Install Calibre on a computer and use that. Browse online sailing forums for your favourite books and new releases. Then support the authors financially by buying their paper books directly from them or their publishers.
If you buy your books from them digitally use a DRM remover (Like the plugin available on Calibre) so you can forever own your books and move them to any device you want in any format you want. Forever.
