Hi Guys and Gals,I need a bit of help please!I am looking to purchase either a 461, a 473 or a 50 (jury's out on which one!) to ship back to Australia piggy backing on a container vessel.They need some dimensions I cannot supply at the moment to be able to get them to quote me for the trip."Height from bottom of keel to highest point excluding mast" and "Mast height" are the most important as most other info is available on the net.Would appreciatte any info anyone could pass on about these models.Many thanksBen
