Two part tender

[samwise]

I seem to recall seeing a neat solution to the problem of stowing a hard tender on the foredeck, which involved having the boat in two halves, nesting inside each other when stowed. I am interested to know how they might have solved the problem of keeping the two halves together and keeping the water out when being rowed. I guess there may be some plans somewhere.

the usual method is to have bulkheads at the 'open' end of each part, so in effect you have two boats, which then bolt together by some means. unfortunately I don't know where one could get plans, althogh would be very interested if someone else does!

Ah ha the dreaded Pack-A-Boat, tobble's description of how they went together is correct In my early sailing days we atempted to use one of these fine craft as a tender (11ft version) but it had a nasty tendancy to try and overtake us and would try to impale itself on the transom. As the bow section was about 7ft we tried using just the bow section but in this mode was horribly tender and if there was a even the slight chop rower and passenger had to row (carefully!)otherwise there was a fair chance of sinking before you reached the boat
Needless to say there was a big sticker on the "transom" of the bow section warning not to use the boat in two halves but it had to be tried!!!!

I built one some years ago from plans in Yachting World. It had a cathedral hull and was fine after working out the best way to join front and back together. Yachting World might still have archival material available.

There are a few other designs available on-line of nesting dinghies as well as folding dinghies.

On the Spindrift models, five bolts/wingnuts hold the 2 halves together and without gaskets it lets in less than a cup of water per hour. Otherwise the more sophisticated joint is http://www.pbase.com/sailrosita/expedition_dinghy

There was a link here a few months ago on this topic. Keywords ' nesting dinghy' etc.

I made my 9 foot spindrift fit onto the deck of my 26' yacht, by making the rear a canoe stern rather than a wide stern. I don't know how to add a photo here but here's a link http://www.boatdesign.net/forums/showthread.php?p=147769
