Yes, you have to disassemble the boat completely to be road legal. It takes just a few minutes to remove the trampolines and can be done by one person, however it is easier with two people. Removing amas requires 2 or 3 people. Removing akas (wings) requires 2 people. It will take about 3-4 hours to...

Can anyone confirm the ACTUAL diameter of main sail sheet and genoa sheet? The spec in the manual says 10 mm 18 m for both. I verified the length. However, the diameter appears to be 11 mm. Also, how do you decide to replace the sheets? I replaced my genoa sheets when it was chafed where it goes fro...

Imagepipe_2.jpg Imagepipe_0.jpg I wrote years ago about Dyneema failure in my main halyard. Then a few years later I wrote about another Dyneema failure in my board downhaul. I wasn't sure what the cause was and speculated that it may have been related to some chafe and/or compression loads. Now I ...

It's difficult to find insurance on ANY trimaran in the US. Contact NBOA. They seem to still be able to find insurance companies for trimarans. Although, every few years an insurance company drops out. I've had 3 or 4 different insurance companies through them over the last 20 years. Also, make sure...

To reach the relief valve you have to be on the swim platform bending and reaching down low or (preferably) on the swim ladder steps.

I find that the outboard is useless as soon as the waves build up because the prop comes out of the water. On the other hand, if there are no waves, my Honda 10 managed just fine to keep the bow into the wind. We weathered a couple of storms in harbors with winds 30-35, even had to re-anchor into de...

I am not sure if my answer will be helpful to you, but I had to replace my ST40 wind instrument. The mast-top unit came with a very long cable that could not be disconnected from the unit! So I installed the new unit and spliced its cable to the old cable in the mast. I also had to replace (on diffe...

920 Racing had an adjustable outhaul. 920 Cruising only had adjustment when the sail is completely slack.

My 920 does not have adjustable outhaul.

My panel is also dead. It produces about 9 volts only. A few years ago I replaced the original charge controller that went bad with a 30 amp controller. The panel wire and battery wire were accessible in a sliding door cabinet under the port window. A few years ago the connection wiring at the panel...

So here are the comments: as you can see, there is 1 wire stay connected on each side of the tip of the sprit to the eye on each ama. The geometry is such that it allows the sprit to be raised and lowered. there is a stay that connects to an eye low on the bow, then via blocks and rope to the tip of...

You should not need a winch at all to raise a main. You should only use the winch to tighten the halyard. I strongly advise you to find the source of the problem before a serious mishap happens. You should not wait until autumn. It's very easy to lower the mast on 800. Do not remove the jib. Just co...

gminkovsky

A few things to check: 1. Block at the top of the mast. Inspect and lubricate. It may be broken or jammed. 2. Block at the bottom of the mast and any deck organizers. You will only notice these problems under load. 3. You may have a broken sheave that jams the halyard under load. 4. Inspect your hal...

BTW, where are you getting the new waterstay? The last time i needed to replace waterstays it took me 2 years to get them!

gminkovsky

Yes, you should be able to do it in the water. I adjusted waterstays in the water multiple times. Just bring the boat into very shallow water, partly fold one side, go into the water and do it. You will need to open and fold a few times to adjust to proper tension.

gminkovsky

I do it the opposite: lie down on my stomach or side and reach with one hand and work blindly. Or better, let a young person (son, daughter) do it! What I found helpful is to insert the pin front to back so that cutter pin is more accessible. However, this resulted in the pin falling into the space ...

There is another way to connect to Seatalk: behind the electrical panel. That's how I connected a wireless remote for my autopilot. You just need a standard seatalk cable and possibly a seatalk Y splitter. I don't remember if I had an unused seatalk end behind a panel or added my own Y-splitter. I t...

There are a few posts on this forum regarding mooring (and anchoring), including my own detailed description. You should search and read all. The short answers: you should never have the boat folded except in protected waters or in a slip or at the dock. Even at the dock, the boat will be vulnerable...

Given a choice between an outboard and inboard diesel I would strongly prefer diesel for the following reasons: You can motor in waves. You get hot water. It is quieter. It is much more fuel efficient (not important in cost but in the amount of fuel to carry on a cruise). I don't know the difference...

gminkovsky

I believe that it is no longer recommended to use your adjustable backstay as a preventer. Especially bad if you forget to reconnect before you turn upwind or gybe. In 2003 when I got my boat, the recommended preventer was a separate line with blocks and cleat. The use is similar to boom vang as wel...

gminkovsky

I am not sure it is salt related. The lines get washed by very heavy rains. I think this is happening to all ropes as they age. I think UV does a lot of damage. Maybe UV + salt? I have some nylon ropes that I use in my backyard, and they are all very stiff. They haven't seen salt water in many years...

gminkovsky

As the boat is aging, many of the lines are becoming very stiff. This is especially a problem with ropes in cleats, such as board downhaul. The stiff lines just slide out of jam cleats. I put additional cover over the downhaul line but after a few years even the extra cover became too stiff and star...

