Hello all,

I know it has been a while...but I am still alive and still trying to finish the #@#^!?# boat! I am trying to figure out and mark the waterline on the hulls but there are no information or measurments in the plans. I have seen the idea with the transparent hose pipe in various blogs but from what I can understand you need some numbers provided by the designer to start with. I thought that someone of would have an idea on how to do it or, even better, could provide me with some measuments from a finished Tiki 31. Thanks in advance,

Manos

I will try and post later today or tomorrow.  If I were you I would bring your line up about 6" taller than the actual water line.  I will be raising mine next month.

I am looking forward to reading your comments, thanks Thom.

Manos : ref waterline marking I have sketched mine out on one of the hulls with a laser level having firstly done proportional measurements from photos of other Tiki 31s, but mostly of Phil le Maitre's boat which I knew reasonably well, which was built to plans with similar material and loading. Water levels (ie the builder's tube  level from the old days)  are are alright but a lot more work to do this with.

Don't worry about how long it has taken to build your boat,  you haven't a chance of beating my record (also of roadmiles covered and seapassages before launch)!

I don't know if you have estimated the weight of your hulls but I guess they will be above the estimated weight of the hulls as stated on the plans when I bought them (think circa 1989). I think that was underestimated, but maybe Wharrams have updated the weight since then. But I guess fir-ply would be  lighter than my hulls for example.

I think I would use that if I had another life to build another boat in my formerly non-existent spare time....rough, light, with a sell by date.

Laser levels are useful! With proportional measurements from photos of boats built from similar material.

Hello Ian,

Thanks for the reply. I am also now focusing on gathering information from photos of other TIKI 31s. I have turned the second hull upside down and I have almost finished glassing it. I then intend to turn it straight again, make sure it is level and draw the waterline in approximation, taking into account the larger weight of the hulls as you also have noticed. I believe mine must be around 500 kg each (added material for enclosing the central cockpits haven't added more than 50-60 kg to the weight of each hull)......As for the record of road miles...I am not sure who is holding it, but I hope we both brake it on sea miles eventually!

By the way, your boat is beautiful!

Hello Manos, ref weights I am just going from the feel of it, as I am used to shifting big oak beams and small/medium wooden structures which has been my worklife scenario for a long time. I have a precise pivot point I know well on the hulls, it's actually not exactly where you think it would be, a bit further back, which seems exactly right from a sailing point of view. I have left the yard trailer I made in Guernsey and it now has a second life for a ladies  rowing skiff on the sea there.

Shifting the hulls has always been a question of this. I have had  5 different worksites up to "the marina" now which is the sixth! and final I hope.  It's just the platform to do now, and that's going to be minimal and light.

I made circular "wheels" for turning the hulls with shutterply and 150mm thick pine sandwiched between. I turned the hulls  singlehanded with two of those and a winch. I had to dig a hole in the ground to swing 'em.

Nothing's going to stop me now!  And you too I think. Bon courage!

Hi!

As for the mistery of mastrake, i can tell you that besides causing weatherhelm a certain amount of mastrake wil also make you tack easier. traditionally the aft mast has slightly more rake than the fore mast. This is also a matter of personal preference. So it's something to experiment with.

Hello,

My wife and I had been looking at sailboat options for adventuring with, with the possibility of using it as a live aboard for extended durations, and possibly permanently.

We’d looked at rebuilding an older boat, but we felt it would actually be better and easier for us to build our own. That will give us an intimate knowledge of every nook and cranny, as we’re pretty self-reliant and will do all maintenance and repairs ourselves.

We appreciate the relative simplicity of the Wharram designs, and that maintenance and repairs can be done with a minimum of tools. We looked at several other designers, but we felt that the Wharram designs were the ones for us.

We’d purchased the study plans for the Pahi 26 and 31, as well as the Tiki 26, 30, 31 and 38. They all have pros and cons to them, but we decided to go with the Tiki 31 after a couple of quick back and forth with Hanneke on some changes we’d like to make, and hearing that the changes are mostly alright to make, and the one major change is feasible.

So we’re now the proud owners of Tiki 31 plans #128!

We chose the Tiki 31 because we felt the Tiki 38 was too big for us (to build and to use), and we’re planning some changes to the cabins to make it more like a smaller Tiki 38 with Pahi style cabins and the beams in troughs at the top of the cabin. That’s our big change.

The other ones are more common; increase the length of the masts for more deck clearance, move the ramp to behind rear beam and have the cockpit beneath the mizzen sail, with a deck pod in front of it with a full double bed.

I’ve just started putting the bulkheads and hull sides into CAD to plan out the changes and see what it would look like and make sure it accomplishes what we want. After I’m done with that step, I’ll post some pictures so you can see how it’ll look yourselves. Just don’t expect them anytime soon, it’ll take a while to get it to the point that we’re satisfied with it.

I look forward to talking with you all and sharing our progress as we go.

No better time to do the computer work than a Canadian prairie winter.

Del
