In reading some of the posts about the Nacra 5.7, I'm getting a little anxious about righting this boat after my inevitable first tip over. Is there some mods that I should be doing before my first trip? Is it possible to foam the whole mast?
Initially foam might seem like a good idea, but foam will soak up water in time to treble mast weight, not good. Better to seal mast creating a sealed tube that will float, viola! floatation. Use silicone sealant and seal every rivit, every joint at mast head and mast base, then take mast down to pond and float on water to check for leaks, re-seal if necessary. Now go do some research on righting equipment, there are 2 types, a righting pole that stores under tramp and pivots out when needed and allows sailor to use principal of leverage to right cat and then there's a bag system that uses the extra weight of water to add to the sailors weight to right cat.
Whichever system you choose, you will still have to practise righting technique by taking fully rigged cat down to lake, capsize cat in shallows and then use equipment to right the cat. This will help reduce any/all unknowns which add to the stress/fear factor.
Go to www.murrays.com and check out some of their equipment to see whats available.
Don't sweat it too much! If you have 2 people it likely won't be a problem. Seal your mast and look at the power righting techniques in the Murray's catalogue and Rick White's book.
I was really worried when I got my 5.2, but when I did flip it the first time the boat came up without much effort with only myself. As long as you put the righting line over the top hull near the front beam it should come up pretty easy.
If you are really worried, get an inflatable boat fender and attach it to the top plate of your sail (cheap mast float). It will provide some extra floatation for righting where you need it.
I second the tetherball,$20 fix compared to the $200 Hobie fix. Same idea as my suggestion about the boat bumper, except I wasn't sure if tether balls were just a Canadian thing (kind of a useless game really).
I didn't now those bouncy things still existed! Otherwise I may have suggested them. That water jug only looks a 'little' nicer than the hobie bob though. Not enough to really consider.
Ive got a hobie bob i would sell fairly cheap. PM me if you want it. A well sealed mast will work, the bob just adds flotation to the well sealed mast. Seal your mast then install bob and you should never have any problems! The only thing i would do with that water bottle is fill it with ice, rum, and coke and run a hose down to the tramp with a valve on it!
i like where this is going!!...we are on the verge of a revolution in cat cocktail convenience.. jug of rum on top of mast, mixes with coke 2 liter by boom, valve to big insulated "sippi cup" filled with ice that velcro attaches to trap harness with hose to mouth for hands free caboozeling...freeing tramp space for more cuties!...genious!

Hey, andrewscott, I was going to reply to the Hobie bob posts last night but couldn't get that picture to appear so I made it my avatar with the idea of writing tonight. My daughter and I were practicing righting my 5.0 one afternoon and after about a half dozen times the mast filled up and turtled. I thought the bob was a solution 'till I saw the price!!! Went to the local soft water dealership, picked up an empty 5 gal jug and used some aluminum strap to mount it.(Just used longer pins in the sheave holes) My fellow beach bums thought it was hilarious and started calling me the "Culligan man"! Anyway how did you get that picture on your post? By the way, the jug and aluminum came to about 15 bucks.
1. seal the mast
2. don't cleat the main sheet, hold it in your hand the entire time you sail. This will keep you from tipping over, until you can master righting the boat.
3. sail with an able-bodied crew, when you tip it over, it's easier to right.
4. practice righting when you don't have to do it, so you can do it, when you must do it.
5. Now sail faster until you do tip over, then right it and sail even faster without tipping over.
6. rinse & repeat.
