check the 285 specs
Sara,
The uploaded specs should have some of the rigging information you're looking for if you're re-rigging the boat, but tension and rake won't be there. Regarding the shower, it drains to the bilge, at least mine did, so you need to have your bilge pump on when taking a shower. I've heard of others that have setup a pump and float swith in the pan of the shower and pump directly out rather than flood the bilge ( and it doesn't take much with that small bilge area.) Biggest headache I had was the windows leaking. I used to replace the barrel nuts and regasket every year. Finally went to calk and gasket which lasted me two years until I sold her.
Fun boat.. enjoy..
