Daggerboard hit on nacra inter 18

No, the Nacra Inter 18 daggerboard will not come up on it's own. If you hit something at speed, you will either damage the board or hull or both.

If your hitting big rocks with either boat, the boards and rudders won't last long.

I hit a log floating under the water this season w/ my I17R (same daggers as I18). I got a small crack in the leading edge, and a chip out of the trailing edge, where it collided with the dagger trunk. The dagger trunk wasn't unscathed either -- it leaks -- but I don't have pics.

My point being: No, they don't kick up. That should be obvious from a look at the design, though.

I've hit bottom and jammed them several times.

I own a mystere.

Cenerboards are not immune to the same damage as daggerboards

USUALLY they will kick (rotate) and avoid being damaged but damage to both leading and trailing edges can and will happen sometimes

The nacra boards are pretty stout and will take pretty good abuse. I hit my share of things on the i20 at speed, including a sea turtle. They will not kick up by any means.

The mystere you mentioned has a 10ft beam. If you don't need to trailer much it might be a great about for you. If you need to trailer, this should be a serious consideration.

Thank you all for your reply. They are pretty much what I was expecting. Like yurdle said it's pretty obvious by the design but since the owner was telling me that it would slip up I preferred to check with you guys.

Bacho: Trailering the Mystere and its size has been the reason why I bought the Nacra Inter 18. The other one is the Nacra is in better shape.

Again, Thanks.

Keep one hull out of the water and you half your risk (wink) If you are sailing in shallow water then like any boat you need to take precautions. That was easy

all the 6.0xl's around here came with 2 sets of beams and 2 tramps so you can make the boat either size (10' or 8'6")

The mystere you mentioned has a 10ft beam.

I only put my dagger boards down about half way (Inter 17) I have run aground (sand) at a pretty good speed, flying a hull, dagger board held enough for me to pitchpole. I would NEVER want to do it again and it was a beginner mistake that could have been costly. I guess what i am saying is they are stronger than you think.

AB, did you pick up one of the Inter 18's for sale near Montreal? They both looked pretty good, priced very attractively with spins & carbon poles/snuffers.
I decided not to go with an Inter due to the shallows coming into my dock, I just know I'd screw up at some point while solo, probably big time. The bottom is soft, so maybe it's not as bad as I imagine.
Since I solo most of the time, I'm leaning towards a Mystere, or Tornado. I like the rigging that allows both center boards to be raised or lowered with one line.

Edchris,

I took the one at Aylmer lake. It is in pretty good shape and was 1900.00 less than the one in Ascot Corner. I didn't see this one though.

2 lines
1 for up
1 for down

most of us remove one or both of the lines... too much spaghetti onboard (i removed the line to lower the board... i do it by hand, figuring i want to be able to retract them asap if i hit a whale, or submarine, or other)

I've run aground with the daggers all the way down and the spin up. It's not fun, certainly not recommended, but not the end of the world. Far better than running head first into a dam or breakwater.

Thanks, that's what I was thinking...the writing didn't come out that way. I saw that setup on 2 Mysteres here,(5.5's)
For my particular situation it seems a great convenience item. I never thought of not really needing the "down" line

First tack on my "new" used I20 and hit a sand bar 100f off shore, snapped the dagger boarder clean in half. Ended up spending 850 getting a new one shipped. Now I am extra cautious about knowing where I sail and whats under the water.

So while sailing in Richmond YC Multihull regatta we hit a seal in San Francisco Bay going about 20kts - both of us on the wire, the boat came to almost a complete stop in the water. After we got everything back onboard we pulled up the board and the front edge was clean, but we took a 2in chip out of the trailing edge.

Left the boat in the water that night to race the next day, came back in the AM and entire starboard hull was filled with water. :-O Turns out we put a 1in crack in the daggerboard trunk. The repair cost $1500 and we had to cut a hole on the inboard of the starboard hull and repair the trunk from the inside. Thanks to Craig at Elkhorn Composites the repair on the boat and board came out fantastic.

Moral of the story, break the board when at all possible, not the hull!

One thing to note if you are doing a repair on a MKII. There are bulkheads on the front and back of the dagger trunk, and there is another bulkhead that is midhull vertically and surronds the dagger trunk horizontally but is not attached to it. This is important to know if you are doing a repair as your access hole has to be BELOW this horiztonal bulkhead or you can't access the bottom of the trunk where it meets hull.
