It has taken a long time to make the decision but I have decided to sell the Nimbus 340 power boat I bought with my wife. She sadly died and I cant handle it on my own and miss flappy things up above but want some power boat comfort. Hence, I am looking at LM32 not that there are many about. I am from near Southampton and there is one in Gosport but under current restrictions cant get to see her yet. However, some questions please: 1) What is the air height, for bridge clearance in Holland. 2) Do the holding tanks always have a Y valve with deck pumpout. 3) Anyone fitted solar cells, looks possible to put two, one each side on the cabin top just aft of the mast?
4) Does the cable steering have a wheel disconnect to remove that friction when using the tiller.
5) Any views on the life of a 3 cylinder Bukh engine as the one I am looking at has done 4000 hours.
I have asked some of these, and many other, points of the broker but I did not get an answer. I guess he does not know.
I've never been on a 32, so can't help with most of your specific queries, but hopefully an LM32 owner will be along soon to advise.
For the air draft I have scaled off the drawing in an LM catalogue, and from this it appears that the height of the top of the mast above the water line is just under 44' (c13.4m). You'd probably need to add about a metre or so above this for VHF aerial, nav lights, windspeed transducer, etc., so say about 47' 6" (c14.5m). I can offer no guarantees, though, so on your head be it!
With the mast down, using the same method suggests an air-draft (over the wheelhouse roof) of about 7' 6" (c2.3m). Again, I cannot be certain of these figures.
You have probably seen there are also currently a couple of LM32s for sale in Scotland, one at Largs and another at Lossiemouth. (The latter, especially, rather out of the way, but it would be quite an adventure bringing it home!)
I hope you can find an LM to suit you, and don't have to wait for too long to do so.
Thanks for that, the last boat we had in Holland was a Dehler 36 CWS with an air height of 18m, sometimes interesting. In fact my wifes plan with the Nimbus was to visit the bits in Holland we could not go with a mast! I had seen the two in Scotland but it is a bit of a trek, especially back. The one in Gosport has the spec I want by chance, just a bit twitchy about 4000 hours on the engine. I do have a motorhome so visiting Scotland is not a problem. The longest delivery I did was Milford Haven to Portsmouth, as I get older I get more careful about my physical ability. I get my OBE at the end of the year, Over Bloody Eighty.

