Generating electricity with a hydroturbine under power will clearly be a no-gainer due to the laws of thermodynamics (i.e. the parts that allow no perpetual motion machine). However, for a motor-powered vessel, one thing you might consider in this discussion is anchoring or mooring during tidal...

Comments to DaveInRI from RobInWA regarding electric vs. gas outboards for dinghies, etc. for different platforms as a CD22 tender. I have 0.7 and 1.7 HP Cruise-n-Carry 2-cycle outboards. These are very portable, lightweight (12 and 18 lb), extremely noisy, and currently unavailable in the US. I...

Awesome! I would suggest this book, and there are others for other states...

Seems to me they might be about the same actual miles, but US20 to US2 to Spokane is probably quicker. I'd still take smaller roads through Bridgeport and Grand Coulee to cut corners off the drive, but I'm towing a CD22, not a CD25. I can't judge personally, though I've driven most of the roads...

Good idea for the mini...it may eventually become something you use regularly as it has with me. Being truly isolated may be fun, but having weather forecasts, letting the significant other(s) know you are OK, and being able to make an informational or emergency phone call (rather than summon an...

Colby; I boated south from Prince Rupert last August, a trip to help a friend that found he had a deep tumor on the way to Alaska from Anderson Island that required surgery. They were able to moor in PR and fly back for his surgery. Then, they needed to bring their boat back. He was told not to...

Simple matter of math. My ICECO 45 qt will draw 3.7A at 24VDC when running, watt equivalent to 7.5A at 12VDC. That would mean about 13 hours for a 100AH 12VDC battery running from full to zero, though the freezer doesn't run all of the time except when its very hot and set at the lowest setting...

Great idea for the steel scrub pads...I'd used aluminum foil, but they seem to chew through it anyway.

Should I be happy that my tabs are hydraulic? It sounds like these are having a high rate of failure.

I built and maintained a web site for international discussions about "Forest Soils" sourced at the U Washington for decades, so I am somewhat familiar with what is involved in creating and managing sites. That sprang from the privilege (?) of seeing what could potentially be done with networked...

This is my first attempt at a movie on this site. I was taking the Black Ball Ferry from Victoria, BC to Port Angeles, WA. Hopefully, this link to Youtube of a movie I made of the electric harbor boats will post OK. Try clicking the link below... Electric Harbor tour boats in Victoria...

Bob; You are another class of waterman than me, obviously, in both skill, experience, and patience. I worked 35 years with another forestry professor that had a 57 ft, 15.5 ft beam 100+-y-old wood sailboat (Mary Hillyer) he bought as a derelict and restored beautifully. He had re-rigged the...

Speaking of sailing...just peeked out my window and saw this in the outer part of Oro Bay. Gone in a few minutes. Greenland-style paddles too! These guys were really moving, maybe getting ready for the WA360 or Racd-to-Alaska. Anyone ever deploy a sail on a C-Dory? It could work today, as long...

That is so cool. If you put a level camperback over the CD22 cockpit, that could probably double the area. I fixed one 175 watt semi-rigid panels on the CD22 over the roof, and one over the camperback, with bungies. The one over the roof is quite stable, and I bring the one over the camperback...

I was warned to never start my motor with all of the electronics running. I just switched it off and then back on when I started the motor, which was somewhat of a hassle. My initial change, back when Li was crazy expensive, was one 100 AH 12 VDC with a DC/DC charger between the starter and...
