yep, they are just placeholders at the minute mike.
I'm getting the general layout and then will be modelling all the parts.
I'm torn between whether to make the supports really lightweight for example in the future building materials can be any diimension and still strong enough - or go more traditional and make the supports thicken out at the base as they enter the water...
plenty more things to think about and finalise!
thanks for the tip THX1138 - I'll have a look. The supports will be futuristic as I'm trying to get away from the traditional look. It's not definate yet though
twisteddragon33 - good point, looks like I'll be doing a few different designs and seeing what people prefer. Maybe something between the current ones and the traditional ones might give the 'support' that it needs
