the wind. Trimarans are popular with many sailors for their stability, but if capsized (for example by a rogue wave), they are virtually impossible to right, though crews have lived for months with a boat in the inverted position and ultimately survived. To improve the safety of the boat Crowhurst had planned to add an inflatable buoyancy bag on the top of the mast to prevent capsizing; the bag would be activated by water sensors on the hull designed to detect an impending capsize. This innovation would hold the mast horizontal on the surface of the water, and a clever arrangement of pumps would allow him to flood the uppermost outer hull, which would (in conjunction with wave action) pull the boat upright. His scheme was to prove these devices by sailing round the world with them, then go into business manufacturing the system. However, Crowhurst had a very short time in which to build and equip his boat while securing financing and sponsors for the race. In the end, all of his safety devices were left uncompleted; he planned to complete them while under way. Also, many of his spares and supplies were left behind in the confusion of the final preparations. To top all this, Crowhurst had never sailed on a trimaran before taking delivery of his boat several weeks before the beginning of the race. On 13 October an experienced sailor, Lieutenant Commander Peter Eden, volunteered to accompany Crowhurst on his last leg from Cowes to Teignmouth. Crowhurst had fallen into the water several times while in Cowes, and as he and Eden climbed aboard Teignmouth Electron, he once again ended up in the water after slipping on the outboard bracket on the stern of the rubber dinghy. Eden's description of his two days with Crowhurst provides the most expert independent assessment available for both boat and sailor before the start of the race. He recalls that the trimaran sailed immensely swiftly, but could get no closer to the wind than 60 degrees. The speed often reached 12 knots, but the vibrations encountered caused the screws on the Hasler self-steering gear to come loose. Eden said, "We had to keep leaning over the counter to do up the screws. It was a tricky and time consuming business. I told Crowhurst he should get the fixings welded if he wanted it to survive a longer trip!" Eden also