Hello, and I hope you find an LM32 as delightful a boat as we find ours.
1) - I agree with Sula that the mast height above waterline would be very near 44+ feet.
2) - I don't know if all LM32's have a Y valve to empty the black water holding tank either directly into the sea or via a deck pump-out, but ours does.
3) - As the efficiency of a solar panel is so intrinsically linked to its angle to the sun; I attach the top of my 100w flexible solar panel to the top line of my lifelines via snap clips, and built two arms that are affixed to the bottom corners of the panel with their other ends sliding along the mid height lifeline. In this manner I can adjust the angle of the panel to typically be perpendicular to the sun. I have 25' cables and at this time I simply run these cables up a hatch, and can thus attach and orient the panel to the boat at whatever point and at whatever angle best suits the position of the sun at the time I put it out. I then move the panel about as necessary when I wish to maximize charging capability. I do also lay it flat on the fore deck on occasion. The 'hang it anywhere' approach avoids the shadows of the jib, boom, shrouds etc. falling onto the panel. While the shadows of the shrouds doesn't seem like much, I have read that lineal shadows across several cells significantly affect the output of the panel, and I have noted this to be true when monitoring my panels output.
I have been thinking about adding some hard wired quick connect points to plug the panel cables into, thus avoiding cables running through the salon and up a hatch, but I haven't got around to doing that yet. I would place one on each side of the pilothouse, up under the overhang of the pilothouse roof,
As to your proposed location: I sometimes find it necessary to stand near the mast base to work the whisker pole, etc. so I would be cautious about affixing a panel to the deck at the base of the mast.
For a short while I considered affixing solar panels to the pilothouse roof, and found various panels of an appropriate size to achieve this, but as I find myself on the pilothouse roof when furling and unfurling the mainsail, I rejected this approach and instead went with the outboard lifeline attachment described above.
I have also been considering designing an inverted L shaped pole that I could mount the panel on, such that the panel could still be optimally oriented toward the sun, and this pole would install on or through the aft deck.
4) Yes, there is a disconnect handle at the wheel, to separate the wheel from the tiller.
5) Our Bukh DV36 has ~2300 hours and runs very well without any oil consumption or other apparent fault. I don't think that 4,000 hours is a lot, but I have no first hand knowledge of the expected life of a Bukh engine. As they were the only approved SOLAS engine for such a long time ... that must say something about their reliability, but Bukh engines appear to be very rare on the west coast of Canada. I arranged for a mechanic to give my engine a going over before I completed the purchase of my boat. He checked the compression and a few other attributes, and gave me a short written report on the engine. You may wish to consider doing same. I understand that diesels can last significantly longer than petrol engines, and I have ~300,000 km on my diesel VW Jetta so far without any need for mechanical intervention. Always keeping my fingers crossed though!
Thank you very much for all the points you have made, I asked about the solar panel position as wondered if one ever needed to stand there. If I do end up buying her I might take the liberty of coming back if OK? One point that has come up is a recent survey says the holding tank is not more and the broker insists it is there. I wonder if the bow thruster goes through it. Find out the truth when I can finally get there . I can do things to my present boat as it is tied to my own jetty at the end of the little garden.
I asked about the solar panel position as wondered if one ever needed to stand there.
I am intending to place a semi-flexible solar panel on my LM27 wheelhouse roof. I do stand, or kneel, on the wheelhouse roof from time to time, but that type of panel is explicitly stated to be capable of taking that (so long as it's properly mounted). I can't think of anywhere else on the boat that is either less trodden on or not in the way (suggestions invited!).
The LM27 wheelhouse roof has a curve from side to side (I assume other LM models are similar), and the amount of curve varies along that width. Different brands of panels will accommodate different maximum amounts of curvature, which is a point to check. Note also that most say you can only bend them along the length of the panel, not the width.
It can require some investigation to find out the specifications such as maximum curvature etc. for each brand. I ended up dismissing a few brands/suppliers because they couldn't accommodate the amount of curvature I needed, and others because they just didn't provide such vital information. (I wonder how many of the failed panels one sometimes hears about are because such information was either ignored or not provided in the first place.) I am now leaning towards one particular brand/supplier largely because their specifications and mounting instructions are so detailed and clear compared to the competition.

Hello Johnwebb. You are certainly welcome to contact me anytime you like, and the benefit of this forum, is you get so many alternate responses too!
Our black water holding tank is under the floorboards of the V berth. It holds only 15 gallons. Lift up the teak/holly floor boards, and you'll see the top of a fiberglass tank, held in place with many screws. I suspect that the bow thruster would be forward of that, in the compartment under the narrow forward portion of the V berth. My discharge pump, Y valve, and through-hull for the discharge are all in forward space, so perhaps this is what has all been removed/relocated to make room for the bow thruster? I can't imagine how they'd remove the tank, short of simply taking the top off and giving the interior a good clean so it could perhaps be used for another purpose. I have briefly considered, plumbing a supplemental tank under the starboard berth in the V berth... but that will likely be some time in the future. The idea has been fully examined at this time.
Brian, Yes thanks, guides me where to look for the bits. I was indeed puzzled as I had read somewhere that the tank was moulded in so it would be a block to a bow thruster.
I have fitted holding tanks in two boats in the past. When we moved to our, now my, present house the boat is attached to a jetty attached to the house. Boat, house, tools and work bench all together so I went beserk on the Fulmar we had then. Eberspacher, cool box to fridge and big holding tank. Then next boat, before the present Nimbus, I fitted a large holding tank amongst other things such as a 6000+ Autopilot. There was a large space in the locker behind the fuel tank so made up a mockup out of battening and cardboard that both fitted and went through the hatch. Took it to a local company called Tek Tanks and they converted it into a nice heavy weight plastic tanks with all the outlets I had marked up. All went a treat and was about 40 gallons (Imperial not US) which I found to be worth 8 man days. It was actually below the small one that Dehler had fitted. All depends on what I find when I see the boat as we are all in lock down at present. There is even talk of lock down for over 70s being longer which I am not adverse to, with diabetes and age 79 I dont rate my chances very highly. I guess I could drive to a boat and climb on alone to look.

