That dinghy sail around the bar is wonderful! How far up the river can you go in the dinghy? There are two rivers Butley creek and the alde You can get around 15 miles up until you get into the reeds But you need to turn around just before the top of the tide otherwise you will get to spend 10 hours sitting on the mud... been there and done that Lots of birds to watch while you wait. The weird thing is that as an East coaster I thought our tides were just tides. We raced GP14s as kids.... I had four brothers and we had three of them in the family....wish I had thanked my dad properly for keeping three boats in racing condition. Dinghy racing over here is less about boat speed and more about either avoiding the tide by sticking to the shallow bits when going against the tide or exploiting them by sailing down the middle. The courses were set by old blokes in Brightlingsea sailing clubs.... man they tested us... cunning bastards. Never heard of triangular courses until we started campaigning for the nationals.. where we got a good spanking by the guys with boat speed. When working the shore the crew keeps a finger on the centre plate to feel when you touch... thecrew calls the tack and raises the centre plate as you roll the boat off ground. d Ps... writing this at anchor in pyefleet creek on the Colne where we sailed as kids 9 Quote Link to post Share on other sites

dylan winter 1,971 Posted January 12 Share Posted January 12 this morning on the Deben was a real cracker. Jill hates the diesel engine and I am no great fan of it. It is smelly. It is demanding. Every journey starts witrh lifting the floorboards under the wheel house and hanging upside down like a bat. In the past year I have replaced four fuel filters....diesel bug now vanquished. Two oil filters, the impeller x 2. The gearbox is using oil so to fix that the engine has to come out - and I do not want to put it back in. So I have been in touch with the bloke from here https://lightningcraft.co.uk/ this 10kw (14hp) unit will fit on the old engine beds. It needs 48 volts. I have access to a pair of these https://www.torqeedo.com/en/products/batteries/power-24-3500/2106-00.html which will run in series. The chargers are 350 watts. and will fully charge the batteries in 8 to 12 hours. I have room for two 100 watt solar panels When travelling I can often use marinas but I usually keep my boat on a mooring. I am thinking of buying a 2kw suitcase generators for when shore power and solar let me down..... \i sm not sure i could life with a wind generator. For long calm days I have a 6hp long shaft Tohatsu outboard that at half chat shoves the boat through flat water at 3.5 knots. Dylan PS I only have one more leak to fix and I planning on getting a pair of legs for the boat. 3 Quote Link to post Share on other sites

I have the Tohatsu - which does just need a jerry can to get me home. A tank full at half chat will run her at nearly four knots for ten hours. With pilot running and me sitting on the foredeck I can hardly hear it. I agree though, 36 hours bashing into a headwind and oncoming seas will not be possible. Running away, hunkering down and waiting will be the chosen reaction. To spend 36 hours with the engine on is a failure of planning. 3 Quote Link to post Share on other sites

If your use-case means that you plan on spending a fair amount of time in marinas, you have adequate range to get from one to the next regardless of method (ie the o/b in a pinch) then what the hell. Go for it. The PV panels will contribute the SQRT(Fuck_all) to engine power consumption/range so better calculate the hotel loads and make adequate provision for them. I have 2 x 130A AGM batteries and 400W of PV panels for my hotel load. That's plenty for a small 22 litre refrigerator, LED cabin lighting and my array of electronic crap. Separate start battery. Were it me I'd remove the engine & g/box, wash them down thoroughly, flush thoroughly and then wrap in industrial Glad Wrap. Store in shed. Sell with the boat in the future. Who knows, if battery tech keeps improving and costs drop then the range issue becomes less of a factor - PROVIDED you're hopping from one land base to another. Wouldn't work where I live but sounds like it might well where you are. I'd love to graft an electric drive to the front of my Sabb controllable pitch prop & transmission. Just for fun.

