Power windlass for UK 33/35 CK

Postby arrancomrades » Tue Sep 25, 2018 11:16 am

Hello,

Advancing years are making me think of fitting a 12v windlass with 10mm chain gypsy and warping drum. This would replace the trusty old manual windlass that has served me well for 18 seasons and was already pre-owned when my father bought it in 1963 - see photos. Problem is that I can't find anything that fits without either being ugly or needing modification which I've still to tackle the suppliers about.

Fall-back, if I actually go ahead with the project might be to put a vertical windlass on the starboard side of the coach roof, beside the fore hatch which means sacrificing most of the hanging locker but has compensating benefits, like moving the weight aft.

I would appreciate details of any installations that are satisfactory. Home for a few days than away again so limited in ability to discuss. Thanks.

Hello, Mike.

Just back from holiday and seen your post. Castaway has an old S/L manual windlass still, but it is mounted on the after end of the bowsprit, so the chain drops straight into the chain locker right up forward. Of course, this isn't good weight distribution, but it suits us fairly well. I have thought of installing an electric windlass, and several types would fit in that position, though perhaps with different hole spacing. Of course, you would have to move your bitts to make way, but there's going to be a lot to do whatever place you choose. I don't think I would bother to take the chain across to the coachroof; just another line to trip over, and if it's slack at all, it will scrape and rattle with every movement of the boat.

Your heirloom windlass looks big enough to lift the boat, not just the anchor; I doubt if you'll find a 12V one to match it! If you do put a Lofrans or similar on the bowsprit, check the clearance for any manual handle against the mast; I bash my knuckles if I'm not very careful.

Kind regards,

Gerald

Thanks Gerald,

Latest status is that having made a template of the Lofrans Cayman horizontal beast, I've given up on horizontals as they won't fit due to chain leads and general bulk so came back to short-lists for a vertical gypsy and drum windlass with the motor nice and dry under the deck.

Option 1 was to put it to port just aft of the mast with the chain leading just forward of the bulkhead and the motor aft of it. This would be similar to the existing chain locker which will only take 40 metres of 10mm before the pile reaches the ceiling. I would need one of the extended vertical shafts which the manufacturers say are available if you search their websites to destruction - see below. Deck thickness 53mm plus a 72mm chock to get the chain lead high enough for the cathead. (I suppose it could be replaced by a conventional stem-head sheave at unknown mega£££.)

Option 2, which is now the favourite, is to put it to starboard on the coach-roof with a plywood 'tank' in the hanging locker for the chain. This should take at least 50 meters of chain even allowing for a wee sump at the bottom for accumulated water and mud. Obviously, bye-bye hanging locker, but for me on my own this is not an issue. The drum would be much better placed for canal work and for hauling in a muddy chain which could be sluiced down on deck, three metres at a time. I note your comment but the chain would be slack alongside the ropes which already lead from the mast to the cockpit.

The boat was pre-wired at birth and has thick cables which easily reach the mast but would need to be extended for Option 2.

The standard models are 1000W and will pull a ton (or tonne). I don't need nor want this but cannot find a 700W model to suit 10mm DIN 776 chain. Despite Lewmar listing it in their catalogue it does not seem to exist in real life. Both they and Lofrans are impossibly hard to deal with, mostly via my excellent local chandlery and appear to be mostly interested in selling trinkets for wee motor-boats.

So for now and until I finish the other big job which is refreshing the completely seized stuff under the steering pedestal, it's all on hold. As I own 1 x 65lb, 4 x 35lb, 1 x 22lb anchors plus two wee dinghy ones, and a heap of new chain which I bought at auction, I could actually afford to cut free two anchors and their cables for less than the cost of a new windlass, assuming I was unable to haul up with the old manual one due to disability or worse.

(Did you know that the big GRP plate with six bolts under the steering pedestal is CEMENTED onto the deck !?!?)

Merry Christmas.

Mike,

We rely on less chain and smaller anchors, which still leaves us grossly over-specified by Baltic standards!

I didn't know about the base of the steering pedestal. I have occasionally toyed with the idea of reversing its position to gain a couple of inches more room aft of the wheel, but strike that one!

I've just been told that delivery on my new engine is March next year, so if it follows Brexit, I may get done for double lots of excise duty! Fingers crossed for a reasonable parliamentary vote.

Kind regards,

Gerald
