40Kg on the pushpit too much?

   Hi All,
Any experiences?

40Kg outboard on the pushpit, feels solid enough at the dock but what about at sea?
Cheers.

	Ian - in my opinion and experience that's a seriously bad idea. The fittings are not designed to take such a weight and, although the fit may feel stable to the touch it will be subject to constant stress as the vessel moves to the sea - even in a marina. Over time, even alongside, you'll see increasing growth of cracks around the stanchion bases. This will be magnified hugely when actually at sea especially when things get bouncy. No way you can conclude that the fitting is up to the job without specialist kit; just because it feels ok at rest doesn't make it so. You'd need to massively reinforce the pushpit where it connects to the hull; Hanse's are solid where they need to be but they simply aren't built like that. I suspect that few marques would take such a load without modification. Even if you did this there's the effects at sea with so much weight right at the back where you don't want it to be, especially downwind; the stern will dig in further and cause drag. Especially when combined with weight at the bow, perhaps a decent size anchor and chain, your boat will hobby-horse a lot more in waves and you'll struggle to make progress. I sail offshore quite a bit so I bring as much weight as possible midships and low down where able. Of course, everything in sailing is a compromise and if you need such a powerful outboard then its got to go somewhere, but it would interesting to know why you consider you need such a beast. Such an engine could even propel your yacht.....!

	I have the same Lalizas outboard bracket and it works with 34kg 15hp 2-stroke. This year I will change to a new/better bracket with wood and stainless

	I am mounting the sameYamaha 9.9 HP 4 Stroke outboard at the same position on my H418. It should be ok. For assurance here is a H458 with a Tohatsue at 52 Kg mounted on the pushpit. I would think the Hanse pushpit should be able to handle 40kg as there are many Hanses with liferrafts mounted on their pushpits and many of these are at least 40 kg if not more. I haven’t heard of any reported structural problem with mounting this kind of weight on the push pits. Good luck.

	Ah well, everyone has their own views and quite right too. However, as an offshore sailor the photo above concerns me, as if the stern got clobbered by a wave this might well cause serious damage as that engine goes flying into the cockpit. Part of my 'lumpy seas' routine is to move my small 3.5hp motor into the lazarette and only mount it on the pushpit when day cruising. If all you're doing is short hops along the coast then the equation may well be different for you but you don't need a degree in physics to work out the stresses such extreme weight as above is placing on the fittings; same goes for heavy liferafts. Such weight unquestionably affects the sailing qualities of the vessel and contradicts the calculations behind the yacht's design. Of course, the nice thing is that we can do whatever we like with our own boats. There's a compromise between convenience and good seamanship which will vary according to our own personal preferences and the conditions that we sail in. For me, however, 'just because you could doesn't mean that you should'.

	Thanks for all the comments. Why 9.9? Same reason we drive a 200-BHP Mini Cooper S … it’s a lot of fun! More seriously, our crusing area has 14m tides so not unusual to see log spinning 4-kts while at anchor; we need tender that powers against that with ease. Never had concern by our 40Kg liferaft hanging on port rail; feels much more solid than 40Kg outboard on starboard rail. You guys have made me think about improving this set-up. Many thanks.

	I'm sure you've sorted this by now, but for what it's worth, we put our 15hp four stroke, over 55kg, on the pushpit and have done so for over 10,000 offshore miles. No problems, no cracks, nothing bent, never felt like it was not appropriate to me or the shipwright who customised the bracket to fit the rail.

	do the same with my Tohatsu 9.9 85lb=40kg exactly as pictured on 458 above, for the record all stanchions are backed by thick aluminum plates, crack talk is fantasy

	Marsella - on this site people ask questions and others then offer opinions based on their own experiences, so we can all learn. If you have had different experiences then I would respect any opinion you might have based on that - but in turn please respect those of others. So much depends on the actual conditions you cruise in; you might well do many tens of thousands of miles and be lucky (or have consistently planned well!) but you might have been in some conditions which tested your boat very severely. Part of the refit currently underway is to beef up the backings of all through-deck structures as, given my own experience, I don't consider them strong enough. Faced with a nasty sea state, I most certainly would not want to have such a weight influencing the balance of my boat or potentially compromising its structure where there is any risk of being struck by a large wave - but I appreciate others may have found differently. The original questioner received a balanced response and is probably better informed to make a judgement based on his own boat and own likely sailing grounds; that's the good thing about this forum.

	So, 40kg not been too much for pushpit guard rail ... however that old Lilzas plastic bracket was looking a bit wonky by end of last season. New one made at cockpit table from two pieces of 25mm thick teak drilled through for the rail, Sikaflexed and bolted together. Hopefully this will last!
