Here's the secret to how it goes together. Six 3/8" bolts, fender washers, wing nuts. They made us a nifty removable bow seat with a little storage under. Dave assured us that the bow section would go straight to the bottom if detached. We gave up the bow flotation compartment in return for nesting. There's plenty of flotation aft. If we can find some warm water, we'll stage a capsize and see if we can get the water out.
We haven't truly turned it into a nesting dinghy yet. The bow section is almost a pyramid in outside dimensions. We can fit the bow section underneath, but if we don't, there's room to fully open the forward hatch underneath the dinghy without any interference. I did a lot of idea testing when the dinghy was parked at the house.
Stern lashings are reasonably secure. I'll need to figure out some kind of chock arrangement for the stern. One goal is not to drill more holes into the deck! None of this will stand up to green water over the bow. Fortunately, we have not encountered such conditions even when running down the Pacific coast. We have never buried the bow completely.
Here's the bow lashing photo again. Each eye nut will have its own dedicated lashing line eye spliced on. Trying to keep it simple and foolproof.
