Daggerboards - Dang Heavy!!!

What are daggerboards exactly? According to wikipedia: "A daggerboard is a removable vertical keel that is inserted through a "trunk" in the center of a vessel's hull, usually amidships. Daggerboards are usually found in small sailing craft such as day sailers, which are easily handled by a single person. Daggerboards are not usually ballasted but are locked in place by a clip or pin. Unlike a centreboard, which can be set at different angles to the hull of the boat, daggerboards are generally limited to a single perpendicular position relative to the hull. If a daggerboard is located off center, it is called a leeboard or a bilgeboard".

Got it? I know, right?

What I've been told is that the daggerboards we have - one on each side of the boat - are used to give us more speed and efficiency in certain wind conditions while we are sailing. Again, wikipedia says: "The purpose of the daggerboard (or any keel) is to balance the force of the wind on the sails. Without a daggerboard or keel, a sailboat could not sail up-wind and would simply be blown sideways".

I'll confess that it is a bit of a mystery to me exactly how all the wind and water forces combined with sails, keels, and daggerboards work together to make a boat go. Before we started all this I just thought that boats sail whichever way the wind blows, kind of like a hot air balloon. But it turns out, that depending on how sails are rigged (location, direction they are mounted, and what type of sail) and trimmed (tighted or loosened), sail boats can go almost any direction they need to except directly upwind (into the wind).

The direction the boat goes in relation to the wind is called the point,reach, or haul. This might help you understand



So our daggerboards, when lowered, allow us to shrink that no-sail zone into a smaller cone heading towards the wind.

When we put the boat out on the hard, we took out the daggerboards so we could inspect them and the pockets they fit in, make any repairs needed, and repaint them. A couple of posts ago when I said we almost had all the paint done, this was the last little bit we had to do, paint more barrier coat inside the daggerboard pockets. We got that done over the weekend and checked it this morning to be sure it had cured. It has.

So, now to getting them reinstsalled. That means lifting dang heavy boards and carefully putting them into the pockets they fit in - without dinging them or the boat up. While I type this, John is working on making sure the blocks (pulleys) we will use for this, and that control our ongoing management of the boards, are working well. Then he will hook up the boards and I'll come out to work the winch for him. Our friend Thor came over the other day to help lift the boards up into a staging position.


Hopefully we will find a time today when the wind dies down so we can do this! Stay tuned!

Getting this party started!

Well, here we are. A couple of years ago we decided to buy a bluewater sailboat and sail wherever we want. We had a plan. A five year plan. We still do, it's just changed a bit. Originally we were going to spend five years learning about sailboats and trying them out during various vacations to decide 'the perfect' boat for us. Surprise, surprise! We found an older boat almost right away. It's a long story that most of you have heard us tell. Maybe one day we will post about it. Fast forward to now - August 2021. We've had the boat out on 'the hard' in the boatyard, working on removing 25 years of old bottom paint plus converting her over to 100% electric! We are totally committed to 'splashing' (getting this boat in the water) by October this year so we don't have to pay for another year on the hard. Plus, since the boatyard we are in is likely going to be sold soon, we aren't even sure we would be allowed to stay another y

Hurricane Ida Remnants = High High Tide!

We are so very very grateful we got those four coats of paint on last week! We basically had three nearly perfect days for painting. Hot and humid, but nearly perfect for our job. This week, Hurricane Ida remnants would have made that job much harder for us. That's not to say we are suffering any hardship from Ida, and our love and prayers are with those working hard to recover from her wrath, especially those who have experienced loss. We are forever grateful for and amazed by the many who sacrifice and work tirelessly to clean up and help others recover. Thank you all who serve like this. ❤️ We have been at this marina and boatyard, Georgetown Yacht Basin, for just over a year. We've seen some high tides while here, but nothing that covered the docks. And when we were at the US Sailboat Show in 2019 in Annapolis, due to a supermoon tide and strong and steady offshore winds, Annapolis and the surrounding area experienced a super tide that left us wading thr

We Splashed!!!

Wow, Wow, Wow! Friday was quite a day for us! Yes, you are seeing that right. WE ARE IN THE WATER!! Before you ask, however, no - that doesn't mean everything is done and we can now just travel anywhere we want. Not by a long shot! We have the electric motor and saildrive mounted - with no leaks! but there is still a lot to do to get them all wired up, controllers, monitors, and charging inverters connected, throttles mounted and connected, etc. That's definitely the priority now. But, first let me share the amazing holy-smokes wait-what experience that was Friday! In my last post I talked about the sudden decision to go into the water the next day and our late late night scramble to get everything ready for that. They told us they would be ready about 9 am to come move us down to the water. So, after a very few hours of not the most restful sleep, we got up at 6 to keep getting things ready. I still had to move all the stuff I lifted up to the back deck and g
