The Engine / Re: Electric outboards.
« on: June 05, 2022, 06:35:48 AM »
Our motor is the 1kw Evo Plus. It?s very torquey and will push us along at 4.5 knots for 75 mins but at 1/3 power we?ve had more than 9nm from one battery across Falmouth Bay. With planning and care the range from two batteries is sufficient. Our petrol outboards were quite idiosyncratic to say the least. We know the electric motor will start first time every time.

The Hull / Re: Lee board refurbishment
« on: March 28, 2022, 04:36:03 PM »
The plywood base for the V berth was unscrewed which gave just about enough room to get a multitool / angle grinder type thing in to remove the shoulders of the pin supports. Then the pins were just tapped out.

The Engine / Re: outboard dimensions
« on: March 15, 2022, 02:27:41 PM »
We've had a 6hp tohatsu in the outboard well and it fitted with around 5mm to spare.
I think ours was the standard shaft but, the height of your transom is the key thing. We lowered ours and from what I've seen, not all of them are set at the same height anymore.
The Tohatsu was perfect in many ways but we swapped it for an Epropulsion which is also a great solution.
We've got some video of it on Youtube.

The Hull / Lee board refurbishment
« on: January 28, 2022, 10:37:43 AM »
Amongst some other tidying up and improvements scheduled for this winter, we?re having our lee boards serviced by Jackson Composites in Leicestershire.

These are some pictures and a description of the process.

Pete extracted the pins without cutting into the moulding by going in through the V berth and then grinding away the shoulders of the lee board casing which held the pin itself

The pins were very corroded at the point where they were glassed into the hull, but not where the met the lee board itself. Maybe this was a reaction to three decades of a resin / saltwater mix.
New stainless steel pins will be fitted and should give another thirty years of service.

The hole in the lee board though was huge in relation to the pin and it will need a lot of rebuilding and reinforcing before the board is refitted. It was not however an elongated hole which you might have expected after the decades of wear and use.

Thanks Dave.

That?s really kind of you.

Where do you get this information from?

WB facts seem hard to come by.

Best wishes

Gerard.

Glad you enjoyed them. We do it for fun, have you seen the latest one from Cornwall?

Just wondered you had any info' regarding WB18, Sea Jade. We were told she was built in either 1983 or 1993, what do you think?

Here's hoping.

Yes, we saw both WB's on their moorings. Very impressed with the standard of finish.

Glad you enjoy our videos and yes, I'll do some digging around the dates.

We've got number 18, Sea Jade. We'd like to know when she was built. We were told that she dates from 1993 but, given this info' it seems unlikely. Is there a register / timeline anywhere?

We love the Epropulsion motor, it?s a Spirit Plus Evo so  charges itself if you?re doing anything over 4.3 knots.

There?s loads of torque from this unit so it?ll punch along through some big seas and tide really well. It?s ideal for a displacement hull I?d say.

We haven?t measured things scientifically but, this summer we motored all the way from the Helford passage to Mylor at about 2.5 knots (around 9nm) and we still had about 20% left in the battery when we arrived.

At full power I think we can hit 4.5 knots but this will only give 75 mins runtime. Half power gives about 3 knots speed and perhaps three hours runtime.

We?re going to get a second battery next year but for a backup this year we had a Lifos 12v battery and solar panel. We never ran out of power but you do need to think about how you use it.

As for fitting, the motor sits in the outboard well perfectly but the battery is too big so you?ll need to put this in the rear locker and use a dedicated extension cable.
The short shaft is the right length for the boat but does protrude beneath the skeg by about 80mm so is a little vulnerable in the shallows.

To sum up, the ease of use is fantastic. I?d recommend it and say that the power is adequate. The range though might be an issue with just one battery in a strong tide / if there?s an emergency etc.

Repair Yards / Recommendations wanted.
« on: August 14, 2021, 07:39:35 PM »
We?re thinking of refurbishing our lee boards / bilge boards and having some other minor works done to WB 18. Does anyone have any favourite boatyards or indeed any to steer away from?
