To begin with, I sail with all boats and crew sizes on a regular basis. Last night, I began playing by sailing solo. I had three skulls and two chest on board.
I got greedy and dove down on a shipwreck. As I surfaced I saw a two man sloop approaching in the distance. I had time to fire two cannon shots with one landing. I lifted the anchor right afterwards.
The enemy ship caught a gust of wind and hit my sloop and boarded. I dueled the one pirate as his crew member patched the holes. I died only to be spawn killed.
Scuttle the boat they say. Do you want to waste an hour or more a night on nothing? If Rare fixed the spawning issue, one might stand a chance of simply not giving away your hard earned treasure due to poor game dynamics.
There is a simple solution if the respawn position cannot be fixed due to limited ship space depending on size. Give a respawn health buff when on your own ship. This would make other pirates want to take a chest or two and go. Leaving the solo player with more reason to try and sail alone either by choice or lack of friends online.
