Yes, the 3D is the one I mentioned in post 5 - sigh - was in stock at Seamark Nunn.
Well I have a Vivacity 20 and manage fine with the 2.3m WavEco with transom. It fits either in the v berth or on deck, or this weekend I towed it with negligible loss of speed.
LustyD, I think your problem is 4 stroke engines, not round tails; I wouldn't have a 4 stroke main or tender engine as the weight is a daft embuggerance in both cases, and extra weight like this will kill performance of a 20-22' boat.
I always found that towing made massive difference to speed unless off-the-wind in good breeze. I have a Lodestar 220UL (ultra-lightweight), but gave up trying to get it into the forecabin of my 20 footer, which is basically why I gave up on proper tenders as I really couldn't get much smaller.
My Zodiac roundtail with large tubes was happy with a 4-5 hp 2-stroke hung on it, I don't think I'd try that on the smaller tube Seago dinghy but it's happy with the light Mariner 2hp 2 stroke; I don't think there's much difference with buoyancy comparing roundtail to solid transom, it's the rigidity of the mount.
How anyone uses a small 4 stroke engine on a tender on & off any size boat beats me, asking for back trouble and a dunking unless one can fix up a davit of some kind; I bet your Vivacity would show her thanks if you sourced a Mariner / Yamaha 2 2 stroke !

Our good friends with a Jeanueau Sun 2000 used either a 230 RT or a Bombard ax2 which stored rolled up across the back of the cockpit underneath the tiller. so I know it can be sorted with a small tender.
