The lack of a civi boat is a problem - I just couldn't bring myself to use one of the military ones, I had no idea how on earth could I explain it
You don't. Just give it 3/4 fuel (to simulate the journey, it has to be more than half since you are planning on getting back) and bit of damage and little or no ammo, not that that really matters.
We all know you have to compromise a little in OFP and in this particular case we also know that all kinds of wild and strange things are happening on the island. A slightly odd boat is nothing.
The alternative - no boat - also looks odd. So its all a question of what is the least worst option. My vote is a Soviet boat.
When running around the little pier place, I did consider suggesting a ruin with an old fisherman, who you knew at least by reputation as somebody who might help you. I didn't mention it because it means a whole extra cutscene, and right at the start of the mission. But if you're willing to consider that anyway .....
Fh70 is ok as a house - he cann snuggle down between the wall and the building - but the location is too exposed. It's also too far away. With no 4x, and needing to be a bit tactical, it could take you the best part of an hour to get to Vigny and that really is too long.
Starting right on top of Vigny is also no good, you need the space.
When stuck, return to first principles.....
There are three plausible islands for where you are living. The bare island where the intro is shot; lighthouse island immediately to its south, and island point 15 south of Kassalon (as I call the Desert Island shaped isand). All on the east side. Kassalon and Airstrip Island would both be inhabited by marauding bands of soldiers. The other islands are little more than rocks.
Let us assume that it is obvious that the main airport is going to be thick with soldiers and let us also assume that you have a suspicion of lots of soldiers in the main towns in the south.
Because it is shorter, and avoids the airport, you will come round the south of the Malden. Your possible landing areas are:
- La Riviere jetty, particularly if you are short of boat fuel and think it would be safe to go there. Or maybe south of Cancon but its a long way to Vigny and dangerous.
- the southern tip of the SW peninsula, though only if you know you can get transport at the lighthousekeepers' cottages
- the jetty, where there are facilities for boats and possibly an old fisherman. Or the beach around there.
- Vigny fjord if you have the bottle to get in
Most of the western side of Malden is rocky and very open to weather from the west and is not suitable either for landing or leaving your boat on a filthy night.
I think you should start on the shore near the boat, for realism reasons. (Or in the boat.)
The other alternative of course is that fuel is very short and you land on the east coast in the Dourdan/Houdan area and go straight across the island via Arudy.
Or use the Cessna somehow.