Thanks for the tips on how you went about fitting your bigger holding tank. I'll have to keep that all in mind for when I do take on that project.
Here on Vancouver Island, British Columbia Canada; We are encouraged to stay home, but we are not yet in a lock-down. It seems we've been quite successful at 'flattening the curve' via social distancing, although all pubs, most restaurants and many many stores are closed. I can get to my boat to do work on it, even go for a day sail ... but the folks who live on our beautiful Gulf Islands, don't want any boaters on 'their' islands and the provincial marine parks are all closed for any and all use... Ah well ... It will be over one day!
I do believe that the holding tank is glassed into the boat, but I also believe that it is a separate unit that was dropped, then glassed into place.
The forward end is visible if you stick your head down that hatch in the forward portion of the V berth. It is set back about two inches, beneath the bottom of the partition that separates that compartment from the V berth cabin area. My discharge pump (An electic Henderson Mark IV diaphram pump) is affixed to that same bulkhead. There is a gap between the hull and the bottom of the tank, which I sealed when I replaced my sanitary hoses, such that any accidental discharge of effluent would not flow under the tank, and be nearly impossible to clean-up. The tank vent exits the tank from its forward end (And while the vent hose used to end just above the waterline... right in the bow wave ... I moved its terminal end to a point high up the side of the hull, within the anchor locker.) The tank inlet and discharge hoses, also enter the forward end of the tank.
Stay safe! Cheers, Brian.
The aft end of the tank is abutted to the fiberglass floor beam, that also serves as the foot of the mast support.
As my boat did not come with any means of monitoring that tanks levels, I installed a SCAD Solo Tank Monitor with their optional internal sensor mounted in a hole I drilled into the top of this tank. I now can tell when the tank is getting full! Very important for such a small tank! That model has now been replaced, with this one. www.scadtech.com/tank_monitors
At last got to look at the boat and the holding tank is as you describe. The bow thruster is forward of it. There is a Y valve and an electric pump horizontally mounted. No gauge and the one you gave the link to is the same principle as the one I fitted to my present boat. The tank seems to be black, I have not removed the bit of floor over the top yet to look further. One thing I could do is put another outlet in the tank for a deck pump out. If I were confident my present boat would sell fairly quickly I would make an offer. Difficult. The only main thing she needs is total rerigging as it was last done in 2001. The present owner has done much of what I want in the 24 years they owned her!

Yes, Our tank exterior appears to be off-white fiberglass gel coat, but perhaps one of our tanks was painted.
I have such a Y with a deck pump-out. The hose runs from the Y valve up the prow, through the anchor locker, to the deck fitting. I also relocated the vent for the black water tank from just above the waterline at the bow, to the aft starboard corner of the anchor locker just below the deck, alongside my pump-out hose. No bow thruster on my boat, so I likely have more room, so here are some photos of the forward plumbing on our boat. I replaced the deteriorating plywood that the Y valve was attached to, with one made from StarBoard.
Hope all is well with you and yours, and that the sale of your boat goes well so you can join the LM crowd! Cheers, Brian.
Got round to replying and first thank you for all the information.
I dont need to sell my present boat to buy this one, got enough cash and 3 friends here in the marina where I live have empty berths. I would get away with putting the Nimbus on one for a while at zero cost. Just dont want to be stuck with two boats for long.
I did take a very few photos up in the bow which could be cleaner. One strange thing is it has an inner forestay which you can see in one of the pictures here. The deck fitting is attached to another wire which goes down to an inner strong fitting which drops down just in front of the two small bow lockers. The owner says he detaches it to go sailing so what is the point.
Thought I would add some photos but cant see how to do it, I guess I dont have attachments enabled.

John, to attach photos you need to first click the 'Reply' button on the top right hand side of the 'Quick Reply' box at the foot of a thread. This takes you to a different reply box with a lot more options.
Once on this (more fully featured) Reply box, the way I attach photos is to - click the 'Add Attachment' button at the top right hand side, - then '+ Add Files'. This takes you to a list of files you have on your computer, - from which you select your photo. This will take a few seconds to upload, while a blue stripe changes to green. - You can then choose to 'Insert'.
Note that attachments are limited to 1Mb, so if your photo is larger you'll have to reduce it first.
