John,

Thanks! The davits were there when you were on board - maybe you were so scared that you didn't notice! We're still looking forward to laying alongside Serendipity some where soon!

IMHO it is not the width of the beam, but the width of the transom that is the critical dimension. I would be seriously concerned in bad weather if the bow/stern of the tender is sticking out significantly and I was beating to windward. The other critical dimensions are buoancy in the stern and height above waterline - significant when running before the wind in high seas.

Thanks for that Talbot... the height in particular is a good point I feel.... my davits are high enough, that if I can crank the tender up as high as possible, the keel of the tender will be 3' off the water, so I think i've some room for maneouvre.... I guess if we were on a very long passage, we may well stow the tender on the foredeck anyway rather than do extended passage making with it hung off the stern...

3 ft sounds good, but is so dependent on the bouyancy that it is impossible to give a straight yes/no answer. The only way is to suck and see with the weight applied in the right place. You also have to consider what would be the result if the tender had got a lot of extra water into it. (i.e. forgotten to take the bungs out - or just poor design. My major criticism of the Zodiac fast rider was an inability to get water out of the bottom of the boat, and its 10-15 gallons of water that could accumulate there in a heavy downpour

I've bought a little 8' pram that is nearly completed off eBay for £83!







A few hours work should see her on the water, and then a few more hours should see her sailing (all the sailing bits for a Gaff rig are included)

At 8' its a bit smaller than I originally planned, but I figured that 8' is big enough... and at £83 it was a bit of a bargain.... much less than the cost of the materials, and most of the hard work done!

Thanks for all your advice everyone...

You saw ours in Scotland a couple of weeks ago - 2.6 rib on a 30' boat. Horrified? - too late - yours is paid for! Only concern is only 3' between it and the water - under way the mothership will squat, and with a big sea you might get a little "extra lift"... We've had it happen on Sahona.
