I think it would be nice to be able to have some storage space in frontt of the forward crossbar but i think it would increase the difficulty in going downwind, espically in high wind or swells. when we sail trips with our hobies we not only cram 3-4 people on a sixteen but all of their personal items for four days. we usually just lash the stuff to the mast, the only problems we usually have are with the jib sheets getting around the mound of drybags, on the positive side they make a great lounging area for 2-3 people to work on their sunburns. it is also essential that your dry bags are closed securley, wet clothes make for a miserable three or four days. depending on what kind of sailing you are planning on doing this may be a more practical alternative.
The pessimist complains about the wind, the optimist expects it to change, the realist adjusts the sails.
