"On the face of it the new Volvo Ocean 65 is another high performance, beamy, angular offshore racer," he writes for the official Volvo Ocean Race website.
"But there is a great deal more to her than just this, particularly behind the scenes and under her skin."
Sheahan - who recently gave the keynote speech at this year's ICRA Conference - notes the boat's improved safety features, including better shelter for crew.
That has the added effect of optimum shelter for interviews, which should make the 2014-15 edition of the round-the-world yacht race an even more direct experience for fans following their favourite boat's fortunes.
Meanwhile, Sheahan is particularly impressed with the carbon fibre hull, which achieves "a robust structure without piling on the pounds" and makes the VOR 65 "a tougher beast all round".
