« Part 16: Second Dry Fit... Part 17 of Stevenson Projects Weekender Sailboat Build series Part 18: ready...can I shock your system? »

Last week I shared the trials and tribulations of my transom attempt…which turned into a good thing…and I shared all the details there…but I did not post any pictures.

I decided that I should take some pictures before I pull it apart and glue on the new transom…as I said in the last blog I am glad that I did another dry fit since the first dry fit the boat was not as far done…so with the parts closer to finished I have a much better idea of the prep steps and was able to come up with a list before I am stuck with wet epoxy…

Its been a busy week with soccer practices and games…but i may put the transom on tomorrow…so—-did not want to do it with out pictures on this dry fit—-even though some of these pictures look like the first dry fit blog…

So this blog is really just the pictures for the details on the previous blog…for more details click back to blog #16…

Below: The First picture shows the NEW transom…I am really happy with the over size and will just trim off the edges later…

Below: The 2nd picture shows the “inside” edge of the transom…the fit is really nice where it touches on the boat bottom.

Below: The 3rd picture shows the deck clamped on to the new transom and stringer…it looks like the deck slopes down to the right…but it actually slopes slightly up…and the “right” edge—-or edge closest to the view is over sized…like the bottom…once all glued up I will trim each side off before putting the sides on…

Below: The 4th picture shows one new slight concern…remember the boat bottom has a notch that allowed it to slide up higher on the keel?...I realized that would affect the deck…it now also needs to move up slightly…at least right now the tip comes past where the existing space is for it. My worry was that the boat bottom and deck need to match—-but I am okay as long as the widest part of the deck is over the widest part of the boat bottom—-right?

Below: The fifth picture does not really show it…but the other issue is where to put the forward bulkhead…the plans call for the small stringers (or supports) that the forward bulkhead attaches to on the bottom is 24” behind the keel/keel stem joint…but since the boat bottom is up 1.5 ” that means the forward bulkhead should be too…this was at least my thoughts the whole time—-but with a more accurate dry fit I was able to confirm that the sides of the forward bulhhead come out much more correctly to meet where the boat sides will touch…so I am feeling good that the correct position should be 22.5”...

I COULD do two one of two other options to keel the forward bulkhead at 24 inches…I could add addtional girth or width to the sides of the bulkheads so that the boat sides still have this support….OR I could re-do this bulkhead and just make it wider…The reason why these two options may be necessary is that the position of the forward bulkhead determines where the mast/mast box will go—-will 1.5” forward be that critical—-remember—-it will still match the plans in relation to the boat bottom and boat deck at 22.5”...
Let me know what you think…

Below: Picture 6th picture just shows the new transom…and if you look closely you can see the notch which allows it to reach below the boat bottom…giving it grreater coverage…

well…this was supposed to be a short entry…lol…my students always say I talk too much…

A fascinating blog! Thank you for posting pictures! It looks like you are really making progress now Matt. I hope it won’t be too long before it gets wet.

Matt, think of what you did to move the bottom forward. You notched it deeper and moved it 1 1/2” deeper onto the stem.
Do the same with the deck and everything will fall into place as it should. I think that your initial mistake is likely that you made the stem too deep from forward to aft face. It doesn’t matter, just do to the deck what you did to the bottom and it will realign.

Thanks paul! With the more accurate 2nd dry fit…that is what I realized…everything seems to line up with that adjustment…

Thanks Mark…hopefully by next summer….if I can just get the boat to look this way—-glued up…then it will be lots of smaller jobs for a while…things I may be able to do during the week as well as weekends…so hopefully it will move along…but I need to get these same big assemblies put together…

Hi Matt;

This sure looks like a fun and challenging project.

Nice work. Good thing you’re getting professional input from Paul. I’m sure that’s very reassuring.

So the issue with the mast position is where it puts the center of area of the sails relative to the center of lateral drag. Too far forward and the boat ends up wanting to turn downwind, too far back and you end up fighting turning up-wind. I believe that if you have your druthers you want it so it wants to turn up-wind if you let go of the tiller (rather than turning downwind, which would lead to a less stable situation).

I’m not visualizing this as well as Paul, so I don’t have a picture in my head as to what the position of the mast is doing relative to the fore and aft area of the keel. However, I don’t think an 1½” is going to be too much, and you’ll probably have some fore and aft adjustment of your mast angle with your stays.

But I also haven’t sailed in many many years, and then it was always smaller boats, and swinging centerboards change the lateral drag position as you adjust them so the fact that the rudder is providing a substantial portion of that lateral resistance is just fine.

Very cool! There are probably a lot of places I’d mess with the plans, but the fore and aft placement of the mast ain’t one of them. Good call on the 2nd transom. Let me know if you need help and I’ll try to make it happen. I’ve cut down on the weekend teaching thing and Kim always love to go wine tasting.

Thanks guys…

Dan…good thoughts…the difference would be 22.5 inches aft or 24 aft of the keel/keel stem junction…if I keep it at 24” I will just need to re-do the forward bulk head or add some side supports…to extend the edges…

Chris…anytime buddy…we keep missing each other…right now its my daughters soccer season…so saturdays building time changes from week to week…it would be fun to finally meet you…

Matt, I’m so lost in all of it that I’ve got nothin’. It’s a great project & instead of adding anything of no value to its completion, I’ll simply be content to watch from the wings & quietly cheer you on to completion. I’m looking forward to seeing it progress. -SST

TRANSOM MOUNTED…officially mounted the transom today…and my marriage is still in tact…barely…BUT…it is on…and for more fun I decided to spread clear epoxy over the entire boat bottom…I have had several people tell me its easier to do it now then when the boat is all closed up…

tomorrow I hope to flip the deck…flip it and coat the underside with epoxy…

ok…i did it…I flipped the deck and spread clear epoxy on the bottom side of the deck…I went a little thicker and I think one coat will be good…just in time too…since the rain is here…and I needed to get it under my tent…

big steps coming…running out of “little” things to do…so I will have nothing left but the big assembly…lol…
