Tie Down Tracks and Motor Whale Boat

Hi there,
I´m currently (to be honest since 1 1/2years) working on a large scale Model of an CVE in the scale of 1:72. It´s going to be the USS Sangamon CVE-26. On of my next steps will be the Flight Deck and I´m still looking for those Tie Down Tracks. So far I have found nothing which I could use and printed ones are simply not looking good enough. Does someone knew about photo-etched Tie Down Tracks? Additional I´m searching for the 26" Motor Whale Boats in the same scale (1:72). Off Course there are a lot more things I´m looking for cause this model is going to awful big and the ammount of details is horrifying but I started with it and now I have to finish that monster. Any help would be great and anyone who is building something similar
it would be great to share some experiences.

Keep on modelling!
