Thursday (Day6), Team RAF relaxed at the finish line on a lovely beach which looks out over Florida Bay. Kotzebue and SOS took me (DWSB) out for a ride in a catamaran configuration of the "Fall" and "Rise" boats. Our maximum speed was a hair under 12 knots. Winds were NW at 17-18 knots.

SOS downloaded wonderful photos and movies from his camera. Want to see a few of the photos?

One happy sailor.

Hey Guys,

Can you tell me more about your experience with Rise & Fall in cat mode? Do you think that it would make a good little cruiser in it's own right? the boat just loks like it has so much more capacity than my Ulua in terms of freeboard. Is that as designed? I know the deck is added, and the transom was trimmed some. Any impressions about your sail? I'm thinking that would make for a sweet boat to camp on at anchor with a little deck. Obviously quite capable in tri mode as well.;-)

When you get a chance, please write up an article for publication-I'll bet you get some bites.

How long was the luff length of your sail in it's race version? I'm making the conversion from a too heavy homebuilt mast to a setup like yours.

That's one heck of a camera phone!

The boat in cat mode was pretty interesting. We never completed the boat-to-boat connection for the rudders, so it was a little strange using mostly one rudder to steer the two boats.

The biplane rig (two sails up at the same time) was really strange. In the trimaran configuration, we couldn't effectively point higher than about 40-45 degrees off the wind. But in the cat configuration, the boat was able to sail at approximately 20 degrees off the wind, but the windward sail almost entirely blocked the leeward sail at higher angles (between about 30 degrees and 120 or so). Dead downwind was nice (wing on wing with one sail to either side) but sailing across the wind again caused some blockage of the downwind sail. I'm pretty sure this is not the optimal rig, more testing might give more info.

The sails worked very well, they each were a little different resulting in the two boats performing slightly better in different circumstances (upwind/downwind). Both had a luff length of 15 feet. Roller reefing is definitely a good way to go for cruising, because it allows infinitely variable sail size selection so you don't need to hike out to avoid burying the amas.

As far as masts go, we saw a lot of great homemade masts at the watertribe event. Wizard's "Sand Flea" used an extremely light strip-built hollow mast, and the top mast sections on Roo's EC 22 were also of hollow wood construction, with a carbon fiber outer sleeve. Both of these types of masts could be suitable alternatives to windsurfer masts if properly sized. Note that the most expensive parts in our rigs (and probably the whole boat) were the five-foot 2.5" aluminum mast extension tubes, running about $75 apiece plus shipping from Dwyer masts. If you want to avoid this expense you may want to investigate other mast mounting methods.

P.S. Alan's camera is a Pentax Optio W20 waterproof 8-megapixel camera. We took a 4-gig card on the trip, and got lots of photos and videos. We'll upload them ASAP!

Thanks for the additional details!

I too have the Optio--I thought those were camera phone images, and my jaw just about hit the floor.

Did you add any to the height of the Wa'apa hulls? What changes if any would you suggest for the boat if you had it to do over with the benifit of the experience you now have?
