A new Fishing trawler Anabela - sailable found under Vehicles / Miscellaneous Vehicles, cost 0.
How this works:
Firstly you need Island Paradise. Then you need a port. In this port you need to create a 20x6 barge. You then use the game cheat moveobjects on and place the fishing trawler over the barge.
If you don't know how to build a port or a barge please go to the EA site, there are plenty posts there to help you.

PS This is an improvement to the trawler Gail. It's a different mesh. The Sim can now walk around the rear deck and his feet are not chopped off. The 2 anchors have now been placed correctly. I've re-coloured the barge floor to match the trawler.
