Not that it has ever happened to me or my crew

(twice during NACR races) .......(( but those are another 'story'))
The DS is pretty stable, but if you go to one side and try to pull another out of the water, a capsize is possible. If the swimmer is strong, the transom area is the easiest to hoist ones self back aboard. If the swimmer needs assistance, I tie a foot loop in the end of the mainsheet with a bowline. The swimmer can then put a foot into the loop, the helper can then pull out the slack and hold, as the swimmer steps up using the loop for a step. If another step is necessary, the swimmer can hold their position, relax the leg with the loop, helper pulls in slack again, and them the swimmer can step up higher. Usually the second step is enough the get them aboard. Another solution, might be to have a premade set of loop steps (use old main sheet perhaps).
hope this helps phill
