The rode locker on the CD 25 is enclosed, and a little larger than the CD 22. I have 15/300 rode in my 25, and could easily fit a little more. The rode I bought was Plastimo brand, and it has at times been a problem getting the windlass to feed it all into the locker. Not because of room, but because the rode wants to lay in small coils when fed in, and the pile gets too high in the center for the chain to sit on. I have to go up front, open the locker hatch, and spread the pile out when that happens. My CD 22 had S/L brand rode, and it fed in just fine. I am thinking if I had that brand on the 25, I could easily get 400' of it in the locker.
I see that your 25 Cruiser is brand new. Do you have it already, or awaiting an order delivery? Either way - congratulations!
