Dear Brian, I hope you are well. Thank you for your comments.
I would like to refer to our esteemed member RT Firefly quotes*: «*EVERYTHING rolls at sea, cats included...*under various conditions and experience … Oh, and don't let anyone talk you into a vessel that does not pick you. (You really don't pick the vessel-trust me)...I know that some people have ventured successfully into open waters with the boat but so have rafts and many others that should not....»
I also refer to Ted Gozzard statements to Jim Elliot our Pilgrim 40 past owner, that to build a Pilgrim 40 with todays material and labor, he would have to retail it over a million dollar... It would be fair to say that custom construction project would cost at the minimum 500K.
This being said, as mentionned by Ed, all Pilgrim 40 (may be except "PAPILLON"*with stabilizers) as any sail and trawler boats do roll underway, I might add also the rolling motions abeam (unless you cut the wake) after a slow or fast pass from a imprudent cruising captain and at anchorage with any wake created by disrespectful skipper at the helm.
I wanted to consider flopper stoppers at anchorage but made the choice not to complicate my life as to reduce the actions in doing manoeuvers.
If you can find the appropriate place in the vessel, maybe a gyroscope (designed to eliminate only 95% of boat roll) ( and consuming AC or DC power) could work well.
At the same time, I estimate this project opportunity cost for over (32,340.00$usd + taxes + Installation which is not not included).
Here are the specifications for the gyroscope*:
Rated Speed 10,700 RPM
Angular Momentum 5,000 N-M-S at Rated RPM
Anti-Rolling Torque 13,089 N-M at Rated RPM
Spool-up Time to Rated RPM 50 minutes (10,700 RPM)
Spool-up Time to Stabilization 35 minutes (9,035 RPM)
Spool-up Power AC Motor 2000 Watts
Max DC Control 180 Watts
Operating Power AC Motor (sea state dependent): 1500-2000 Watts
DC Control: 180 Watts AC
Input Voltage: 110-230 VAC (+/- 10%), 50/60 Hz, Single Phase
DC Input Voltage: 12 VDC @ 15 Amps
Sea Water Supply 30 LPM (8 GPM)
maximum to Heat Exchanger 15 LPM (4 GPM)
minimum Ambient Air Temperature 0°-60° C (32°-140° F)
Weight 358 kg (790 lbs) bolt-in installation
Envelope Dimensions 30.1 L x 29.8 W x 24.7 H (inches)
I almost forgot... The Noise Output At full operating RPM, steady state noise measured in the factory at a 1 meter distance measures 70-72 dBC and the sound levels may be higher during spool-up!.
From my 7th boating season and over 4000 statute miles cruising experience our Pilgrim 40 is still a great inland/coastal 20 miles vessel. It is a slow boat to enjoy cruising and enjoy the sceneries.
My opinion is if you need an open sea boat with hard chine, I would suggest to forget the Pilgrim 40 and consider a Downeaster or Passage maker type vessel equipped with a gyroscope that fits your cruising needs.
