Posts: 302 Daytona Beach Florida | Can anyone tell me it Marstrom made any design/construction changes in the hulls/blades/rudders between a 1990 tornado and a 2001 tornado?

Hulls are all from the same mould. All are Nomex Honeycomb core. No known changes to internal structure or layups. Post 2001 boats have spin-pole bridle fittings already in the bow tips.

Posts: 1,200 Vancouver, BC | The Marstrom hull cross section is different than other builds. Most noticably around the aft section of the hull...Marstrom is quite rounded where others (like SailCraft) are flatter or angular. There are small variations permitted from the official section templates...but these don't give much performance advantage across all sailing conditions.

Posts: 1,203 uk | It was sailcraft that did most of the tweaking of hull shapes
Some sailors were able to recognize a 'Front fatty' or a 'Middle fatty' at a distance

Hull shapes were pretty consistent up until they went T-U in the early 90's. There was only one set of hull/deck moulds present when the company folded up...I know b/c we took in & stored all the left over equipement/stock for the final owner (which he never came back to claim to this day).
