I tend to go no sumps and no holes on the sides or bottom of the tanks and a slight grade on the tank top. Where possible I fold the tank sides out of the bottom plate to reduce the welds. I try to keep water out of the tank, by using a water block fill filter and when possible I only fill...

I am currently using integral tanks in my home-built. It is lighter, adds structure, and doubles the bottom in areas. The tank top is also the cabin sole in places.

so far so good, just got in from a 800 mile trip and plan to go back out right behine this typhoon

I live in Pago Bay. Guam is a hard place to keep a boat. The typhoons are strong and common. I would enjoy showing you around but am on my boat till after Christmas. There is a group of traditional boat builders near the Baseball stadium, they meet on Saturdays and are friendly folks, the...

I was working on a project that had a single screw and two rudders - I found it interesting that the rudders turned at different rates. The designer (Vripack’s Dick Boon) swore it was the best thing for this boat.

I thought the “rule of thumb” was to leave a gap of about ½ the shaft diameter for water flow

Thank you'll for the valued information. I think I will get that 176 lb Claw and a barrel of chain for the primary and also keep the 135 lb cqr (on the bow roller) with 10 m of chain and the 1 1/8” nylon rode. The fortress lives in a locker with a short chain and a poly rode. The trip/...

I have a new "old boat". It’s going to weigh 35 tons loaded. I inherited a 135 pound CQR and a nice piece of 1 1/8” 12-strand, along with a big fortress. I want to add a primary anchor and am looking at 176 lbs Lewmar Horizon Claw for $750. 154 lb Rocna 70 for $2212.48 The price different is...

I don’t have drawings with me, but recall starting with a 10 knots boat at 100 horsepower; to get this we needed a slippery/light hull that would reach its theoretic hull speed at as low a horsepower per ton number as possible, something a little better them 3hp/ton. 8.4 knots or about 200...

Koliver : This engine came in from a hydraulic suppler with 12 hours on it about 10 years ago. I would have thought it new if it had been manufactured around that time. Glad to hear your TAMD41s are still new.

I always enjoy the insights on this forurm, My Volvo was originally considered for its inline six configurations and its relatively low rpm full power rating. This was important since the hydraulic pump being driven had a low maximum allowed rpm input rating. Now if I can get 14 knots out...

I have a 6 cylinder Volvo (tamd41 b896094) for a new project. Its an older engine with very few hours.

I agree with doing some testing, both roll period and incline. A short talk with a good naval architect may help. Maybe you can trade that zinc for lead. playing with boats is fun

I have an EPIRB, and a full ditch bag. I got a basic bag content list from a category one sailboat races list. I also keep wallets, cash and, anything the crew cares to put in. I have a hand held VHF, GPS, cell phone, and a windup radio with charger output. Do you’ll carry rafts?

When solo, I do the same with a slight addition I attach the snubber at the bow and run it aft. So I don’t have to walk forward with the ball hooked.

Worked on a few boats with Flap Foil Rudders, both single and double rudder installations. They were pretty impressive

Luckily its easy, I like to see if there is any sludge and check to see if the magnet caught anything.

My current engine had one motor oil dip stick installed and one blanked off taped port on the other side. I had to modify my oil pan and eliminated the drain plug. Using the blanked off port I installed a fixed oil pick up. To change the oil I use a West Marine Porta Quick Oil Changer. I drop...

I think you are right “fuel is the cheapest part of boating” Jewelry is my biggest expense.

It’s about one dollar a liter in the Philippines

I am heading to Palawan at the end of the month. Are any of you folks down there?

I have used teak HPL inside lockers and in high wear areas. After a good bronze wooling and a few coats of clear PU you could not tell.

Japanese whalers I get that comparison all the time, I guess they copied me. I will stay clear of all Japanese whalers. thanks
