My basic thinking of using a high capacity pump is to buy some time while trying to sort out a possible failed fitting or whatever is the problem. Beyond that it would merely be a helpful tool delaying the inevitable while grabbing the ditch bag and deploying the life raft. Even then, as past cases have shown, it may not help at all because events
are happening too fast such as a major hull breach. The fact is if it doesn't require a lot of space to store, isn't too expensive, low maintenance
and easy to deploy chances are you may want to have it on board to use when needed. After all what's the downside?
mats.... now there's another subject that could be discussed particularly now there is all that junk headed to the west coast
from the Japan
tragedy. Already items are being found on the Pacific NW beaches well ahead of predictions.
Thanks to all for the links and info.
