Abstract
New electric boat designs are provided that exploit the weight of a battery to stabilize the boat and in some cases to overcome the hull speed limitation problem. The battery mass is enclosed in one or two torpedo-like structures that are mostly or completely submerged. A platform is spaced above the torpedo(s) via one or more struts that may allow wave energy to pass through the watercraft rather than collide with large vertical surfaces. The design minimizes wake formation, wave sensitivity and is useful for new kinds of electric boats that can dive with an air bubble to allow submarine use, higher speed pleasure craft, and sailing craft that can remain stable in shallow draft waters. The stabilized watercraft optionally have computer monitoring of wave activity and control for greater resistance to adverse weather conditions.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
