Paving paint is what they paint on outdoor concrete surfaces. Got it from the local hardware shop (Bunnings). Thinned about 10% with water and sprayed with a conventional set up. Beginning was dry by the time he got to the end. Sprayer is good, but not a pro. No runs, no sanding scratches showing through after one coat. Can also brush or roll it, but, possibly because of my cheap brushes and rollers, it looks pretty rough. Will be brushing the mast tomorrow.
Rob,
Can you expand on the "Paving Paint" description.
Is that the water base version of what they paint stripes on parking lots?
Is it sprayed or rolled, on"? Airless?

The less height and beam in the lee hull the better, within stuctural and accessibility limits. �Sol2 is 400 wide, this is too much for a fat fellow like me to put bulkheads etc in and is too narrow for the beams. �The next one is 600 wide across the deck. �My deck thinking was the boat would be through the wave before the water needed to flow from the decks, so the extra windage of raising and rounding them was not worth the effort compared to the ease of building. �The next one has a bit more shape in the hulls which enables more triangular sections at the bows, and possibly a reverse bow (see how the bending works out).
No updates, Sol2 is in the yard while I wait for the 15m table (still!). �El is painted (50 bucks worth of paving paint sprayed over 40 grit orbital finish and it looks fine. �Low gloss (as required), raw carbon spots are mostly covered (should have sprayed a second coat on them) and it thins and cleans up with water. �Should be tough and UV resistant. �Waiting for the sail (slides replacing pocket luff and an extra 2m high) so I can beef up the mast at the slide locations, hope to be sailing this week.

Hi,
I am uncomfortable with the very low height of Rob's solitarry, especially for the mast bury.
I was just looking at a C class video - their bows turn up at the ends to give much greater volume, while the rest of the hull stays quite low. I think this would be good on a lee hull of a harryproa.
Because there is so much material in the meiddle of the lee hull it would be nice to keep it down to a minimum.
Could you use some kind of extra bulkhead and maybe support struts to take the mast tube up higher out from the top of the hull? Also perhaps doing the same at the cross eam.
Those modern trimaran cross beams curve down sharply to the floats. I don't know what would be strongest. I would have tought that it would be OK to just make a small sectio of the hull come up to the extra height� using extra material.
If you look at some of the pictures or calculate the surface areaas for buying the foam it is quite a lot goes into your lee hull on the old harry and visionarrys.
Solitarry is so much lower and smaller in surface area.
The ww hull must have height - to stand up in, though it could be kept pretty low down with a camping rapscallion style.
