[CQ-Contest] Are beams needed for competitive contesting from the Caribbean?

[Rudy Bakalov]

The subject says it all. I was wondering what the experience of those of you who have contested from the Caribbean is. Assuming running full 1500W power, is a beam really required? Is it more important to hear well than to be heard (my assumption)?
So, here's the big picture- we have a vacation rental property on HR9 and I'd like to make it available to hams/contesters as well. On the flip side, I am very concerned about the appearance of towers, beams, etc.
>From HR9, I really need to directions- 330 for NA and 30 for EU. I can do them easily with two OCF dipoles. The dipoles will be about 30' up, the property is on a hill and the elevation drops by about 20' about 30 yards from the house and a total of 130' about 500 yards from the house. Further, I plan on building full size verticals for 40 and 80 and some sort of a full size sloping vertical for 160. 4SQ RX plus beverages in the two directions I mentioned already.
Is this setup enough for competitive SOAB effort/score? Do I need to include a tower, rotator, and a beam? The maintenance of anything in the Caribbean scares the heck out of me.
