Feel free to ask your Funeral Director who coordinated the cremation for assistance. It is usually considered part of his fee.

1) the completed Arrangement Form,
2) the completed Document of Authorization for Scattering of Cremated Remains At Sea,

Unfortunately, this would necessitate a charter arrangement, for which our vessels are not fitted, registered, or insured. Such charter arrangements, moreover, would negate the economical essence of the unattended service. For these reasons, our scatterings are "unattended".

The Captain, usually with a crew member, sail the cremated remains to a suitable burial location that is in accordance with all laws and regulations. There, using a traditional nautical maneuver called "heaving to," whereby way is nearly stopped" - that is, the jib is shortened and backed to windward, the mainsheet eased, and helm adjusted to windward so that the vessel, balanced between wind and tide, rides smoothly in place with little or no forward motion. 
 

The Traditional Burial At Sea Ceremony is performed by either scattering the ashes upon the surface of the sea or tipping to the ashes to the sea bed in a sealed urn, accompanied by an appropriate reading.  A personalized copy of the requested ceremony is provided to the family along with the Certificate of Burial at Sea, and a sea chart indicating the location of the scattering service.

Weather, wind, and tide play major (occasionally hazardous) roles in sailing. This is why we use the term "weather permitting." In the winter months, when the harbors are frozen, vessels are laid up on land and overhauled. Moreover, we plan our voyages to arrive at the selected burial location on an ebbing tide, as tradition dictates.

The absolutely least expensive option must be anatomical donation. Most medical schools accept anatomical donations for biomedical research and the training of Physicians, Surgeons, Dentists, and other Health Care Professionals. The body must meet certain criteria to be useful for teaching or research. If he distance between the place of death and the medical school is reasonable, there is little or no cost to the family. While studies may take up to two years, the medical school will transport, cremate, and return the ashes at their expense. You will have an option as to final disposition of the ashes: You may wish the ashes to be returned to your family for burial in a family plot or for scattering. Obviously, anatomical donation will not appeal to everyone; but if you are interested in considering the ultimate and most humanitarian "Gift of Life," look first to the medical school closest to your residence.
