Bow Tank Setup

My personal preference is pick up only and electric pump to empty. Remember to vent it well

The problem with having a pump as the only method of emptying is of course what to do when the pump packs up. Pumps fail, switches fail and wiring fails. I drove a boat in this year's Diamond Race in Belgium when neither of the pumps worked so I couldn't empty either the bow or belly tanks. I think it ended up being towed home full of water!

My preference would be to have both the old fashioned gravity system and if possible to add pumps to speed things up. This also allows you to empty tanks while stationary.

I used to have a gravity system in my 18, using 2" pipe the transom and a ball valve but I would not leave the boat in the water unattended. Just personal preference. I don't like holes low in the transom

1 litre of water weighs around 1kg, so how much weight do you need?

not to big

are we talking ski racing or just the boat ? if its the later just remember more weight = less speed and the more weight the more chance of stuffing it
just my opinion (my p18 has a 40 litre one just in front of the foot plate that works well)

Brass gate valves are no problem and as Gary says less to go wrong