Raz'r 5,218 Posted January 13 Share Posted January 13 interesting little math calculator to covert HP to Amps. https://www.inchcalculator.com/horsepower-to-amps-calculator/ A bit trickier to guesstimate how much power needed to get to hull speed - one heuristic is 1hp/ton of boat displacement. on a 5 ton boat, therefore 5 HP, you're using 95 amps. So an 800 AH bank would run you 8 hours. FLA is gonna be quite heavy... Now, on my boat, where I need something like an ability to motor at hull speed for 8 hours (race requirements) and I'm more like 9 tons, I'd need to be using 175amps, or a 1400AH battery bank. $13k worth, and 460 pounds of LIFEPO4 batts.

You can't convert horsepower into Amps, that's a bit like converting apples into oranges... HP is a unit of power and Amperes a unit of electrical intensity. The calculator seem to be geared toward alternative current, but you can trick it by into a continuous current calculator by using a power factor of 1 and a single phase. Or more simply 1 HP = 732 Watt P = U x I so I = P / U For dylan, it's all SI, no need to convert so very simply : I = 10 000 / 48 = 208A then add 10% for inefficiency and call it 250A to be sure! 1 Quote Link to post Share on other sites

That's at full power so it is suitable for dimensioning wiring, not for estimating average consumption, nobody in his right mind would run an electric engine powered by batteries at full power for a long time. If you say that he cruises @5HP that's about 3.5kW (3 or 4 knots may be, not sure), the battery he linked to are at 3.5kW.h so he needs one battery per hour of autonomy... thus it gets expensive pretty quick if he wants/needs some range. With his setup, he's got probably about 2 hours at a slow cruising speed. 1 Quote Link to post Share on other sites

Volts X Amps = Watts Watts ~= HP So with any 2 numbers you can calculate the 3rd which gives you a HP equivalent. HP to Amps is kinda like HP to torque Yes but that's not a conversion as the 2 numbers aren't separated only by inconsistent units. Quote Link to post Share on other sites

Forget your diesel sailing life, Dylan. That's all gone (the stink and 5 kts into oblivion). Your are in a new world of energy conservation. Just do it, be that person. Take the pledge. Honda generators and Toohotso outboards are failure. Agree. I shall try not to use either of them. It should add to the challenge and satisfaction. I am currently mothering about mppt controllers and panels in series D 1 Quote Link to post Share on other sites

olaf hart 780 Posted January 13 Share Posted January 13 Seriously Dylan, you should try to get some sponsorship from a lithium battery maker, you have a high enough profile and your project is a lot closer to the reality of most sailors than the usual YouTube warriors… 2 Quote Link to post Share on other sites

The Q 795 Posted January 14 Share Posted January 14 One thing people forget when converting diesel hp to electrical watts is losses. Your diesel engine feeds a gear box, a lot of power is lost there. It also feeds alternators. Water pumps, and other ancillaries . You get nowhere near the rated power at the prop. An electric drive has none of those losses, though they aren't 100% efficient, you get a lot more of the rated power at the prop. Quote Link to post Share on other sites

That will slow them up a bit I imagine Then they'll realise that the tool they need is in the car, parked at the top of the hill behind The Maybush, and they need to row ashore again. Oh, and the tide's doing the best part of 2 knots. Quote Link to post Share on other sites

FKT In Kevin's defense, he's been sailing that same boat for YEARS with no engine and circumnavigated it that way. He has recently fitted the outboard bracket and a hard dodge because he's getting older and things aren't as easy for him as they used to be. It's different than a sailing newbie who sails sans engine for 6 months and then realizes he can't do it. Quote Link to post Share on other sites

That will slow them up a bit I imagine I take the point, but what stimulated the thought was this comment on another forum: I helped a friend haul out a seized up 3 cyl gen from the bilge of his Gulfstar this fall. We removed most of the bits we could (head, flywheel, etc.) and he had a chainfall to get it up the companionway, and then we just ooched it around the cockpit on 2x6s and other bits of wood and finally onto a furniture dolly on the finger pier. The hardest part was getting it up in the back of the pickup. It was still heavy as crap. Quote Link to post Share on other sites

Too much aggravation going against the tide in confined spaces, too much hassle picking up a mooring ball etc. The Pardeys were quite notorious for their attitude to motors - and cadging tows from those with one of those infernal devices. Anyway, it's all personal choice and everyone is quite entitled to change their minds if personal circumstance changes. FKT Quote Link to post Share on other sites
