I have read your posts in a few other areas and have noticed that you are planning on a Lagoon 440
or new 450. I know you like "fast cars", but I would reconsider how much weight you're putting on a 44' cat more than worrying about having it stolen. The lagoon 440
, is not a particularly fast boat to begin with and with the type of weight you seem to be planning to add, you'll be looking at monohull
sterns most of the time. I'd go light and go fast, 25 HP on a dinghy is plenty and still allows you to remove it if necessary. 280kg is Lagoon's max suggested weight on the davits, but planning on cruising the world with anywhere near that much weight on the stern seems risky. Please see earlier posted replies "Lagoon quote the same restriction for the 420 and we completed an Atlantic Circuit with approximately 200kg strapped to our davits. I wouldn't want to sail with anything heavier. The length of our RIB
(4.2m/14ft) was not a problem on the 420 (more of a problem on the 440, I think), but the weight was a concern, especially in heavy seas.
When on a passage
, we also demounted the outboard (not easy, even with a 15hp outboard - 40hp would be almost impossible) and helped to support the davits with lines to the top of the bimini
posts. In fact, on a passage
we trussed the RIB
up so it didn't move at all in any direction. You sure don't want 360kg swinging around at the stern.
I have seen two 440s with twisted davits, so the danger
of damaging them with 360kg hanging off them is considerable.
My view is that sailing any kind of passage with 360kg hanging off the stern is asking for trouble. For a start, you want to minimise weight at the stern for safety
and performance reason, so I think you'd be crazy. In calm conditions (and I mean calm), you would probably get away with it as a one-off.
