The radial and 4.7 use the same hull, boats, boom and top section, control lines, fitting etc. The only differences is they use different sails, sail numbers and bottom section. The 4.7 sail area is approximately 4.7 square metres and the radial is approximately 5.7 square metres, so the bottom sections are different in length as a result and the 4.7 bottom section has a permanent bend to obtain a reasonable sail shape. A lot of the people sailing 4.7's only purchase a radial sail and bottom section when they decide to move up to sailing a radial.

What is the differnce of 4.7 and radial and do they use the same hull ?

Possibly. What help do you require?
