For Heavier Sailors in Order

DK-17
The Tool
Geltek Flyer 2
Bim XJ or MM's A3

The tool though is a production boat made for heavier sailors. The DK17 is more of a one off design that evidently can be built for you. The A3 seems to be less likely for heavier sailors. I took a close look at the DK17 during the NA's in Bristol and was very impressed with the quality and workmanship.
