That's the way to do it. I'd add that if the boat is moving forward, it's damn near impossible to pull yourself up on an infusion or cap from the front beam, whereas its actually not hard to do it from the back beam, even when it is moving. Getting on from the back also allows some improvised water based steering. As the boats usually have nearly neutral helm (i.e. they have been known to sail away quite a distance on their own...) one good idea is adding safety line under the tramp from the front beam to the back to hang onto when going to the back of the boat.
