Doing research on which dinghy to buy lead to a lot of confusion. The choice of motor also was also not a clear cut decision. I wanted a dinghy made of hypalon, so that it would survive strong sun. Beyond that, there are arguments for buying the biggest dinghy you can fit on the boat, or buying a RIB which has a rigid fiberglass floor but that doesn't roll up, or buying a wood floor, or not buying a motor but rather buying a dinghy you can row more easily, or buying a large motor that will speed the dinghy along, or buying a small motor which is light and fuel efficient.
In the end, I bought an Achilles LSI-260. It has a high pressure inflatable floor, which means I can deflate the thing and roll it up into the size of a duffle bag. This will be useful for offshore passages where I can store it below in the cabin. Its 8' 6" and weights 66 lbs. The motor is a Tohatsu 3.5 hp 4 stroke. It weights 41 lbs.
I bought it at Ballard Inflatable Boats, in Ballard. I always prefer to spend my money locally, and they gave me good service and advice. They are recommended. They will also talk you through the technique for affixing the registration letters/numbers onto the dinghy, which was useful.
Here's the dinghy in Echo Bay on Sucia Island. I've been in this bay three times, but this is the first time I've been to shore. The Island is wonderful, there is a lot of good walking, lots of camping sites, fire pits. Being able to get to shore totally changed the visit this time.
The dinghy is also a perfect fit for Luckness. The dinghy fits perfectly in front of the mast and behind the staysail stay.
Getting the dinghy up on deck is easily done using one of the spare halyards, the spinnaker halyard works well. Attach the halyard, winch it up using one of the winches at the mast, flip it over and tie it down. The side decks are free so I can still walk up and down both sides of the boat stern to bow.
After my visit to shore in Echo Bay I was returning to the boat in perfectly calm water. I went out toward the mouth of the bay where there were no boats around and wanted to see how fast I could get the dinghy going. I found that in perfectly calm water, with one person aboard, if I opened the engine up to wide-open-throttle, then shifted my weight forward as much as possible I could just get the dinghy up out of the hole it was in and onto plane. Once the dinghy was planing it hit 10.7 knots! That yielded big wide grins! If there are any ripples or waves on the water at all, it won't plane. But it gets around pretty well, going 5 to 6 knots. Its a rockin little tender.
