I've got a squirt boat bag made for an asylum. It's got a fleece interior and velcro closure. Two handles for easy carrying.
I used it once on a cross country trip about 14 years ago and haven't had a need for it since. Taking up space and we're purging all things unused.
Let me know if you're interested. Could be modified to fit your boat. The bag picked up dust off the garage floor as I took these photos so that is what the grey blotches are.
I'll let it go for $80. I'll ship it for another $10. I can take paypal and have it on it's way to you today.
Custom bag would likely run you about $200 these days.
