Condolences to the deceased indeed.
How does this happen BL? In a word, stability. A gentleman recently inquired about stability of his Nordic Tug and I was appalled by the replies he received from supposedly licensed "masters". This is where the rubber meets the road on stability. If you calculate it wrong, even on boats that have operated fine for years, lives will often be lost.
