Limited by size, length and/or cost...?
Jim, don't paint yourselves into a corner where you equate length with size, nor with coastal sailing suitability. Are you mentioning 30' because of a slip limitation, because you imagine a specific displacement target, and/or thinking of cost?Boats of similar lengths can be all over the map on meeting other criteria for a good coastal cruising/liveaboard boat. To mention two extremes, Eric & Susan Hiscock's WANDERER III was immense by contemporary standards and built extremely strongly to boot, yet was in the 30' size range you mention. The Pardey's current boat, as everyone knows, is also huge (re: displacement) tho' "only" 30' long.Determine what true limits you have (e.g. cost, slipage, and the draft requirement you already mentioned), and then begin looking for suitable boats that offer you the most (in displacement, condition, equipment relevant to your needs, layout) within your price range. Divorce yourselves from thinking a specific length and see where that leads you.You don't mention your location, which can have a huge effect on the types of used boats available to you. E.g.1. Downeaster 32 (mostly a West Coast boat)2. Tartan 34 (the older and also the newer 33' versions, predominantly on the East Coast3. Pearson 323 (Al's rec is a good one; East and also Gulf Coast)4. Hallberg-Rassy 35 (4.25 designed draft; Pac NW and East Coast)I'm sure there are 30 or 40 designs in sufficient production numbers to warrant investigation. Good hunting!Jack
