Hi Andrew, it looks like Scotch Bonnet is in good shape again, after that amazing odyssey. I am impressed that you did not give up on her! Christian 411/028 |

One of our bilge pumps connects to one of the aft cockpit drains via a Y piece, down by the overboard discharge. I recall at the time the surveyor didn't really like this arrangement, but agreed it was Ok in this particular instance. This followed a long discussion on exactly the points that Lars raises.

The history of the Rule is interesting, do you know Lars if it was exactly the element of our design which was found to be dangerous or were there more dangerous designs and we have been caught in the overall solution? In fact looking at our design I can only imagine gravity would stop the cockpit water rushing out as intended if the existing drain exits were immersed, and if that were the case and we installed new dedicated bilge pump skin fittings next to the current exits, we would potentially have similar problem with the ocean entering? Until starting this exercise I've been a fan of the effectiveness of the combination of our cockpit and drain size as well as the bridge deck, having filled up to the coamings a number of times I thought it drained very efficiently. So I''m not currently worried about the safety element of our design but am keen to hear from our S&S racers whether this caused them any problems with their safety audits and if they were obliged to change design? Many thanks all for your time and advice. Andrew 41/039 |

Thank you very much Lars, we will submit to the safety audit with these possible solutions in mind, if the auditor requires. Philippe, thank you for raising such a good point, I for one hadn't thought of that. Do you replace the pump membrane periodically as a service item or only when signs of deterioration?

Dear Philippe and other 41 owners. I have finally got around to servicing our cockpit bilge pump and understand exactly the problem described. I am very reluctant to cut an access hatch and having looked at today think it impossible that the pump was accessed past the steering quadrant - certainly not an option fixing a problem at sea. But the pump must have been serviced in the last 40 years, how? The only possible way I can see is to dismantle the bulkhead at the aft end of the port bunk in the aft cabin. Still not realistic in an emergency, perhaps cutting an access hatch in the bulkhead may work? But still doesn't explain how it has been done so far, there must be another way? Much appreciate any advice from someone who has solved this puzzle. Andrew "Scotch Bonnet" 41/039 |

Dear Andrew You could also consider cutting loose the panel where the cockpit pump is mounted, and reattach it with a flange covering the joint, or make a new overlapping panel for the pump. The connection should have easily opened fasteners which can not drop out. The panel could be hinged, provided the hoses allow the pump to swing out into the cockpit.
I wonder if during the build there was access through the helmsman's seat, but this route was then closed by some additional partition.
Kind regards
Lars
