Q1. How to assemble the suction cup to the curtain/mosquito net. 

A1. The mosquito net/curtain comes without the suctions cup mounted. It's because a suction cup can squeezed in the transport. A squeezed suction cup isn't broken but it looks broken. There is a simple instruction with pictures and all parts in the retail package. Done in a minute. (how to fix a squeezed suction cup).

Q2. How to mount a curtain on deep hatches and portlights.

A2. On some boats the deck and hull is very thick and it could be a problem to mount the curtain. There is supposed to be some tension when you mount the curtain but on a deep hatch it will bend the curtain in the edges. To solve this we have included a cord that you can prolong the suction cup with. This is included in all curtains (two for #1520 and #1515).

Q3. How to mount a suction cup on hatch made of fiberglass.

    A3. A hatch made out of fiberglass (instead of acrylic glass) has surface that isn’t 100% plane and the suction cup will have problem to stay put for a long time. It will leak in some air. To Solve this problem we need to mount a small plastic plate with double sided tape. It’s the kind of plate used in cars when you mount a GPS to the dashboard. This plate is sold as an accessories #1542 Plate for fiberglass hatch.

    Q4. How to mount a suction cup to a hatch with ventilation.

      A4. Most of the curtain/nets have a suction cup in the middle and that’s no problem. For blackout curtains we must use a curtain/blind with two suction cups #1520 Blackout curtain for hatches – regular with ventilation. For the large hatches the curtain #1515 already has two suctions cups. For mosquito nets it’s easy to the cord with suction cup to a side of the ventilation.

      Q5. Does the suction cup really sit all night?

        A5. As long as the suction cup and surface is clean there is no problem. It can sit for month or years without any problem. If it falls down there is dirt (grease or fat) on the suction cup or the window. Just clean it with some soap (or similar). On tempered glass there can be a thin film of grease and than you need something stronger than soap.

          

        Q6. How to fold the curtain/net.

          A6. It’s real easy (when you get a hang of it). 1. Hold the curtain/net with both hands and twist ~180°. 2. Pull your hands together. You will now see that curtain/net starts to fold. 3. When are done there should look like three rings. You may have to adjust the ring a little to have three ring of the same size.

          Q7. Does it really get 100% dark with the curtain/blind?

            A7. You can test the curtain by holding it up to a light bulb. On a bright sunny day it can be some light in the boat, not due to the curtain/blind but to light transmission of the hull. Fiberglass will let in more light than people in general knows. This is of course, also depending on boat type, a steal boat is different.

             

            Q8. How to measure the hatch/portlight to get the right size of curtain/net.

              A8. The curtain/mosquito net is mounted from the inside and should be larger than the hatch. This means there should be an overlap for the curtain/mosquito net. This also means the curtain/mosquito net also fits smaller hatch. Just measure the inside of the opening of the hatch. Often it's referred as the "cut out" size by the hatch manufacturing companies. You are supposed to measure side to side not across.

              The name of a hatch is often referred to the outside measure of a hatch. For example a standard Lewmar 60 has a hatch has a cut out size of 518x518 mm. 

              A general rule is that a standard hatch is ~50x50 cm and it's built so a normal person can climb out of the hatch. Boat owners with large hatches often knows that the hatch is large.

                Q9. How to measure the spreaders to get the right size of spreader boots.

                  A9. There are a large number of companies manufacturing spreaders in the world and our spreader boots will fits all brands. With the help of Velcro and a flexible edge the fitting will be universal.

                  1. Measure the size of the spreader. Measure not the tip of the spreaders but in the middle.
                  2. Then look to the rig and determine whether it is continuous or linked. A linked rig has a larger spreader tips and usually need a larger size. Refer to the table and select the size. There are four sizes to choose from and all spreader boot is sold in pair (starboard and port). We prefer to have the Velcro pointing backwards.
                  Are you still unsure you can email us info@waterlinedesign.se and we will help you choosing the right size. You can also buy two sizes and return the spreader boot that doesn’t fit. We have 60-day refund policy, but if you tell us we'll extend the refund time so you will have time to test them out on the boat.

                  Q10. How to straighten a folded suction cup.

                    A10. If a suction cup is squeezed for a period it will loose its original shape. A squeezed suction cup isn't broken. If you dip the suction cup into water 70°C/160°F, it will take its original shape.

                      

                    Q11. The mosquito net is getting "loose" in strong wind.

                      A11. This can be a problem and it’s easy solved. We have designed the cord holding up the net knowingly with a small/thin cord. People tend to pull the net very hard and then the net can break. It’s not easy and you need to use a great strength of force to break the net. With a thin cord you don’t pull that hard. It’s easy to change the cord to a thicker but you should be aware to not pull the net more then necessarily. You can buy the cord from us #9009 Cord – Heavy wind or you can just take any cord in the boat (it’s often cheaper). Often when it is heavy wind there is no mosquitoes, so the problem is very small.

                       

                      Q12. Are the nets good for really small bugs?

                        A12. Yes the meshes in the nets are really small and are designed to prevent even the “No-See-Ums”. In Sweden we have a large number of small gnats.

                         

                        Q13. The Spiroll is so long can I cut it in two pieces?

                          A13. Spiroll remains in place by friction and the size (wrapping and length) is developed for the dimension of rope. If you cut it in two pieces, Spiroll will be short and may start "walking" on the rope. You can secure with tape but it´s not something we recommend.

                           

                          Q14. The mosquito net has a large grommet. Doesn’t the bugs get in there?

                            A14. No the “lock” on the cord is like a round ball and it fits very nice in the grommet and will close it.

                            No mosquito though the grommet 

                            Q15. Why isn’t stainless steel in ring holding out the curtain/net?

                              A15. Stainless steel isn’t flexible enough. You wouldn’t be able to fold it. It’s made of chromed steel and even if it’s a marine environment it works perfect. The grommet is made out of brass and will not rust.
