<p>Although this thread has come to a halt, I would like to add a comment. SAMSA (South African Marine Safety Authority), the people who like to re-invent the boat, have made it compulsory to have a management system that allows to evacuate every section of a ship individually. That means you either have to install x number of pumps, or make a complicated piping system with pumps, pipes, valves, through bulkheads never mind. So I have 4 water proof section in each hull. So I had to make holes…</p>

So I had to make holes in each of the bulkheads, install pipes and valves (to re-establish the waterproof integrity of each section), and then add electrical as well as manual pumps. This on a wooden catamaran that can not sink. Shame.</p>
<p>I am not a racist, but why do people who are new to government have to change things that they do not understand? No, we are not talking about a bulk carrier. Just a sailing boat over 30 foot. Wind and waves do not bother me. But those!</p> Bonjour Frank,

Bonjour Frank,<br />
I will install a fixed pump, may be as LUkas, whith a hose, long enough to reach any compartement of the boat. Thank you for the photos.<br />

Hello Georges,<br />
if you like to install a pump in each hull - very fine! but install a hose only for the biggest compartment (with my NARAI MK IV this is the middle section). I would also say like othe comments - dont cut the bulkheads! those are complete watertight compartments. in short I may send you some pics on my page where you can see my pumps (mechanical and electrical) installed.

Thank you Robert. In a few words, no holes in tha bulkhead.<br />
Bertrand i can't reply directly.<br />
What kind of foam do you use. I guest, it's a plyurethane one, called with closed cells. Where do you buy it? Is thère some polystyren treated against water, that i can use?

Definitely do not put holes inthe bulkhead: my hinemoa got holed in the forward compartment whilst on the mooring. I do not know how long she had the hole in her but the only reason I found it was that she was floating an inch or so lower on one side when we came alongside the jetty (it was at night). The hole was about 2-3 inches in diameter and rapid baling with a builders bucket made no impact until we had dried out and sealed it.<br />

Bonjour Georges<br></br>
<br></br>
As initially I planed to get French flags for my Tiki46 and 30 I filled the stern and stem areas with foam I molded in plastic bags for my Tik30 (see my Tiki30 building blog : <a href="http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki-30-n119" target="_blank">http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki...</a> )<br></br>

Bonjour Georges<br/>
<br/>
As initially I planed to get French flags for my Tiki46 and 30 I filled the stern and stem areas with foam I molded in plastic bags for my Tik30 (see my Tiki30 building blog : <a href="http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki-30-n119" target="_blank">http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki...</a> )<br/>
and for my Tiki46 I bought thick foam panels of 10cm thickness I cut and adjusted before to close the upper hull part (see my Tiki46 building blog : <a href="http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki-46-n2-pha" target="_blank">http://wharrambuilders.ning.com/profiles/blogs/building-of-the-tiki...</a>).<br/>
(In the next weeks I'll take the time to actualize it but now my priority is to paint all the outside parts before the coming back of the cold days).<br/>
<br/>
As the foam is not glue to the hull, if necessary it's always possible to put off all the foam pieces ( each one has a number recorded on a plan). It's better than with plastic bottles because all the space is occupied by the foam (don't fill your buoyancy areas in filling them with bottle + pouring foam because it will be very difficult to remove them if necessary).<br/>
Another great advantage is if one hull hit at high speed some heavy floating object, the big part of the energy will be absorb by the foam and the damages will be less than if the buoyancy area is empty or filled with plastic bottles.<br/>
<br/>
On my Tiki30 I had only a portable hand pump I never used. In the floor are little round waterproof inspection hatches and I used a sponge to put off the few water entering in the boat by the main hatches. On my Tiki46, due to the diesel engines with their shaft, I'll put in each hull an electric bilge pump + a manual pomp. I think if there is a lot of water, a bucket is very efficient.<br/>
<br/>
Bonne construction<br/>

I think that water bottles is a very good idea. I will fix them all together with a special foam use for house bilding, that resists to water.

Let me add that Bob Beggs, while getting ready for the single-handed across the Atlantic race, OSTAR, accidentally holed one of the forward compartments while launching off a beach. He did not discover it until after a shakedown cruise, when he found the water in the compartment! So, they can handle a bit of water . . .

Georges,<br />
<br />
At the foremost bulkhead, accessed through the forward hatch, there is an inspection port. There is a similar pot in the aftmost bulkhead, accessed through the cabin. What I have done is place empty capped plastic water bottles inside these areas for extra flotation.

i didn't build my boat, and have done nothing to improve bouyancy. i think it is well designed and does not need any improvement to bouyancy. it has already 6 seperate watertight compartments, so if one gets a hole the other 5 should easily keep it afloat. also, it is made from foam, so even if it breaks into 100 pieces it should still stay afloat (but might be lacking performance to windward :-) )
