Translate this cause of death death

Can someone who can read Norwegian tell me if the final entry off to the right (on the facing page) is the cause of death for my Gr-Gr Grandfather Helge Andersen (62) and his son Mattheus (19)? They both appear to have died on the very same day and I thought maybe it said something about a storm and no survivors....or "something" and no survivors. They are from Sorgjeslingen Farm in Nærøy, Nord-Trøndelag. Their names are at the very bottom #348 and 349.on this page: http://www.arkivverket.no/URN:kb_read?idx_kildeid=2524&idx_id=2524&uid=ny&idx_side=-262 Thank you.
