    who what where

    Why, that's the top of one of those new fangled carbon fiber masts! Stronger than steel huh?

    We were able to achieve some speed by picking our bow up when it was blowing. Surfing down waves at 12 kts in last years Monhegan Island race and kept the rudder in the water to fight off the round up. Point being that's why I'm bringing my questions here. Just because something worked for us one time doesn't mean it's right, hence trying to benefit from a larger and more informed perspective.

    Yeah, crew weight distribution can definitely be improved, still stacking folks like I was on the J/30. Luff tension was so loose because we started sailing 4-5 kt's of breeze. When is sprang up to 12-14, we neglected to correct for it.

    Those photos are from the MS regatta this year. We were setup for super light conditions and then the wind came up pretty abruptly on our way in. We were carrying that light air spin right to to very edge of a beam reach which is why it might look funny. That main itself is in great shape material wise, seems there is an opinion that it's shape is off? I'll post a couple more from that race and we have a bunch of photos on our facebook page. https://www.facebook.com/smalldogracing Our backup UK laminate is coming apart pretty drastically so we use that as the delivery sail. It's time for a new main, we have a great locker of foresails in good condition. Really like the idea of marking the runners for different conditions. Trouble is finding the "right" forestay sag. A lot of the successful boats around here swear by the "loose as hell" method even when the wind is up so it all depends on who you talk to.

    Bowman is wearing a pink foam squid hat. Yep.

    Anyone know how to sail a Mumm 36? Because we just bought one! It seemed like the right think to do after reading the forums and being specifically warned that they're difficult to sail to their rating and chew up inexperienced amateur racers. That's us! We were loosing our maintenance war with an aging J/30 and thought, how hard could it be?! We're having a blast, sailing her everywhere and trying to grab every race possible as the season winds down. The fun aside, and perhaps not surprisingly, we're not doing very well. We have the polars and just seem to be .3-.5 of a kt. slow no matter what we try. There are a few caveats. The mast jack did not come with the boat and we don't have a rod loose gauge yet (or a guide to what the numbers should be if we did) so rig tuning has been a lot of tacking back and forth and making slight adjustments to keep the rig straight (we can't seem to agree on the straight part either...). When we race, we spend a lot of time saying, "well this isn't working, lets try x", and, "well x certainly didn't work, time to move on to Y". We're generally finishing races alongside the J105's so we're definitely doing something, likely a great many things, wrong. I was hoping someone out there who might have spent time on this slightly geriatric racing machine would be able to impart a few tips in terms of trim and general racing. We've been generally sticking the main doctrine of higher traveler, more camber, more twist on light/choppy days and flatter leach, lower traveler, when the wind starts to build. We keep the no.1 close and leach closed in the light stuff and closer and more open as wind comes up. We pull on backstay, outhaul when the wind is climbing and keeping them soft when it's not. Definitely pull harder on the running stays when there is wind but probably not as hard as we should be (I'm terrified of the 6,500 lbs mark as we don't have a load cell). Not exactly sure how/when to be using the vang, been playing it like I would on the 30. Should we transition to dip pole when spin jibing? There is definitely great info on the form (we have our tacking choreography down!) but cant seem to find just a general tuning/trim guide for this boat. We understand that it will take time to learn this boat and sail her efficiently, if we ever figure it out at all. I'm aware that this post will probably attract all kinds of hate for us newer folks in over our head with too much boat and trying to stage a racing campaign. That's cool, I hope that I might be as cool/experienced as you someday. If anyone else would be so kind as to throw out a pointer or two, we'd be grateful. -Josh

    Drying out foam core

    I have done several areas of re-coring where there was delamination and the core has turned "rotty" or sludgy. During this process I found plenty of core that was still registering moisture content with my moisture meter but were dry to the touch, still had plenty of structure and where the layup and bonds were still bulletproof. Whats to be done for these areas? has some moisture but still structurally fine? I'd like to get moisture out of these areas so that they don't degrade in the future.

    Drying out foam core

    Could this method work for balsa core as well? Many area on my boat are still solid (no delam) but definitely carrying around a bit o' the ocean in my old J30. I'm cutting out and replacing some through hulls this year so I would have exposed core to run the vacuum line too and would drill holes in a grid pattern in the worst spots along the inside of the hull. I've got until April to let her sit with a de-humidifier, space heater and vacuum pump running... is it worth it? What kind of vacuum pump would be required? Is there a "correct" size to be effective? Would the setup be as simple as running a hose from the pump with an in line water separator?
