Mark has a couple of slick designs, with another he is working on...

I have admired Mark's designs for some time... they hold several attractions to me, including:

• Roomy (although the beam is quite narrow)
• Designed for the amateur builder
• Incredibly inexpensive plans (and available in metric and English)
  
• Shallow draft
• Outboard powered

A few cons (to me):

• Not offshore boats
• High windage/lots of glass
• Wood designs only - expects to be
  
• Narrow beam (can be a pro, also)

They successfully built the boat and made the Great Loop cruise.
