No boating for two years? I'd rather go without sex for two years!
Seriously, you're not that far from the coast. Maybe you can find somewhere to stay on the weekends. Some of you fresh water guys talk like your boat is going to immediatly disintegrate if it touches salt water.
One more thing, if the government is involved in this project and they say two years, you never know what will happen. Maybe it won't happen at all? maybe it will be four years?
