Tube pressure in winter

Hi, in two days iâ€™ll go with mi AFC in Como lake.
It will be the first time with my kayak in winter season, now we have a temperature of the water about 4C-39,2F.
I would like to know if is better to increase the pressure of the main chamber and the floor too or to inflate at stock pressure (2PSI main chamber and 1PSI floor).
Thank you.

I would be inclined to stick to the standard pressure myself.
But check once the Kayak has been in the water for a while and top up if need be , just watch out if you leave the yak on land in the sun!

Tank you for you reply, the site that you linked write:
Cold Weather If you are paddling in the winter time when the air and water are extremely cold then you just need to be aware of the pressure of your kayak. Remember in cold weather you will lose air pressure. Therefore after you have paddled for a several hours you will likely need to check your air pressure and possibly add more air.

If inflatablekayakworld doesn't mistake i must take with me the pump,check the pressure and probably add air.

The best way to do it is to inflate your kayak to the proper pressure (2.0 psi) or a little more at 2.5 psi and then let your kayak acclimate to the water. Once it has acclimated to the water temperature, add more pressure. I know that it takes more time to do it this way, but its better than risking over inflation!

For the floor, definitely only inflate to 1.0 psi. You could damage it by initially over inflating to compensate. If it does go soft, add pressure then, but not before.

Thank you for your reply,
i think that your way is the best but unfortunately i have not time to wait that the kayak has acclimated.
I'll inflate at 2PSI and i'll take with me my pump to add pressure if necessary.
Floor:ok at 1 PSI and no more

For the AE1007-R Convertible kayak, you should inflate to min. 2.5 psi before hitting the water. That pressure will be perfect but will decrease in the cooler water to 2 psi. You can even go up to 3 psi if you want. I usually do because then it drops down to where I want it to be.

Finally i made my excursion, i inflated at 2,3 PSI and i checked the pressure after two hours: the pressure was not changed.
May be because the air temperature was the same that water temperature?

I'd just like to observe that it's no real problem if the water is cold. Inflate the normal amount. I don't find that the cold makes my kayak look under-inflated after a while. And I don't mind paddling it at 90% full anyways

These kayaks handle pretty darned well at 90% inflation. Bringing your pump along to top up if necessary is a good idea too.
