It depends on your bimini
If you haven't bought the bimini yet, it might be best to have one custom made. AmeriSeam does good canvas work, and they probably have a pattern for the H23, so it shouldn't be much more expensive than buying a generic one off the shelf. You can get in touch with AmeriSeam through the Hunter factory.If you already have the bimini and it won't fit, you can probably shorten the frame to make it fit under the boom. Good luck.PeterS/V Raven
