day before and not alcohol. Use a face shield starting in the morning. Drank 15 bottles of water Saturday, ate breakfast and jerky for lunch and was great all day. Did take a 15 minute break for a boat ride. Hydration is the key. I like my ears the way they are so the face shield. BE CAREFUL and don't wait till your thirsty.

I just ordered a chair umbrella to see how that works. Have used a patio umbrella in the past but it's a pain adjusting everytime you move. Can't deal with the heat like I used to so I'll try anything. Ditto on all the other suggestions.

You'd be amazed what cool feet can do for your day. Wearing long sleeves and buffs help for the body but when it comes to feet I wear flip flops or crocs so they can breath, carpet can get hot so I don't typically go barefoot. Also it helps to stick the legs of the edge in the water while you drink a water or eat a sandwich. Trust me for all the avid shoe wearers. On a hot day, take the shoes and socks off and tell me you don't feel better.

Long sleeve Columbia shirts, buffs, Boone hat, and start fishing at night.

Definitely long sleeve dry fit type clothing. Plenty of water and if I know I'm going to be out there a long tournament day, I start out with pedialite in the morning. Excessive sweating while drinking only water will deplete your electrolytes

My only issue with a face shield is covering my mouth holding hot air in. Wearing long sleeves is cooler. It provides shade to the body

I am going to add a bimini top to my boat. Had one on the last one and just getting out of the sun for a few minutes is a game changer. One over the console area providing shade when you drive will feel about 10 degrees cooler

This is the best I have found.

I saw a guy last year on PK with leggings, shorts, performance type long sleeve shirt, face shield and hat. I can see why now. I'm just a little leery about the leggings. I know it was probably more for sunburn than coolshade but I don't mind putting some sunblock on my legs and moving on. Anyone else wear long (breathable) pants or leggings with shorts? Yes it did look strange which is why I don't know if I will do it, wondering who else does though.....

I bought one of these portable misting fans to use at my son's games/tournaments during the hot months. It more than paid for itself the first time we used it. It sits on a 5 gal bucket, and runs off the ryobi 1 battery. It does put out quite a bit of moisture but would work well in a boat.

I wear long Magellan pants. Year round. I feel much cooler if I can have no place on my body where the sun is hitting me. Totally covered head to toe.

Man, if that thing had a solar device on it that would be great. I did not read how much water it holds so I would like one that sucks the water out of the 5 gal. bucket. This would give you hours on end of cool air. I see it also plugs into electricity.

Good info so far. Number 1 is hydration BEFOREHAND! I keep my ChillyPad (Frog Toggs) moist in the refrigerator. I drop it in the ice chest on the way to the lake, when it starts to get bad, drape it on my neck. Can always recharge with melting ice as needed. Especially at the end of the day to cool me down before the loading and prepping of the boat for transit.

It does sit on top of a 5 gal bucket filled with water. The fan has a pump that draws water from the bucket. Each battery last about 2 hrs. I bought 2 extra ryobi 1 batteries and make sure all are charged.
