Lars,
The feature in The Yacht Report #69 includes a first-hand report on the sea trials and first months of operation, made by Steve Lloyd, the Chief Engineer. I can send you a copy by e-mail, if you wish.
Also, I can prepare for you a power plant spec (with equipment dimensions and weights), if you want to fit it into your GA. Just give me some more details on the power requirements for the Polara Explorer.
Nice design, by the way. The non-bulbous bow tells me she is ice-classed. What class ?
Regards,
