After sheeting out the sails and righting the boat after a capsize, the sails may not be in "heaved-to" configuration and the boat may be trying to sail forward. It is good to know that that situation may make climbing the ladder difficult, as you observed. -- With the ladder in hand but with the tiller and sheets still out of reach, was pushing/pulling the rudder blade an option to turn the boat more into the wind? Similarly, if the mizzen sheet was within reach, sheeting it in could help turn into the wind and slow the boat. -- I imagine if you just happened to have a drogue (parachute/basket/bucket) on a 10' line neatly folded and mounted on the transom for emergency use, deploying that would slow the boat.

Well done, Amos!

Yes. The sliding panels can slide out of the tracks when the "garage top" is removed. The garage top is held in place by a set of port and starboard screws that are thru-bolted into permanently placed rivnuts.

Yes. It is unnecessary, but there is also fiberglass cloth helping to hold the aluminum onto the plywood panel. It is the edge of bare aluminum that slides in the track. The aluminum is epoxied to the underside of the sliding panel. The aluminum edge slides in a track. The track is a groove cut into epoxy that was thickened with graphite powder: the idea being that the graphite might reduce friction of the aluminum sliding in the track. I do not know if / how much the graphite helps. It would be interesting to measure coefficients of friction of aluminum sliding on epoxy-with-graphite vs epoxy-without-graphite. Oh, it appears that has already been studied: just google "friction between aluminum and epoxy that was thickened with graphite" for that information.

Amos, here's a few views that may help. The last pic is a look up into the CB well at the inflow/outflow pipe. The next to last pic shows my attempt to isolate pump vibrations from the bulkhead. There are 3 filters in this system (shown as circles in the diagram).

Yes, I too am unable to read posts due to the "something went wrong" server/configuration error

Steve, So glad to hear that news as it will be great to hear more about your experiences with quiet motoring! I went with an ePropulsion motor too... (boat ready for painting, still need to build masts and install rigging).

This is a related tool review:

"LiFePO4 cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. They can also withstand freezing cold, scorching heat, and rough terrain. When subjected to hazardous events such as collision or short-circuiting, they won’t explode or catch fire. Also, LiFePO4 batteries are non-toxic, non-contaminating and contain no rare earth metals and no cobalt or nickel, making them an environmentally friendly choice." -- relionbattery.com Regarding the meaning of "incombustible", it's reasonable to follow the advice of Will Prowse. He says a LiFePO4 battery is like metal box full of wood. It's stable and is not going to spontaneously combust or explode. Of course, if the entire boat is already a bonfire, then you could make it burn. Caveat emptor: when purchased from a reputable dealer.

Andy, we've had it in the water once at the 2024 B&B Mess-about; it seemed very good to me. For a more experienced comment, I suggest this one .... https://messing-about.com/forums/topic/16822-electric-or-gas-motor-for-a-core-sound-17-mark-3/#comment-120313

Brilliant, Steve. Copy that!

Cool! (Pun intended) Thanks for sharing, Steve! Is the height of your mizzen tabernacle as specified in the 20.3 plans ??? (I was thinking of reducing the height of mine by an inch or two. Maybe.)
