What is the diameter (or recommend diameter) of the steering wheel for the Narai Mk IV?<br />
It's not listed anywhere I can find.<br />

<p>Don, do you have pics of building KATIPO you could post or send me? I went thru Building Tiger Blog & saved the construction pics. But would like to see your build and mods if possible.</p>

<p>Don, thanks for the info, the dimensional differences there really help me 'see' the comparative sizes. Now that I better understand the size relationship of the three, I know that the Narai Mk IV is definably the one for me.</p>
<p>I misunderstood the design relationship of the Mk IV to Mk II. I was under the mistaken impression that the Mk IV was a completely different design. I will get Mk IV plans, thanks for the input there also.</p>

<p>It's really great that BB is leading the way building a Mk IV with beams mounted on deck and eliminating the beam troughs. That he has rebuild a Tangaroa Mk IV, built a Tiki 30 and 38 is a really great asset as he understands the structures and designs of both Tiki and Classic Class boats.</p>
<p>Plus he thinks "out of the box" which also is helpful. I would like to use his beam design and structural changes to mount and lash them also if possible.</p>
<p>As far as the modification of beam 3 not going across the hulls like the Tiki 38 (just guessing here) but think it will be doable Since it's similar to the T38. Dan Kunz said that JWD did the drawing for the mod on Forever Young. But will definably ask Hanneke about it. Certainly not a modification to just guess if it's a structurally sound change to make!</p>

BB has made some good points and I like his planned beam arrangement and centre cabin top level.<br />
Incidentally the measurement of the deck level of the Narai I and II was 5 feet and 3/4 inches from the plan compared with the 5 feet 8 and 3/4 inches for the Narai IV<br />
As you may have seen on the Narai IV study plan James calculates an increase total space inside of 150 cubic feet of the Narai IV over the Narai II .<br />

The Narai IV has a slightly wider VEE hull amidships and the 7 feet max hull beam is quite a lot more than the 6 feet 2 Narai II or the 5 feet 8 inch Tangaroa IV.<br />
I made my cabin sides more like the Tikis fixing them to the Gunnel along th shear line with extra ply knees inside . This gives an even greater feeling of space inside.<br />
You mentioned the possibilty of using a shorter beam for beam 3 , the schooner wing sail rig for the Narai IV and II makes no allowance for that and would probably be best discussed with Hanneke.<br />
With regard to plans , if you decide on the raised decks , I would agree with BB , it is not worth the hassle of modifying the older Narai II ones<br />

At 3' 6" in the bunks, that makes that nice & roomy feeling.<br />
<br />
Yes, that's true, the coach roofs would go the same amount higher as the decks went. Or would on stock Mk IV, makes sense.<br />
<br />
I'll be buying the Wingsail drawings cover both the Mk II and Mk IV, so that will get me the rigging info.<br />
<br />
I'm kinda leaning towards the Mk II plans as I'll probably just end up raising the deck some & will lengthen the rudder accordingly.<br />

<p>Head room is gained because as the decks are raised, so are the coach roofs. This allows the profiles of the MKII and the MKIV to look generally the same. (If the decks are raised, but not the coach roofs, then you would have a very low profile coach that might look a little funny. In my case, because I am using lashed Tiki46 type beams on deck, I will keep the profile of the coach roofs lower (to about 6/3" headroom) to achieve a profile that suits the changes I am…</p>

<p></p>
<p>Headroom over the stock bunk locations would be about 3'6", not including the thickness of the cushions.</p>
<p></p>
<p>The MKIV has bulwarks. They are not eliminated from the design.</p>
<p></p>
<p>I have never looked at a set of MKII plans, so I cannot say with any certainty what may or may not be different between the two. I do know that because of the higher profile of the MKIV, that the rudders will be longer, and the rigging plan would be slightly different, among other things I am sure. I understand the $$ thing, because I am a tight ass. I will only be using 3 1/2 pages of the plans for my build as the remainder will not be necessary considering my changes. But for me, to have the MKIV plans it is less figuring to make it right. I will save well over $460 in aggravation.</p>

<p>OK, thanks BB I think I'm finally catching up! lol BTW, what is your name?</p>
<p>The Mk II is listed as having 6' 2" headroom and Mk IV 7' headroom. Then the Mk IV (stock) has about 10" more headroom in the bunks fore and aft of the cabins (if cabin ceilings are the same height above the decks) and better access if crossbeams are mounted on top of deck. Correct?</p>
<p>If that's correct, approx what is the height above the fore & aft bunks on the stock Mk IV, not counting the beam…</p>

<p>If that's correct, approx what is the height above the fore & aft bunks on the stock Mk IV, not counting the beam since it would on top of deck.</p>
<p>Well after going round and round in my head, it seems like what I want is either a Mk IV with beams mounted on decks and add bulwarks or a Mk II and raise the deck. On either I would use Tiki style crossbeams/lashings and widen the beam.</p>
<p>If I do the this, would there be any advantage to buying Mk IV plans over Mk II plans?</p>
<p>I can use Mk II plans and raise the decks to the same height as the Mk IV. I wouldn't really gain anything by buying Mk IV plans as I won't be building Mk IV beams or troughs & don't need the Mk IV plans just to raise the decks.</p>
<p>Not trying to be a tight a$$ but the difference in the plans is $460 that can go towards materials. I don't think the Mk IV plans will have anything that will really apply to my project from what I understand, showing the raised decks. Don't need the drawings for that. I'd rather put the $460 towards the Upgrade Plan Package 2 and Wingsail drawings.</p>
<p>Is there anything I would really gain from the Mk IV plans?</p>

<p>Ok. Gotcha.</p>
<p>The floor will not be raised going from MKII to MKIV. The modifications are at the deck level, which is why the MKIVs have beam troughs (unless you eliminate them as I am doing.)</p>

Just trying to get a mental picture of size comparisons.</p>
<p>Reason I asked about the width of the floor is wondered if the higher sides (I'm guessing the Narai Mk II is taller from bottom of keel to top of deck) and the same amount of headroom meant that the floor was raised a few inches and would be a bit wider since the V of the hull gets wider as going higher above the floor. It was just a curiosity question, not a concern.</p>
<p>I'm asking questions to get a mental picture of relative sizes/dimensions as opposed to looking at a couple drawings with a few basic dimensions. If I saw drawings with basic dimensions of the hulls it would be a couple minutes and would understand the differences. Asking questions makes me sound like I'm being critical or wanting something different than what they are, but not intended that way at all.</p>
<p>Just trying to grasp visually the differences between them with out seeing pics or drawings. :-)</p>
<p>There are three things I would really like. Forever Young was built with all 3.</p>
<p>1) Beams mounted on deck so don't need troughs.</p>
<p>2) Beam 3, not go all the way across hulls, mounted & lashed on inside edge of hulls like Tiki 38.</p>
<p>3) Since beam 3 doesn't go across hulls cabin can be extended aft closer to beam 4.</p>
<p>Don't know if 2 & 3 can be done on the Mk II tho.</p>
<p>I like the look of the beams mounted on top of deck with the lashing upgrade and bulwarks, it saves weight, building time & some cost of plywood, though the bulwarks would use some that would have went to troughs.</p>
<p>I'm certainly not saying that troughs are a bad thing. Just that I like the beams set on top of decks. Which can/has been done on the Tangaroa and is designed that way on the Mk II.</p>
<p>Any other information about Narai Mk II & Tangaroa Mk IV anyone can give I would appreciate it. </p>
