Peter, I've been wanting to comment on your thread on Tugnuts but don't have an account there...
Regarding storage, I can understand your desires to be closer to home, possibly saving some $, including extra cost of a camperback. But the main benefit I see of Twin Bridges over outdoor racks like Edmonds, is not just protection from rain and keeping the cockpit clean. More importantly, it's out of the sun in a heated shed. Less worries about winterization, frozen water pipes (and you'll have more of those in the Ranger!), UV damage to plastic panels / canvas enclosures, gelcoat fading (especially dark colored gelcoat like a Ranger), high winds, and seagull poop.
I've watched a lot of boats "rot" away sitting on those racks at Edmonds over the years. For all those reasons and many more (like proximity to my preferred boating territory), any extra cost of TB over Edmonds is easily justifiable for me, and Edmonds is only20 minutes from me. I love my boats as much as you have with C-Dancer, and couldn't see myself putting a boat on the open racks at Edmonds...would much rather give up the convenience and have it on a trailer at home where I can keep it covered with a custom tarp and keep a close watch on it. Are you buying a trailer with your new boat?
Also to consider, would you have onsite Yamaha service available at Edmonds like you would at Twin Bridges? Or will you be doing all your own maintenance?
Obviously I'm a big fan of TB. And I have you to thank for that!
Congrats again, looking forward to seeing the new boat at next year's FHCBGT if not sooner!
