Solitarry is a) very light for it's length and b) an experiment. I am hoping to lower the bows by up to 50% once I see how it works. The mast bury is irrelevant as it is supported by the beam at the top bearing, not the hull. If I toss the beam (pretty likely, but I want to try it first), there will need to be some extra structure added. The first harry had the structure in the middle and it worked well for the mast. The beams were on posts which did not work so well. Curved beams like the tris are a great idea, but a lot of work to build.
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.