I use 72mm lewmar synchro blocks with SWL ~2400 lbs (1100 kg) for all high load lines (preventer, reef, etc). My original Fredrickson blocks were replaced (under warranty) by 72mm ronstan with similar load. The only high-load block that I have is for the main halyard. I really like Lewmar. They are ...

according to the manual, each line is 7m long 8mm diameter. the manual states that it is polyester double-braid but i know for a fact that it is Dyneema (my downhaul line failed). I don't have first-hand experience replacing these lines but according to others, you need to remove table top and use a...

I run the main anchor rode to the cleat on main hull, and 2 bridle lines to the amas. I adjust the main line so it is somewhat slack. If I am only anchoring for a couple of hours I connect rode to the main hull and only one of the bridle lines to one ama. In this asymmetric setup the boat actually s...

Since you almost know Tim, you should talk to him. He will tell you why he switched back to 920 from 800. Keep in mind that both 800 and 920 draw more than 4 feet with board down. Of course, this does not prevent you from motoring or sailing downwind, and the board kicks up if you hit ground. The ba...

This is terrible. BTW, in preparation for a tropical storm, I take all sails down and remove everything from topsides. (I also add 3 additional mooring lines on top of the standard 3 that I normally use.) Rolled jib has a LOT of sail area. Main is not so bad if you are on a swing mooring. But broads...

how did it fail? which part broke? I had a few (5 or more) Fredricksen blocks fail. all in the same way: the plastic around the shackle pin disintegrated. I had some replaced under warranty. The rest I've been replacing with similar or higher spec aftermarket blocks. Personally, I prefer lewmar. The...

for the future, leave a thin messenger line in boom or mast when you remove the boom or take out a line. saves hours of labor when you put it back together.

now just use snake to thread a messenger line, then use messenger line to thread reefing line.

gminkovsky

fantastic! Feel free to come to long island and do any of this on my boat :-) looks like i am not putting my boat in the water this season... anyway, use electricians snake to thread the line through the boom sheaves. on 920 it is easier because the sheaves are exposed. still, takes 2 people with on...

gminkovsky

the rope becomes stiffer as it ages. you can change it or cut 10 cm at the block end so that a different part of it is in the cleat or put additional polyester cover over it. i had a similar problem with the board downhaul line on my 920. Also, a friend with a mono washes all his ropes in the washin...

That seems correct. My line is 8mm. BTW, the specs say it's only a polyester line, but i know for a fact that it is Dyneema core/Polyester cover ( found out when it failed!)

Re respirator: the one you use for dusty work is not necessarily correct for paint and solvents. Make sure to get the filter cartridge for VOC.

*** USE a RESPIRATOR ***.

Home Depot or Defender.. Just read the instructions to get the right kind.

My 920 requires just short of a gallon per coat. 1.5 gallon (6 l) is enough for 2 coats. You will probably need a little over 1 gallon for 2 coats. 2 gl will be enough for 3 coats, and then you can definitely skip painting next year!

gminkovsky

Just use a proper sealant to prevent moisture penetration. Do not put anything into the mount holes. Use screws 1 size larger. If the holes are already too large, fill with epoxy, then drill new holes for the larger size screws. The mount should have NO flexibility.

DF28 is a very fast but very tender boat. I don't think it can be easily depowered as demonstrated by the capsizes. (Read about multiple capsizes...) This is not a very forgiving boat, imo. For a novice, you will be fine on it in protected waters in good weather. But a mistake in gusty conditions on...

You are looking at a boat that is offering "camping style" accommodations and creature comforts! That and AC do not fit in the same sentence. You have to carefully consider what you want in a boat. Every boat is ALWAYS a compromise. I've sailed USVI and BVI during summer (on a mono). AC wa...

gminkovsky

On a 920 the screws are in solid glass with nothing else. the sealant is all around the mast step and between the mast step and the base. When my mast step was replaced, Quorning supplied massive screws. I would increase the size of the screws if you are replacing original.

gminkovsky

Bilge pump maybe?

My 920 has 2 hoses: 1 for electric, and 1 for a manual pump. They are about 5cm (2 inches) in diameter.

The smaller diameter hoses are fresh water. Mine are reinforced type.
